Busy tech professionals frequently struggle with delayed sleep onset and disrupted, non-restorative rest, due to heavy workloads, extended device usage, and lifestyle stressors that undermine both focus and health.

Introduction to the Problem

Although sleep-tracking apps, wearables, and smart home integrations exist, none offer a cohesive, data-driven solution. 

Current systems fail to integrate behavioural data, environmental cues, nutritional guidance, and expert advice, leaving professionals with disjointed solutions that don't address all factors affecting sleep.

Secondary Research

About 30 to 35% of the general population complains about sleep problems, and 9 to 11% suffer from chronic insomnia.

Sleep problems in population

Sleep Deprivation Effects

A study shows that sleep deprivation slows responses, increases focus lapses and errors, and heightens time-on-task effects, resulting in a lack of productivity.

Long Term Effects

In the long term, it impairs brain function and stresses the immune system, contributing to even mental disorders.

Assumptions

I began with a set of initial assumptions that informed the direction of my research and user interviews, helping me identify key areas for exploration.

I believe my users understand that:

  1. maintaining healthy sleep habits can significantly enhance their overall well-being and productivity.

I also believe my users need:

  1. single, integrated digital solution that consolidates their sleep management tools & provides cohesive and actionable insights.

  2. targeted interventions to manage digital distractions and stress levels to create a calming, sleep-conducive environment.

These assumptions served as a foundation for guiding my user research, interview process, and ideation of potential solutions.

Hypothesis

I formulated the following hypothesis to test during my research:

I believe that if tech-savvy professionals are provided with a single, integrated digital solution that consolidates their sleep management tools and delivers actionable insights, along with targeted interventions, then they will be more likely to adopt and sustain sleep-friendly behaviours.

I will consider this hypothesis supported if at least two out of three interviewees express frustration with their current sleep management methods and indicate that these methods are ineffective in improving their sleep quality, productivity, or overall well-being.

Research Methodology - USER INTERVIEWS

This method allows for a direct, in-depth exploration of participant’s personal experiences, motivations, and frustrations around sleep.

By engaging in open-ended conversations, we can uncover nuanced insights that surveys or purely quantitative methods might overlook.

  • Health Status:

    Include individuals facing trouble in falling asleep faster and achieving deeper, restorative sleep.

    Include individuals who believe their productivity is hampered my lack of sleep.

    Includes individuals who used to have sleep issues but have learned to manage their sleep.

    Tech Literacy:

    Recruit participants with varying comfort levels using digital tools (e.g., apps, wearables).

    Demographics:

    Seek professionals in age group of 30-45.

Hypothesis validation

After the interview, it turned out that 3 out of 3 interviewees expressed a desire for an integrated solution for sleep management tools and delivers actionable insights, along with targeted interventions to promote faster sleep onset and deeper, restorative sleep.

So, How might we…

enable busy professionals facing sleep challenges to adopt a solution that seamlessly integrates sleep tracking tools with actionable insights & targeted interventions to promote faster sleep onset and deeper, restorative sleep?

Affinity Mapping

Sleep Latency, dissruption & Quality

Click on images to expand.

To understand user interviews, I sorted and grouped participant responses to uncover consistent pain points, user behaviours, and key goals.

As I dug deeper, meaningful patterns began to surface, highlighting various themes.

Participants reported difficulties with falling asleep and achieving uninterrupted & deep sleep.

Impact on Productivity & Long-Term Health

Poor and inconsistent sleep is directly linked to reduced concentration and productivity, as well as potential long-term health risks.

Inconsistent Sleep Strategies

Natural methods like meditation, exercise and controlled screen time are disjointed. There’s a strong desire for an integrated solution.

After evaluating each theme, I chose to focus on

“Inconsistent Sleep Strategies”

My rationale was straightforward:

  1. Rather than creating entirely new solutions, the goal was to unify existing yet fragmented strategies into a cohesive approach.

  2. Interview findings further revealed that while participants understood sleep hygiene, they struggled to put together & maintain consistent routines, highlighting a clear opportunity for digital intervention.

User Persona

To better understand user needs, I created a persona, Ravi Kapoor, reflecting the target audience’s sleep struggles.

"If I can’t sleep quickly, I’m doomed to face another day with my brain running on fumes."

PROGRESS MODAL FOR SELECTED ROUTINE

Initial Low Fidelity Wireframes

To refine the user experience through usability testing, I converted the selected screens into low-fidelity wireframes using Figma. This step also helps to visualize & understand the task flow.

Usability Testing

This phase underscored how vital testing and iteration are towards successful design. Testing early played a key role in challenging assumptions, spotting usability issues, and collecting feedback that shaped improvements.

I decided to have 2 rounds of testing for my prototype. On the right, you can see the tasks for usability testing. I choose Zoom as my testing medium.

  • The initial step requires the user to identify the primary access point for connecting a new device within the SleepSense application. Users are expected to explore the dashboard and navigate to the “Routine” screen, which displays the available routine types. For this task, the user must select the 'Winding Down' routine.

  • Upon selecting the 'Winding Down' routine, the application will present a list of reminder
    options. In this step, the user is required to update their preferred method of receiving
    reminders.

  • After updating the reminder settings, the application will display the complete 'Winding Down' routine with all its associated steps. The user must review the steps and confirm acceptance of the routine.

  • Once the routine has been accepted, the final step is to receive the corresponding reminders. The
    application should offer visual feedback such as a progress bar or confirmation message to indicate that the routine is being executed. The prototype will be evaluated based on User’s awareness throughout the task and the ease with which they complete the routine.

Design Prioritization Matrix: Round 1

After the 1st round of usability tests, I received the following feedback and on the right prioritized results on the Design Prioritization Matrix based on impact & efforts.

1. Align sleep time like the rest of the form fields in the routine screen.

2. Provide a checkbox option to select steps of the routine that are applicable in the winding-down routine screen.

3. Include an “arrow” icon to show that the reminder tile in the dashboard will expand to a screen.

4. The progress bar needs a label & progress percentage for better awareness of the routine stage.

5. Include links to the articles listed on the reminder screen.

Testing Results: Round 1

  • Task 1: Navigate to the Routine screen & select Winding Down
    Result: 5/5
    Notes: 1. Testers were able to locate Routine in the tab bar & select the Winding Down routine.
    2. Tester 5 took little time to locate the routine in the tab bar, and each tester was able to select the winding down routine.
    Average time: 5-8 seconds
    Key Insight: Users were quick to check the tab bar for important locations.

  • Task 2: Update Reminder settings
    Result: 4/5
    Notes: 1. 4 testers were able to update the reminder settings in the Winding Down routine card.
    2. Tester 2 took time to update the sleep time & asked to align it like the rest of the parameters.
    Average time: 6-8 seconds
    Key Insight: Users were quick to complete the task, but 2 users, including tester 2, asked to align sleep time like the rest of the form fields.

  • Task 3: Create & accept a winding down routine
    Result: 5/5
    Notes: 1. All testers were able to go through the Winding Down routine.
    2. Tester 1 & 2 suggested including a checkbox to select and deselect steps in the routine as all steps are not widely applicable.
    Average time: 3-5 seconds
    Key Insight: Since all steps are not widely applicable, it’ll be nice to provide users with the option to pick steps that are applicable.

  • Task 4: Receive reminders & complete routine
    Result: 2/5
    Notes: 1. 3 testers were not able to complete the task.
    2. Tester 1,2,5 didn’t know if they were supposed to tap to expand reminders on the home screen. Tester 4 suggested including a label & percentage in the progress bar.
    Average time: 12 seconds
    Key Insight: 1. The User will need some kind of icon that clearly shows them that the reminder tile in the Dashboard will expand to a screen.
    2. The progress bar needs a label & progress percentage for better awareness of the routine stage.
    3. Include links to the articles listed on the reminder screen.

Design Prioritization Matrix: Round 2

After the 2nd round of usability tests, I again prioritized feedback on the Design Prioritization Matrix based on impact & efforts.

1. Align Sleep Time like the rest of the form fields on the routine screen.

2. Provide a checkbox option to select steps of the routine that are applicable in the winding-down routine screen.

3. Include an “arrow” icon to show that the reminder tile in the dashboard will expand to a screen.

    Average time: 5-8 seconds
    Key Insight: Users were quick to check the tab bar for important locations.

  • Task 2: Update Reminder settings
    Result: 4/5
    Notes: 1. 4 testers were able to update reminder settings in the Winding Down routine card.
    2. Tester 4 took time to update the sleep time & asked to align it like the rest of the parameters.
    Average time: 6-8 seconds
    Key Insight: Users were quick to complete the task, but 3 users asked to move “6 steps” to another location.

  • Task 3: Create & accept a winding down routine
    Result: 5/5
    Notes: 1. All testers were able to go through the Winding Down routine.
    2. Testers 1 & 2 suggested including a checkbox to select and deselect steps in the outline as all steps are not widely applicable.
    Average time: 3-5 seconds
    Key Insight: Since all steps are not widely applicable, it’ll be nice to provide users with the option to pick steps that are applicable.

  • Task 4: Receive reminders & complete routine
    Result: 3/5
    Notes: 1. 2 testers were not able to complete the task.
    2. Testers 1 & 5 didn’t know that there is a horizontal & vertical scroll in the Dashboard screen.
    Average time: 12 seconds
    Key Insight: 1. The User will need some kind of icon that clearly shows them that there is horizontal & vertical scroll in the Dashboard screen.
    Tester 4 suggested including a snooze functionality.
    Tester 3 asked to replace the arrow icon with an expand icon.
