Patent attributes
Provided is a gesture-recognition (GR) device that includes a printed circuit board (PCB) and a controller. The circuit board has an aspect ratio exceeding a threshold value that corresponds to at least a 70 percent difference between length and width of the PCB. The PCB includes a first unit and a second unit. The first unit corresponds to a base unit to be grasped by hand of a user. The second unit corresponds to an elongate unit that extends outward from the first unit. The second unit is characterized by a minimal wand form factor. A rigid strength of the second unit is based on at least a shape of an outer shell and a structural attribute of the second unit. The controller controls illumination of a plurality of light sources mounted on the second unit of the circuit board based on assertion signals.
