Abstract
A thermoelectric display including an array of thermoelectric devices is used to provide output to a user in the form of thermal feedback. The thermal feedback may be used to provide navigation cues to the user to enable eyes-free navigation. The thermal feedback may be used to provide target acquisition cues to enable the user to accurately target a contact point on a touchscreen. The thermal feedback may be used to convey an emotive aspect of a message to the user. The thermal feedback may be used to identify to the user a caller associated with an incoming call. The thermoelectric display may be, alternatively or additionally, used to provide input to another device, such as a mobile device to which the thermoelectric display is operatively coupled.
