Electronic device for collecting finger data and displaying a finger movement trace and related methods

摘要

An electronic device may include a finger sensor, a display, and a controller coupled to the finger sensor and the display. The controller may be configured to collect finger data from multiple portions of a user's finger as the user's finger is moved around on the finger sensor along a finger travel path. The controller may also be configured to generate on the display a finger movement trace corresponding to the finger movement travel path.
