MIT Technology Review: Japanese researchers have been developing two different handheld devices that provide tactile data to the user. Both the Buru-Navi and Traxion systems use asymmetrical vibration to give the user the sensation of being pushed or pulled in a certain direction. In addition to being used in numerous applications such as navigation and gaming, the technology could help visually impaired people move around independently. Both devices will be demonstrated at the upcoming SIGGRAPH computer graphics conference in Vancouver, Canada.
