Design Analysis

Operational Objectives:

Must Haves:

• Device must be able to detect tics and differentiate tics/involuntary movements from intentional actions

• Secure data transfer between device and its related app (personal medical privacy/HIPPA)

Wants: (operational objective weight 1-10)

• (3) Lightweight/non intrusive wearable (sizing of device)

• (5) Make the device easily securable and removable from end user

• (7) Open source/low cost device and app to provide user accessibility to all markets

• (8) Software learns to detect tics better over time thru user denotation and other tools

• (6) Hyperextended battery life [day/multiday]

After completing the KT design and evaluation matrices we have determined that although wiring our devices is the most secure way of moving sensitive data such as medical device data, it has its own set of issues that can be solved by looking at our alternatives. In this case wifi which is WPA2/WPA3 (wifi 6 where able) secure.

In addition, having completed the same process for the different methods of physically attaching the sensor array and head unit to the user we determined that velcro was the best alternative. After an evaluation of the alternatives to velcro we found that perhaps multiple options can be pursued as medical tape seemed a close second. Additionally both medical tape and velcro have been seen in similar use cases throughout the medical industry to great effect.
