Acknowledgment
Wrist-worn devices are the most common form factor of wearable computers currently in use. Despite the large popularity of the wrist-worn wearables as commercial devices (Fitbit, Apple watch, Android Wear), little research has been done to explore their applications for special education. Due to their small dimensions and unobtrusiveness, wrist-worn wearables, combining mobile and wearable (M&W) technologies, have a large potential to help students with intellectual disabilities, supporting interpersonal collaboration and their assistant staff in class. To explore how wrist-worn applications can help in special education, we employed user-centered design techniques to elicit the application needs and system requirements, and developed a wearable application to assist students in class.
Abstract
Background
Methods and Process
• Continue to develop this assistive application for special education in class
• Test this demo with students and staff in the scenario of special education in class
• Refine the requirements, design and UI according to the feedback of the tests
• Extend the application to include off-class functions as well
• Survey the students’ preference of design style and UI on the wearable
• Explore the usage off the watch sensors• Test the design for robustness, scalability and
feasibility
Ongoing and Future work
The special education setting: Mason Life (masonlife.gmu.edu/) is an innovative post-secondary program for young adults with intellectual and developmental disabilities who desire a university experience in a supportive academic environment.

M&W Assistive Application
In Class RequirementsMediate student mood (anxious, bored) and behavior (sleepy,
agitated)Maintain student attention and alertness for focus and
communicationCoordinate a presentation moderation of a seminar
Coordinate student collaboration in group for interpersonal communication
Present a countdown towards the end of class: snack break, question, lunch
Moderate student questions: timing, relevancy, frequencyProvide a reward, or incentive to reinforce a good behavior
