MULTICOLOR BIOMETRIC SCANNING USER INTERFACE

摘要

A mobile computing device may include a biometric sensor in proximity with a color-controlled layer. Where the color of the color-controlled layer may be changed, a processor of the mobile computing device may control the color of the color-controlled layer responsive to sensing various conditions. For example, the color of the color-controlled layer may be controlled, by default, to match the housing of the mobile computing device. Responsive to sensing an approaching user finger, the color-controlled layer may be controlled to change color. The color-controlled layer may be controlled to change color again upon contact of the finger, upon removal of the finger and upon determining authentication success. The color-controlled layer may be structured as a mix of heating elements and thermochromic polymer elements.

主权项

1. A method of changing a perceptible color of a biometric sensor in a computing device, the computing device including a surface surrounding the biometric sensor, the surface having a color, the method comprising:
controlling a current flow provided to a color-controlled layer positioned under the biometric sensor such that the perceptible color of the biometric sensor is an initial color and the initial color approximates the color of the surface.
