In an apparent effort to make using a touchscreen possible sans eyesight, Nokia has filed a patent application describing "slider inputs lids." Essentially, these lids would be placed onto a touchscreen to enable users to input certain commands without actually having to look at what's going on. For instance, a circular lid could give you easy access to volume, while a horizontal version could easily slide through music tracks or voicemail messages. The documentation points out that lids could contain a switch that would allow users to access a second set of user interface inputs "based on the position of the lid in relation to the touch sensitive area." Granted, this does seem like a stretch, but there's a hint of promise in there somewhere, we suppose.
