1 Sleep Beta Sleep tracking for adolescentsz Cameron Happer, Sean Nolan, Thomas Cunningham, Tae Lim Son Supervisors: Dr. Bernd Ploderer, Dr. Dhaval Vyas

2 Project Motivation & introduction Sleep is an essential role for a person s health and wellbeing. Sleep affects everyone, everyday With recent technologies, it s more easier to track and manage

3 Project Motivation & introduction Sean s Sleeping Patterns during this project

4 Problem the project tackles Use of computers, cell-phones and televisions at higher levels was associated with delayed sleep/wake schedules and wake lag, potentially impairing health and educational outcomes. In addressing pre-bedtime behaviour in adolescents, SleepBeta was designed to target the main issues of sleep deprivation in adolescents and provide ways to improve sleep. (2014) Adolescent Sleep Patterns and Night-Time Technology Use

5 Project Motivation & introduction Pre-bedtime behaviors are important to understand, as they are modifiable factors that may be relevant in addressing sleep problems in adolescents. Over 70% of adolescents are reported to use 2 or more electronic devices in their bedroom at night. Use of devices in bed a few nights per week or more was 46.8% cellphone, 38.5% computer, 23.2% TV, and 15.8% radio. Every night computer use was associated with short weekday sleep duration, and every night cellphone use was associated with wake lag (waking later on weekends).

6 Project summary Created by Zilu Liang Develop revised version of original system Improvements to back-end Full redesign of front-end and User Experience Field study in Semester 2

7 Semester 1 Planning Research current sleep tracking technologies and apps Research factors that affect sleep and the importance of sleep in adolescents Usability testing UI sketches, wireframes and mockups Submit ethics application Start development

8 Semester 2 Planning

9 Semester 2 Planning Complete ethics application Create Material Required to Run a short Field Trial/ Study Finish Development Recruit Participants Run a short 2 week study Write a final Document that discusses the method and the findings

10 Project actual progress Jan Researching Planning Developing Recruiting Field Trials Interviews Final Document Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

11 Problems & Our Solutions Acquiring the wearable devices Recruiting Participants Delays in Development Interview Consistency Data Consistency

12 Application Design ASP.Net Based application Hosted on an Azure Application Used the Open source Fitbit.Net Library

13 Before...

14 Usability Testing Design aesthetic felt too formal Looks like a business report Dull colours Lack of visual hierarchy Page layout needs improvements Bubble graphs confusing Legend could be simpler

15 Design/app goals 1. Awareness of sleep habits a. Do I get enough sleep? Am I oversleeping? 2. Understand how sleep can benefit wellbeing & performance a. daytime sleepiness, emotion/mood, focus etc. 3. Understand how factors (lifestyle choices) influence sleep a. relation between sleep & factors

16 After...

17 UI improvements Legends has two keys Good and bad (blue and red) Switch between graph views less overwhelming Bubbles have changed to tiles appear under each graph red means factor was bad for your sleep Blue good and white no effect Sleep diary form within the website Icons convey type of lifestyle factor the question is about

18 Research Study Preparation Using knowledge learnt from factors researched. Researching methods of information collection. Creating a interview 1 and guide. Creating interview 2 and guide.

19 Card sorting

20 Card sorting interview method layout cards with image facing up select 5 most important factors explain impact of each factor

21 Field study 3 weeks 4 participants Each were given a Fitbit to use Access to the SleepBeta website Filled in their daily questions tailored to lifestyle factors relevant to them

22 Field study results Post Study interview findings Rarely adolescents are enthusiastic about their sleep. In our case, one participant was interested and actively made changes to their lifestyle. Cards used in card sorting affected results slightly. Based on our results we came to the conclusion that adolescents don t care enough about sleep to actively improve it.

23 Conclusion Few errors/bugs. Field study results showed to move in a direction away from adolescents. Hand over the project to product creator. Advised changes to future studies based on our results.
