Blog Post 4: Exploring IoT in Retail

IoT for Retail Applications

2.1 Real-Time Inventory Management

One of the most impactful uses of IoT in retail is real-time inventory tracking. Traditionally, stores rely on manual checks or clunky barcode systems that are time-consuming and prone to error. With IoT:

• RFID Tags: Clothing retailer Zara has widely adopted RFID tags to automate inventory counts, reducing out-of-stock situations and improving shelf availability. Store employees can wave an RFID reader over a rack and instantly know which sizes and colors need replenishing.

• Beacons: Placed strategically in aisles, these small devices automatically detect and log inventory data. They also help store staff locate products or direct customers to specific items. In some supermarkets, beacons linked to a mobile app can alert staff to low inventory in high-demand sections (e.g., bottled water during a heatwave).

Case Study: Walmart

Walmart has been testing “smart shelves” in multiple locations. These shelves use weight sensors and RFID tags to monitor product levels. When an item runs low, the system automatically alerts staff (or even dispatches autonomous robots) to restock. The result is fewer stockouts and a smoother shopping experience.

2.2 Personalized Marketing & Customer Engagement

IoT enables hyper-personalized shopper experiences. By integrating beacons, apps, and loyalty programs, retailers can tailor offers to each customer’s location and preferences.

• Beacon-Triggered Notifications: Large department stores like Macy’s in the U.S. have experimented with beacon technology to send special deals or product suggestions to a shopper’s phone as they pass specific sections, like cosmetics or footwear.

• Loyalty Programs: Grocery chains in Asia, such as Aeon in Japan, have started integrating location-based offers with loyalty apps. When a customer walks into a store, the app can highlight discounts on items they frequently purchase. This not only increases sales but also makes the customer feel valued and understood.

Case Study: Starbucks

While not strictly an in-store beacon case, Starbucks has embraced IoT in a broader sense. Its mobile app tracks buying patterns and uses location data to offer personalized drink recommendations, birthday perks, and seasonal promotions in real time. This data-driven approach is integral to Starbucks’ loyalty strategy, encouraging customers to keep coming back for more.

Level Up Your Gains: The Benefits of Mascot Based Gameplay

Games featuring mascot gameplay—where players nurture and care for virtual pets or similar characters—offer a distinct experience that sets them apart from games without such mechanics. These games tap into players’ emotional cores, creating bonds that extend beyond simple gameplay. This connection fosters unique engagement, often blending entertainment with emotional and psychological benefits. By exploring the dynamics of these games, we can better understand why they resonate so deeply with players.

Emotional Attachment and Responsibility
Caring for a virtual pet encourages players to build an emotional attachment through repetitive, nurturing interactions. These games simulate the experience of having a dependent creature, which naturally elicits feelings of responsibility. For instance, players may feed, groom, or play with their virtual companions, and neglecting these tasks can result in consequences like an unhappy or sick pet. This interplay of care and accountability fosters a sense of purpose and consistency in player behavior. Unlike traditional games, where engagement is tied to objectives like defeating enemies or solving puzzles, mascot gameplay intertwines success with the pet’s well-being. Research suggests this attachment can positively impact empathy and nurturing behaviors in real life, potentially making players more attuned to caring for others.

Enhanced Engagement through Personalization
Mascot gameplay frequently allows players to deeply personalize their virtual pets, which strengthens the emotional bond between the player and the game. Players often have the opportunity to name their pets, customize their appearances, and influence their behaviors or attributes through choices made in the game. This level of personalization fosters a sense of ownership and pride, transforming what could otherwise be a generic in-game character into something truly unique. This customization keeps players invested, as they are not simply progressing in the game but are actively building a relationship with a personalized entity. As a result, the more effort players put into shaping their pets, the more likely they are to stay engaged over time. By comparison, games without this level of customization may struggle to build similar levels of attachment or long-term engagement.

Stress Reduction and Mental Well-being
Interacting with virtual pets is not just entertaining—it can also have therapeutic benefits. Many players report feelings of relaxation and reduced stress while caring for their virtual companions, as the low-stakes yet rewarding nature of these interactions creates a calming experience. For individuals who cannot own real pets due to financial, health, or logistical constraints, virtual alternatives can offer similar companionship and emotional fulfillment. These games simulate the psychological benefits of real pet ownership, such as alleviating loneliness and providing a structured sense of responsibility. Studies and community discussions highlight how this connection improves players’ mental health, serving as a digital form of pet therapy. By offering a blend of escapism and companionship, virtual pet games position themselves as more than just entertainment—they become a source of emotional support.

Community Building and Social Interaction
The social dimensions of virtual pet games further distinguish them in the gaming landscape. Many of these games incorporate multiplayer or community-driven elements, such as trading pets, participating in competitions, or joining forums to share tips and stories. These social mechanics create opportunities for players to connect, fostering a sense of community around shared interests. Unlike games focused solely on individual progression, mascot-based games often emphasize collaboration and collective achievements. This interconnectedness enhances the experience, as players not only bond with their pets but also with like-minded individuals. These communities are not just secondary features; they often become the heart of the game, reinforcing player loyalty and encouraging long-term engagement.

Differentiation from Non-Pet Games
Games without virtual pet mechanics often focus on external goals, such as achieving high scores, completing missions, or mastering complex challenges. While these elements offer excitement and intellectual stimulation, they may lack the depth of personal connection that mascot gameplay provides. The act of nurturing a virtual pet introduces a softer, more empathetic dimension to gaming. It shifts the focus from external achievement to the internal satisfaction of caring for another being. This emotional engagement can make mascot games feel more rewarding over time, as the gratification stems from the player’s relationship with their pet rather than the completion of isolated tasks. In this way, mascot games stand out by blending emotional fulfillment with gameplay mechanics, offering a unique hybrid experience.

Conclusion

Mascot-based games with virtual pets differentiate themselves by fostering emotional bonds, enabling personalization, and offering psychological benefits that traditional games often lack. The cited research and community insights emphasize the importance of emotional engagement and responsibility in these games, which lead to increased empathy, reduced stress, and a greater sense of purpose. The integration of social features further enriches the gaming experience, creating communities that amplify the emotional connection between players and their pets. In contrast, games without virtual caregiving mechanics focus on external goals, which can limit their ability to resonate on a personal level. Ultimately, mascot gameplay is not just about entertainment—it’s about creating meaningful, enduring experiences that connect players to their virtual companions and to one another.

#02 Human Senses

How do different combinations of visual, auditory, and tactile cues influence users’ ability to detect and interpret complex pattern in data?

Human Senses and Beyond

When we talk about the human senses, the classic list of sight, sound, smell, touch, and taste usually comes to mind. However, there is growing evidence that humans perceive the world through far more than these five fundamental channels. In addition to balance, proprioception (awareness of body position), and temperature sensation, researchers continue to uncover other nuanced ways in which we sense and interpret our surroundings.
https://aeon.co/videos/aristotle-was-wrong-and-so-are-we-there-are-far-more-than-five-senses

For the scope of this research, I will concentrate on sight, sound, and touch—particularly regarding how data can be represented and experienced through these modalities.


Accessibility in Design

In modern design practice, accessibility is a fundamental principle rather than an afterthought. Whether creating websites, data visualizations, or interactive installations, designers should integrate accessibility guidelines from the start. These guidelines typically include:

  • Color Contrast and Shape Differentiation
    Ensuring legibility and clarity for individuals with various visual abilities, including color blindness.
  • Alternative Text and Descriptions
    Providing alt text for images and clear labeling for data charts to support screen readers.
  • Flexible Interaction Methods
    Offering keyboard or alternate navigation modes for users who cannot interact with a mouse or touch interfaces.

Adhering to these practices benefits not just users with disabilities; it often leads to improved usability and clarity for everyone.

Listen, Feel, Hear the Data

Sonification: Transforming Data into Sound

Definition and Rationale
Sonification involves mapping numerical data or other abstract information to audible properties such as pitch, volume, rhythm, or timbre. Its fundamental goal is to leverage the human auditory system’s sensitivity to changes in frequency and amplitude. This can be particularly useful when data contains temporal patterns or fluctuations that might be more readily perceived through sound than sight.

  • Time-Based Patterns: For datasets that evolve rapidly, detecting a small uptick or sudden dip is sometimes easier when it’s rendered as a change in pitch or tempo.
  • Parallel Processing: The brain processes auditory and visual stimuli along different pathways, so combining both channels can help distribute cognitive load.
  • Inclusive Experiences: Individuals with visual impairments or color-vision deficiencies can gain richer insights by “listening” to data, reducing reliance on purely visual cues.
Design Considerations
  1. Data-to-Sound Mapping: Deciding which data variables map to pitch, volume, or rhythmic patterns is crucial. Overly complex mappings can overwhelm users, while oversimplified mappings might convey only superficial insights.
  2. Contextual Meaning: Providing brief textual or spoken labels can clarify what changes in pitch or tempo signify, helping users build intuitive mental models.
  3. Avoiding Auditory Overload: Continuous, intense auditory cues can be fatiguing. Subtle sound cues or situational “alerts” (playing a specific note only when a threshold is crossed) often strike a better balance.

Tactile Interfaces: Feeling the Data

Definition and Applications
Tactile interfaces, often called haptic interfaces, communicate information through the sense of touch—vibrations, pressure, temperature changes, or textural shifts. This approach is notably valuable for individuals with visual or auditory impairments, but it also holds potential for creating richer, more immersive data experiences for all users.

  • Vibrotactile Feedback: Short pulses or vibration patterns can indicate specific data thresholds or events, such as crossing a predefined limit or detecting an anomaly.
  • Physical or 3D Representations: Tactile data displays can take the form of raised surfaces, 3D-printed graphs, or shape-changing interfaces. Users can literally feel the peaks, troughs, or relationships in data.
  • Thermal or Pressure Feedback: Emerging technologies allow for subtle temperature changes or pneumatic feedback. For instance, temperature gradients might mirror climate data, enabling users to “feel” environmental shifts over time.
Design Considerations

Integration with Other Senses: Tactile interfaces often work best with visual or auditory cues. Each modality can reinforce or clarify the other, fostering a more complete understanding of the data.

Tactile Resolution: Human touch has limits in distinguishing small differences in vibration frequency or texture. Designers must tailor the granularity of feedback to what users can reliably perceive.

Attention and Comfort: Continuous or intense haptic signals can lead to sensory fatigue. Designers should consider using event-based or gentle transitions to avoid discomfort.


Connecting Sensory Design and Accessibility

The overarching theme linking these ideas is that designing for accessibility often creates a more inclusive, engaging experience for everyone. This approach demands thoughtful consideration of how data is conveyed: beyond color and labels, it involves weaving together sight, sound, and touch. Whether in assistive technologies, artistic installations, or everyday data dashboards, a multisensory perspective can expand what is possible in data communication.

Level Up Your Gains: Current Landscape of Gamified Strength Training Apps

The hype around fitness and the growth of a more health-conscious generation has not only led to a rise in fitness studio subscriptions but also fitness related apps supporting users in their fitness journey.
It is not surprising that some have went beyond simply tracking progress and started gamifying your workouts. However, while the market for gamified endurance sports apps is well developed, strength training remains an area with potential. This post investigates a range of current strength training and rep-tracking apps, analyzing their strengths, weaknesses, and gaps that a gamified mascot-based strength app could fill.

1. HeroFit

HeroFit gamifies strength training by letting users level up avatars and earn rewards through workout completion. Its leaderboard and progression features encourage friendly competition and consistent use.

Where it falls short:
The app only scratches the surface of gamification and lacks more engaging content/functions which could lead to getting disinterested quickly. It’s focus on external competition may also discourage users who are not driven by rankings or social comparison. Additionally, it lacks personalized, adaptive challenges based on the user’s progress.

2. Workout Quest

Workout Quest integrates RPG-style quests, where users earn experience points and “level up” by completing exercises. The adventure-based narrative adds a fun twist to strength training.

Where it falls short:
Its gamification is mostly surface-level, with limited integration into actual workout tracking. The app could offer more robust analytics and deeper customization for different fitness levels.

3. Nerd Fitness Journey

Nerd Fitness Journey uses gamification to help users progress through fitness “missions” in a game-like format. It combines nerd culture with fitness, providing users with creative challenges tied to fandoms like Star Wars or superheroes.

Where it falls short:
While its themes are engaging, the app lacks strong rep-tracking features and strength-specific guidance. Additionally, the gamified missions often feel loosely connected to actual strength progression, making it less effective for serious lifters.

4. Treeceps

Treeceps offers a mix of workout tracking and gamified elements, encouraging users to complete strength-training workouts to progress within the game.

Where it falls short:
The app struggles to differentiate itself from competitors. Its narrative and progression systems feel underdeveloped, and it lacks unique elements that would make it stand out.

5. Zombies, Run! (Endurance Sport Example)

This app demonstrates how to create an immersive narrative experience, motivating users with a compelling storyline and rewards tied to activity.

Where it falls short (for strength training):
Zombies, Run! is heavily focused on cardio. While it succeeds in gamifying endurance training, it provides little insight for adapting similar concepts to strength workouts.

General Takeaways

Across the board, these apps face several challenges:

1. Shallow Gamification: Many apps fail to integrate gamification deeply into the workout process. Points, badges, and leaderboards are motivating but often lack a sense of long-term progression or narrative depth.

2. Lack of Personalization: Few apps offer truly adaptive systems that adjust based on user progress, fitness goals, or skill level.

3. Limited Emotional Engagement: Existing apps rarely create a personal connection with users, relying on extrinsic motivation rather than intrinsic factors like emotional investment.

The Opportunity: A Mascot Based Strength Tracking App

A Mascot-based app for strength training could fill a unique niche in this space by addressing the above gaps. Here’s how:

• Deep Emotional Engagement: Users could “raise” a virtual character (like a Tamagotchi) whose progress and well-being depend on their workouts. Skipping a session could lead to setbacks for the character, creating a sense of responsibility and emotional connection.

• Intrinsic Motivation: Instead of external competition, users would focus on caring for their character and watching it grow. This fosters a more personal and sustained sense of motivation.

• Adaptive Progression: The app could introduce challenges and “boss battles” tailored to the user’s fitness level. For example, attempting a personal record could unlock a new stage in the game.

• Story-Driven Narrative: Much like Zombies, Run!, the app could incorporate an engaging storyline that evolves as the user trains, adding depth and continuity to the gamified experience.

Conclusion

While the current offerings in gamified strength training have laid a solid foundation, they leave much to be desired in terms of depth, personalization, and emotional engagement. A Tamagotchi-inspired app could bridge these gaps, creating a new standard for gamified fitness that is both fun and meaningful. By combining interactive storytelling, adaptive challenges, and emotional investment, such an app has the potential to revolutionize how people approach strength training.

2.2 Augmented Reality (AR)

Definition

Augmented Reality (AR) integrates digital elements into a real-world environment, enhancing user perception via overlays on a physical space.

Types of AR

  1. Marker-Based AR

• Relies on predefined triggers (QR codes, images, or specific objects) to launch an AR experience.

• Commonly used for virtual try-ons, visualizing furniture in-home, or interactive product packaging.

  1. Markerless AR

• Utilizes GPS, sensor data, or computer vision to map surroundings in real-time, enabling more dynamic and spontaneous overlays.

• Often used for in-store navigation or advanced outdoor experiences; typically requires more complex hardware and higher computational power.

  1. Projection-Based AR

• Projects digital images directly onto physical surfaces. For retail, this could be used in interactive displays that overlay information onto products in-store.

Why AR Matters in Retail

• Immersive Customer Experiences: Virtual try-ons for clothing or makeup, making it easier for customers to visualize products.

• In-Store Navigation: AR can guide customers to specific products, highlight promotions, or provide additional product details.

• Customer Confidence: By seeing how products look or work in real-time, shoppers are more likely to make informed purchasing decisions.

Retail-Specific AR Use Cases

Virtual Try-Ons (Fashion, Cosmetics)

One of the most common AR applications in retail is the virtual try-on feature. By using a smartphone camera or a smart mirror in-store, customers can see how clothes or makeup products look on them before making a purchase. This reduces the need for physical trials and can help customers explore different styles more quickly.

Interactive Product Demos (Furniture, Electronics)

Imagine seeing how a new coffee table or TV would fit in your living room without having to measure or rearrange furniture. AR applications allow shoppers to “place” digital models of products into their homes. This not only boosts customer confidence in the purchase decision but also cuts down on returns and exchanges.

Software Tools

• Unity: A popular game engine that supports AR development through various plugins.

• Vuforia: One of the first AR development platforms; integrates well with Unity for marker-based AR experiences.

• ARKit (iOS) and ARCore (Android): Native AR development kits from Apple and Google, respectively. These frameworks offer markerless tracking, surface detection, and more advanced features to create realistic AR scenes.

Hardware Considerations

• Smartphones: Currently the most ubiquitous AR hardware. Almost everyone has a smartphone with a camera, making AR experiences accessible to a large audience.

03 Informal survey

Before the Christmas break I created a quick survey to determine whether the people in my bubble share similar frustrations with current digital healthcare solutions. It’s not a highly scientific study; rather, I’m gathering ideas and seeking confirmation that there’s room for improvement in the digital health sector.

I received 11 responses and learned that many people may not engage with questionnaires, even short ones. Maybe it was also due to the holidays and people were busy eating cookies. For my official survey, I’ll need to reach out to a larger audience or focus on obtaining quality data rather than just quantitative results. If you’re reading this and would like to contribute, you can participate in the questionnaire by following this link. It only takes 5 minutes 😉 https://forms.gle/rSiXXLivi6TypXwUA

Results

Below you will find screenshots of the results.

In conclusion, this informal questionnaire has served as a valuable test run, providing insights into what I need to consider for the official round as I move closer to completing my thesis.

#03 Are we living in an epidemic of loneliness?

The heightened risk of loneliness during the COVID-19 pandemic has brought increased attention to the issue, leading to loneliness and social isolation being recognized as serious public health concerns.1 A study conducted by the IFO Institute and the European Commission reveals that in 2016, 12 % of people in the European Union frequently experienced the feeling of loneliness. During the initial months of lockdown, this figure increased to 25%. 2

Some researchers even claim that we are living in an epidemic of loneliness right now. However, loneliness is not a modern-day phenomenon. A study by the American Psychological Association analyzed 345 studies comprising 437 independent samples, with a total of 124,855 young adults completing the UCLA Loneliness Scale between 1976 and 2019. Over these 43 years, the study revealed a gradual increase in loneliness. Even though there was constant increase in loneliness, talking about an epidemic of loneliness might be exaggerated. 3

Who is at highest risk for loneliness?

Age is a frequently studied aspect in connection with loneliness. For a long time, the focus was on older people, as they have a particularly high risk of being affected by loneliness. However more recent studied showed that there is a u-shaped relationship between age and loneliness, because also young people are highly affected by loneliness these days. 4

Examining socio-economic factors such as income, health, and living conditions, several studies indicate that individuals with lower income levels are more likely to experience loneliness. Similarly, those who report poor health tend to feel lonelier compared to individuals with good health. Furthermore, research shows that individuals living alone are more likely to experience loneliness. 2 5

Additionally, technology, particularly social media, has a significant impact on our relationships and social interactions. Even though we are more connected than ever, people tend to feel more lonely nowadays. Excessive social media use (in the study from the European commission excessive means two or more hours per day on social media) can contribute to feelings of loneliness, a fear of missing out, and a lack of meaningful social connection. 6 7

Since several studies show the negative impact of loneliness on health and its growing significance in public health, several governments and institutions — such as the government of United Kingdom and Japan, the Ministry of Health in the Netherlands, and the European Commission — are developing strategies to combat loneliness. 2 

The next blog post explains which impact loneliness has on our health.
