Touch-sensitive device and method

摘要

Techniques are generally described for touch-sensitive devices with biometric information determination capabilities. The touch-sensitive device may include one or more of a transmitter, a receiver, and a processor. The transmitter may be configured to emit light towards a surface of the touch-sensitive device and the receiver may be configured to receive reflected light from a touch to the touch-sensitive device. The processor may be arranged to receive signals from the receiver and determines biometric information, and in some examples location of touch, based on the signals.

主权项

1. A touch sensitive device having spectroscopy components, the touch sensitive device comprising:
a display; a touch panel arranged to generate a signal responsive to a touch, wherein the display is viewable through the touch panel; a transmitter operable to transmit optical energy at a first wavelength to the touch panel, the first wavelength being useful for spectroscopically detecting an analyte; a receiver operable to receive optical energy reflected responsive to the touch; and a processor coupled to the receiver and arranged to analyze the reflected optical energy to determine, responsive to the touch and using spectroscopy, concentration of the analyte in blood determined from the reflected optical energy using chemometric algorithms.
