Atlanta, Georgia
June 2014 – June 2019
- Ph.D. with a focus on multimodal Tongue drive system (mTDS), a next-generation human-computer interaction system for the people with tetraplegia which incorporates multiple remaining abilities such as speech recognition, tongue, and head motion to control computers, smartphones, wheelchair, and so forth.
- Developed ARM M4, CC251X, and CC254X based firmware for multi-sensor (magnetometers, accelerometer, and gyroscope) communication to find user gestures (tongue, head movements) as commands. Wireless interfaces (BLE, RF) for seamless interaction with devices.
- Developed SVM based algorithm to process tongue gesture in the wearable unit (ARM, CC2510) and Kalman filter based sensor fusion algorithm for head tracking.
- Developed touchscreen UIs (Qt-based) for ARM A8 (Beaglebone Black) to train tongue commands using machine learning algorithm and an option to switch between devices under control. Also, designed human experiments to evaluate user interaction efficacy with computers, smartphones, and wheelchair. Also involved in collecting experimental data and statistical analysis.
- Involved in electronic systems and PCB design (wearable unit, wheelchair, and PC interfaces), debugging, and testing.
