Abstract
Acoustic touch apparatus comprising a substrate having first and second surfaces capable of propagating surface acoustic waves, the second surface comprising a touch region and the first and second surfaces coupled via a rounded connecting surface; at least one acoustic wave transducer on the first surface; and at least one reflective array on the first surface. The transducer is capable of transmitting or receiving waves to and from the reflective array. The substrate and reflective array can acoustically couple waves between the first and second surfaces. The substrate has a border region on the first surface adapted to hide the transducer and reflective array and preclude distortion of waves propagating over a window in the border region. The border region may have a border layer except at the window and a corrective lens is used proximate the window, or the border region comprises discolored glass except at the window.
