Tactile guidance system for touch screen interaction

摘要

A mobile computing device includes a housing portion defining a front face and a substantial planar back face that is opposed to and directed away from the front face. The device also includes a touch screen input mechanism arranged on the front face and a plurality of tactile guides on the back face. Program code is stored and executable on the device so that, when the code is executed, it identifies a contact input area on the touch screen, where a user can make selections on the touch screen, as being aligned with one of the plurality of tactile structures.
