Glove Based Wearable Controller 2 P 18001 Natasha Amadasun (BME), Adrita Arefin (CE), Christopher Atras (CE), Corey Barrows (IE), Joseph Di. Passio (EE), Zach Hankinson (ME) Rochester Institute of Technology The system architecture describes the overall inner workings of the functionality of the glove based wearable controller. Project Summary • Computers and phones require very present in-depth interaction. • Leads to more distraction and usually takes full attention to properly respond to notifications. • Project aims to provide users with a convenient, reliable device with qualitative proof that a wearable, glove based interface can adequately replicate response speeds and normal functionality of a computer or mobile phone. Figure 2. System Architecture Mechanical The mechanical design of the prototype consists of a durable case, a printed circuit board, silicone straps, and other miscellaneous components. Requirements • Customer Requirements – No distraction, usable without looking at touchscreen – Ability to use interface quickly – Hassle free Bluetooth connectivity – Little delay, real time processing – Long battery life, safe energy dissipation – Aesthetically pleasing, low profile – No restriction from other actions – Light Weight, long lasting, water resistant – “One size fits all” – Full keyboard functionality – Android, i. OS & laptop compatible – Hand tracking functionality for gesture control • Engineering Requirements – Miniscule communication delay (Target value: 180 ms) – Strong Bluetooth connection/signal strength (Target value: On) – Long battery life (Target value: 24 hrs) – Reasonable rate of energy dissipation (Target value: 20 m. W) – Range of finger movement (Target value: 120 degree) – Compact, lightweight, adjustable (Target value: 50 g) – Long comfortable length of wear (Target value: 18 hrs) – Large number of actuations before failure (Target value: 1, 000) – High drop height without failure (Target value: 2 m) – Large range of gestures recognized (Target value: 50) – High number of compatible device types (Target value: 5) Overview of Design The functional decomposition chart defines the main use case scenario by labeling the functions and sub-functions of the project.
