Abstract
A touch device in spherical or other curved form includes a hollow spherical casing and at least one touch sensing layer. The spherical casing includes an inner surface and an outer surface, the touch sensing layer is attached to the inner surface of the spherical casing, the touch sensing layer includes a core portion and a touch portion. The touch portion extends and diverges outwardly from the core portion. The touch portion comprises a plurality of sub-touch portions, an area of each sub-touch portion is greater than an area of the core portion. The disclosure also includes a curved non-spherical touch device.
Claims14
