Abstract
A mobile device having a HOME button with integrated user biometric sensing comprises a casing, a touchscreen, a HOME button and a camera/scanner module. The touchscreen is mounted on the casing and simultaneously acts as a display panel and a touch-sensitive digitizing input pad. The HOME button is mounted on the casing, and at least a portion of the HOME button is formed of an optically transparent material forming an aperture or lens for transmitting optical images through the HOME button. The camera/scanner module is disposed below the HOME button adjacent the aperture, and includes a housing, a lens, a photo sensor and signal wires which operatively connect the scanner/camera module to sensing/security circuitry disposed within the casing. When a user presses the HOME button with a fingertip, the lens array focuses an image of a fingerprint from the top surface of the HOME button onto the photo sensor.
