Patent number: 9669159Abstract: Example devices and methods of tongue stimulation for communication of information to a user are disclosed herein. In an example, a tongue stimulation device may include a body configured to be placed entirely within a mouth of the user and atop the tongue of the user. An array of electro-tactile elements may be distributed on the body, wherein each of the electro-tactile elements is configured to stimulate an area of the tongue adjacent the electro-tactile element. A wireless receiver coupled to the body may be configured to receive stimulation information wirelessly from outside the mouth of the user. At least one processing unit coupled to the body may be configured to transform the received stimulation information into a stimulation signal for each of the electro-tactile elements, and to provide the stimulation signals to the electro-tactile elements.Type: GrantFiled: April 2, 2015Date of Patent: June 6, 2017Assignee: Colorado State University Research FoundationInventors: John D. Williams, Joel A. Moritz, Charles S. Henry, Steven D. Floyd, Luke T. Van, Kendall Gurule, Jaclyn A. Adkins, Matthew J. Swigart, Travis S. Bailey, Leslie M. Stone-Roy
