Neonode's zForce is an infrared touch technology designed to be used on devices from smart-phones to home appliances. With this optical 2D touch technology, input isn't limited to using your fingers, but any type of material will work. The zForce touch-screens can also be adapted to any type of surface regardless of shape. For those interested in this neat touch-screen technology, check out Neonode.com.
With the Linux 3.13 kernel input driver updates, there's now a Neonode zForce driver. The Linux kernel driver for the touch-screen was originally presented in August as about one thousand lines of new kernel code. The driver ends up being the "zforce_ts" kernel module and the work appears to be done by MundoReader and Barnes & Noble.
The other work for the Linux 3.13 kernel input area includes a Hyper-V synthetic keyboard driver and various bug-fixes and clean-ups. More details on the Linux 3.13 input changes can be found via the Git merge.
