FocusBuddy: Encouraging Healthy Desk-Work Habits by Caring for a Virtual Pet on a Water Bottle
Mohamed Ouf, Rowan Hussein
TL;DR
Desk workers may sit too long and drink less water than intended, while reminders can be mistimed and dismissed. FocusBuddy places a virtual pet on a water bottle and maps drinking, movement, and refilling onto pet care, then evaluates it in coursework use. Self-reported hydration and movement increased, but interviews showed that poorly timed prompts can create guilt; the proof of concept remains limited by its small sample, retrospective self-reports, and lack of a control condition.
Problem
Desk workers face prolonged sitting and insufficient hydration, while software reminders compete with focused work and are easily dismissed.
Method
FocusBuddy is a bottle-mounted virtual-pet prototype evaluated by 20 undergraduates during two weeks of regular coursework with written interviews.
Results
Median water intake rose from 3 to 4 cups per day, movement episodes rose from 2 to 4 per day, and all three targeted habits shifted in the healthy direction.
Takeaways & Limitations
Wellness prompts should respect focused work because pet framing can make self-care feel reciprocal but can also manufacture guilt when prompts are poorly timed.
Takeaways & Limitations
The evidence comes from 20 undergraduates using retrospective self-estimates without a control condition, limiting transferability and causal attribution.
Abstract

People who study or work at a desk sit for long uninterrupted periods and drink less water than they intend to. Software reminders address both problems but are easy to dismiss and easy to resent. We present FocusBuddy, a proof-of-concept fabric case that wraps a standard water bottle and houses a microcontroller, environmental sensors, and a small display showing a virtual pet. The pet's condition mirrors the user's self-care: drinking water feeds the pet, standing up to move plays with it, and refilling an empty bottle cleans it. Twenty undergraduate students used FocusBuddy for two weeks during their regular coursework and completed a written interview. Self-reported water intake rose from a median of 3 to 4 cups per day, movement episodes rose from 2 to 4 per day, and interviews surfaced two tensions: that wellness prompts must respect focused work, and that pet neglect can convert a wellness prompt into a source of guilt. We contribute the prototype, first-deployment evidence of healthy-direction shifts in self-reported habits, and design implications for emotionally framed wellness devices.
1 Introduction
FocusBuddy combines a virtual pet with a water-bottle case so caring for the pet maps onto drinking, moving, and maintaining a comfortable workspace. The proof-of-concept evaluation examined whether this framing could support healthier desk-work habits and when it might backfire.
- Motivation and problem: Prolonged sitting carries metabolic risk, while desk-work reminders are often mistimed, dismissed, and subject to notification fatigue.The challenge is timing and motivation rather than awareness alone.
- Design concept: FocusBuddy embeds a virtual pet in a standard water-bottle case, linking pet needs to the user’s drinking, movement, and room comfort.The prototype uses a hobby microcontroller, fabric, buttons, and an LED matrix, avoiding custom hardware.
- Evaluation: The study evaluated FocusBuddy with 20 undergraduates during regular coursework and collected structured written interviews.The evaluation targeted self-reported habit shifts and users’ experiences of emotionally framed prompts.
- Contributions: The paper contributes a prototype, initial evidence of self-reported shifts in hydration, movement, and uninterrupted sitting, and qualitative findings about when pet framing helps or backfires.These findings motivate design implications for emotionally framed wellness devices.
2 Related Work
Related work connects health behavior change with game-like caretaking metaphors and tangible peripheral objects. FocusBuddy combines these strands by making a water bottle the permanent home of a pet whose needs include hydration, movement, and room conditions.
- Desk-work interventions: Sedentary-behavior research emphasizes breaking up long sitting bouts, while break-prompting systems must negotiate interruptions around users’ tasks.Poorly timed prompts impose cost and stress, whereas deferral to task boundaries can reduce that cost.
- Gamified health: Gamified health interventions use metaphors such as gardens, fish, and virtual pets, but their effects are mixed and context-dependent.Prior systems have linked physical activity or healthy eating to the wellbeing of virtual entities.
- Tangible feedback: Tangible wellness systems move feedback into peripheral everyday objects, including desk sculptures, mugs, bottles, and bracelets.These systems follow the idea that calm technology should remain at the periphery of attention.
- FocusBuddy’s position: FocusBuddy makes the bottle the permanent home of a dependent pet whose needs extend beyond drinking to movement and the surrounding room.Unlike Playful Bottle’s phone-docked creature, the object users care for is also the object used for self-care.
3 The FocusBuddy Prototype
FocusBuddy evolved from a rejected desk companion into a bottle-mounted prototype developed through Wizard-of-Oz testing. Its pet translates drinking, movement, refilling, and environmental adjustment into care actions with rewards and penalties.
- Design evolution: Testers rejected an added bear-shaped desk object, redirecting the companion concept onto a water bottle already carried by users.A paper-and-cardboard case was then explored in Wizard-of-Oz sessions before building the working prototype.
- Hardware: The working prototype is a fabric sleeve with a micro:bit display and sensors, Skip and Refill buttons, and a 3D-printed battery base.The micro:bit supplies a 5×5 LED matrix, accelerometer, temperature sensor, light sensor, and microphone.
- Pet needs: Drinking feeds the pet, refilling an empty bottle cleans it, and carrying the bottle during a walk or stretch relieves boredom.Drinking is detected through bottle-tipping motion, while refill requires pressing Refill.
- Environmental interaction: Environmental conditions such as darkness, noise, or cold make the pet uncomfortable and prompt users to adjust the room.Figure 5 depicts walking with the pet and adjusting lighting after an environment prompt.
- Feedback and control: Completed care actions add points and trigger happy animations, ignored prompts subtract points, and Skip dismisses a prompt at a small point cost.At zero points the pet dies, while Skip provides an escape hatch for busy moments.
4 Study
The study used a two-week coursework deployment and written interviews to compare participants’ pre-study and final-week habit estimates. It combined paired nonparametric tests with inductive coding of open-ended responses.
- Research questions: The evaluation asked whether FocusBuddy coincided with changes in hydration, movement, and sitting, and how users experienced wellness prompts delivered as pet needs.Written interviews captured both pre/post self-estimates and open-ended accounts at low burden.
- Participants: 20 undergraduates aged 18 to 23 participated, with 10 recruited from Queen’s University and 10 from the University of Ottawa.All reported substantial weekday desk time, ranging from 4–6 hours to over 10 hours.
- Procedure: Participants used a FocusBuddy unit during normal coursework for two weeks, with usage varying from 0–2 to 10 or more days.Afterward, they completed a three-part written interview including typical-workday estimates before the study and during its last week.
- Analysis: Paired habit estimates were analyzed with two-sided exact Wilcoxon signed-rank tests using Bonferroni-corrected α = .0167 and matched-pairs rank-biserial correlations.Open-ended responses were coded inductively, with themes reported when at least three participants expressed them.
- Study measures: Figure 6 compares individual participants’ self-reported habits before the study and during its last week, with gray lines for individuals and blue labels for medians.The figure includes n = 20 participants.
5 Findings
FocusBuddy coincided with healthy-direction shifts in self-reported hydration, movement, and sitting, while interviews revealed that timing, legibility, portability, and pet framing shaped whether prompts helped or backfired.
- 5.1 Self-Reported Behavior Change: Median water intake while working rose from 3 to 4 cups per day, movement episodes from 2 to 4, and the longest sitting period fell from 162.5 to 90 minutes.Mean water intake rose 45%, mean movement episodes 86%, and mean longest sitting period fell 32%; the authors interpret these as directional rather than calibrated magnitudes.
- 5.1 Self-Reported Behavior Change: The two participants who used FocusBuddy on 2 or fewer days reported no improvement on any measure, while one heavy-deadline participant reported drinking less and sitting longer.The authors state that the shifts track engagement rather than mere possession of the device.
- 5.1 Self-Reported Behavior Change: Ease of use was the strongest agreement rating, while requirements fit and intention to keep using FocusBuddy were moderate; pet pressure was low on average but maximal for one participant.The spread in ratings was explained by participants’ written responses.
- 5.2 Timing Decides Whether Prompts Help: Eight of 20 participants reported prompts landing mid-focus, and requested snoozing, rescheduling, quiet hours, deadline modes, or grace periods instead of costly immediate responses.Participants generally accepted the prompt goal but objected to interruption costs; one participant acted on a prompt that arrived just after solving a difficult problem.
- 5.3 The Pet Cuts Both Ways: The pet reframed self-care as reciprocal for some participants, but guilt, reprimand-like reactions, and disinterest led others to prefer neutral or decoupled feedback.Three participants independently proposed separating wellness prompts from the pet’s mood or selecting a neutral feedback style.
- 5.5 Legibility of a Tiny Pet: Four participants struggled to read the 5×5 pet when prompts mattered, because ambiguous icons and lengthy animations competed with plainly stating the requested action.Reward visuals could hide the next reminder time, and small labels were difficult to read in dim rooms.
- 5.6 Fitting Shared Spaces and Bags: Three participants encountered portability limits in shared spaces, including social attention, awkward sound cues, and a bulky case that was left behind.The authors conclude that a device attached to an everyday object inherits the social settings entered by that object.
6 Discussion
FocusBuddy’s deployment suggests that emotionally framed self-care can shift desk-work habits, but its benefits depend on respecting focused work and avoiding guilt. The study’s limited sample and retrospective, uncontrolled measures justify a better-instrumented next iteration rather than strong causal claims.
- 6.2 Emotional Stakes Need an Asymmetry: Attachment made caring for the pet and caring for oneself emotionally meaningful, but declining pet states could feel accusatory under deadline pressure.The authors propose forgiving lapses quickly while celebrating care conspicuously.
- 6.2 Emotional Stakes Need an Asymmetry: Making the emotional layer optional acknowledges that attachment is a preference rather than a universal motivator.The discussion cautions against treating users as one uniform population.
- 6.3 Respecting Focus: Participants requested snooze without penalty, quiet hours, and post-break grace periods so wellness prompts would respect focused work.Existing accelerometer, microphone, and light sensors could support inexpensive focus and meeting detection.
- 6.4 Limitations: The 20-undergraduate sample, retrospective self-estimates, absent control condition, and short deployment limit transferability and causal attribution.The before-study estimates were collected in the same end-of-study interview, inviting recall and demand biases.
- 6.5 Next Iteration: A thinner hardware iteration with a higher-resolution display, inertial unit, and environmental sensors could improve pet expressiveness and sensing confirmation.The proposed package would support explicit acknowledgment of care actions and on-device activity inference.
7 Conclusion
FocusBuddy links self-care to caring for a virtual pet embedded in a water-bottle case. Its initial deployment suggests healthy-direction habit shifts, while showing that the pet’s emotional framing can both support reciprocal self-care and manufacture guilt.
- 7 Conclusion: FocusBuddy makes caring for a virtual pet and caring for oneself the same actions through a water-bottle case.The pet’s feelings provide both the design’s motivational power and its risk.
- 7 Conclusion: The proof of concept supports a serious second iteration that forgives lapses as readily as it asks to be fed.This conclusion follows from the design’s reported behavioral promise and guilt risk.
