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.
