Tactile Touch Technology for Multi-Finger Localized Interaction

Tianma NLT America (TNAM) (Santa Clara, CA) has announced the introduction of an LCD prototype with a tactile touch technology developed by NLT Technologies. This technology recreates the sense of tactile texture to the users by using electric vibrations and reproduces skin sensations as if they are tracing actual objects on the display. If multiple fingers touch the display at the same time, the digits on the area where the image is shown can feel the appropriate texture, but the digits on the area without the image will not feel the texture. This enables users to identify which area on a display the image is shown, not only visually, but also through tactile feel. The display provides:

  • Texture via skin sensation when the user traces the surface of the display where the image is shown.
  • Stimulus which can be localized in conjunction with the image object, enabling each finger to sense its own stimulus, so the display can accommodate multi-finger or multi-person tactile interaction with visual information.
  • Regional stimulation, which is provided by electrostatic force.
