Abstract
Examples are provided for measuring force applied to a device, such as a stylus tip. An example stylus includes a stylus body, a stylus tip, and the stylus tip including a light emitting device and a compressible light reflecting optic, the light emitting device comprising a light emitter and a light detector, and the compressible light reflecting optic comprising a first reflective layer configured to (i) allow a first portion of light from the light emitting device to pass and (ii) to reflect a second portion of light from the light emitting device, and a second reflective layer, more reflective than the first reflective layer, configured to reflect light from the light emitting device, the first layer being spaced from the second layer by a light-transmissive material. A force exerted on the stylus tip is measurable based at least on a parameter of light received at the light detector.
