Looking for a low end solution that doesn't require expensive touch displays? Or want to try out Linchpin Touch before buying something?
Simply set up a Full HD display, connected to a computer fulfilling the requirements mentioned above. Then hook up a mouse, touchpad or trackball to your computer, but no keyboard. While not as intuitive as navigating by touch, this will work just fine with smaller displays. As a rule of thumb: The smaller your display, the easier it is to navigate by a mouse or other input device.
