Abstract: An example touch/pen (T/P) sensor device includes a T/P sensor to generate position information based on user interaction with a sensor surface of the T/P sensor, and a color sensor to sense a color hue of a writing tip of a pencil to be used to interact with the sensor surface of the T/P sensor to generate a digital image. The T/P sensor device also includes a processor to record metadata with the digital image to indicate the sensed color hue.

Abstract: An example of a flexible sensor stack includes a flexible film comprising a conformal polymer film or a flexible glass film. The flexible sensor stack includes first and second conformal poly(3,4-ethylenedioxythiophene) (PEDOT) films formed over the flexible film and including sensor traces to provide a flexible touch/pen (T/P) sensor surface, wherein the flexible sensor stack is bendable to conform to a non-flat attachment surface.

Abstract: In example implementations, a display is provided. The display includes a camera, a communication interface, and a processor. The camera is to capture a first image of a head-mounted device (HMD) wearable by a user. The communication interface is to receive pupil data from the HMD. The processor is communicatively coupled to the camera and the wireless communication interface. The processor is to determine abound of a field-of-view based on the first image of the HMD, track an eye of the user based on the field-of-view and the pupil data to determine a location of focus of the user, and move a second image to the location of focus on the display.
