Smart Workout Assistant

Worked as a part of a team to develop a smart workout assistant for my capstone project. Developed a smart mirror that monitors exercise form in real time and provides visual feedback. Additionally the system is designed to be inclusive for all heighs, standing and seated exercises adjusting the screen height via an actuator for optimal user experience. This project was built around a Microsoft Kinect sensor for user motion tracking collecting joint data. This joint movement data was then used to train a machine learning model for optimal and incorrect form which could be identified in real time. This data is presented to the user through color coded visual feedback monitoring their form in x,y,z planes also accounting for the depth aspect. The machine learning model was developed in Turi. Software development was primarily done in C# and C for the Arduino and actuator controol.

Leap Motion

Programmed a LEAP Motion controller to serve as the navigtion controls for a Crazyflie quadcopter. Based upon the project from the Deloitte Tech Exchange, developed the idea with practical implementations in the form of controlling quadcopter navigation through hand movements. Developed an natural and intuitive interface with the LEAP Motion controller to allow natural control of a quadcopter, with simple hand gestures. Primarily programmed in Python. Worked with the LEAP Motion SDK to map hand gestures in 3D space with the flight controls with each of the three axes corresponding to different navigation control attributes, such as the yaw, roll and pitch.

You Eye

Hack The North

YouEye monitors the visual environment straight ahead and sends descriptive visual speech guidance to the user informing the user exactly what the obstacle is and its distance from the user. As the user is walking, the camera constantly takes screenshots ahead which are analyzed through google-visualization to identify the obstacle in the screenshots. The distance and description of the object are then sent back to the user as speech feedback in real time. Depending on the distance of the object, YouEye would give different warning or feedback. If the object is 5 meters away, YouEye would inform the user the pathway is all clear. As the distance of the object ahead decreases below 5 meters, the feedback message escalates from caution and finally warning message while providing the description of the obstacle and its distance away from the user. This way, the user is well aware of their surroundings to make more accurate judgments of their actions when they are traveling anywhere, anytime.
