Abstract:
Finger motion tracking from unobtrusive inertial measurement unit (IMU) methods, such as smart rings and smart watches, is becoming increasingly useful as adoption of wearables become ubiquitous. Its applications range from better evaluations of a patient’s motor skills to real-time sign language translation. This paper explores two different methods for finger motion tracking—a hidden markov model (HMM) and a long short-term model (LSTM)—of the index finger metacarpophalangeal (MCP) and Interphalangeal Proximal (PIP) joints relative to the wrist using accelerometer data to predict relative position and discusses the tradeoffs of both methods. In order to overcome the challenge of limited IMU data, a synthetic IMU data preparation method was also explored.
