Abstract

An apparatus, method, and medium for outputting tactile feedback on a display device are provided. The apparatus includes a controller obtaining movement information of two or more vibration devices provided at edges of a vibration panel, and a vibrator vibrating the two or more vibration devices with a predetermined phase difference with a target contact location set as the vibration center point, the target contact location corresponding to a location where information on tactile feedback is to be output, based on the movement information obtained by the controller.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0119309 filed in the Korean Intellectual Property Office on Nov. 29, 2006, which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments relate to an apparatus, method and medium for outputting haptic feedback on a display device. More specifically, the embodiments relate to an apparatus, method, and medium for outputting tactile feedback on a display device, by which feedback to a user's tactile sense input to an image display device can be transmitted To identify the location currently indicated by the user, and the device, method and medium can notify or inform the user of the location of the user's fingertip. Background technique [0003] In general, haptic technologies are classified into force feedback using kinesthetic information, haptic feedback using haptic information, and thermal feedback using thermal information. Prior art typically provides peo...
