Passive haptics as reference for active haptics

Abstract:

An electronic device may include a housing (100), a display (102) disposed in the housing (100) and including an interface surface (112) arranged for user contact and a reference haptic (108). The interface surface (112) includes an active haptic output that provides a time-dependent haptic output and a reference haptic (108) disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output. The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device.
