Lenovo Yxx0 laptops have a touch inductive panel http://www.gigamark.com/images/stories/8/Lenovo_y550/Untitled-4.jpg contains the pretty cool navigation slidebar http://www.fcenter.ru/img/article/notebooks/Lenovo_IdeaPad_Y550P/152399.jpg
How SlideNav should work:
User assign applications to the numbers. When user want to launch one of them, he touch slidenav in any place (touch but did not raise finger), after that driver show applications list on the screen http://www.fcenter.ru/img/article/notebooks/Lenovo_IdeaPad_Y550P/152341.jpg User move finger to the lift or to the right, until needed application was selected on the screen. When apllication selected user raise finger and this application get started.
I tried use tp-smapi-dkms for detect slidenav buttons, but it's not work for me with error: No such device.
Even if I was able to detect slidenav buttons it's not enough - there need a program that works like an official Lenovo driver (show applications list when user touch panel).
