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

Sean’s Sleeping Patterns during this project
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
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).

Problems & Our Solutions
● Acquiring the wearable devices
● Recruiting Participants
● Delays in Development
● Interview Consistency
● Data Consistency
Application Design
● ASP.Net Based application
● Hosted on an Azure Application
● Used the Open source Fitbit.Net Library
Before...
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
Design/app goals
1. Awareness of sleep habitsa. Do I get enough sleep? Am I oversleeping?
2. Understand how sleep can benefit wellbeing & performancea. daytime sleepiness, emotion/mood, focus etc.
3. Understand how factors (lifestyle choices) influence sleepa. relation between sleep & factors
After...
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
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.
Card sorting
Card sorting
● interview method● layout cards with image
facing up● select 5 most important
factors● explain impact of each factor
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
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.
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.
