Earlier today, Synaptics announced its SmartBar technology that adds a touch input area -- enabled by a sub-0.2mm-thick PET film -- onto the space bar, which then lets you perform certain tasks without having to touch the mouse or trackpad. We went over to the company's show room at Computex to check this out, and we came away impressed. In the first demo, we looked at how you can quickly select text while typing by simply swiping to the left on the space bar. We were then shown how you can scroll with two fingers on the space bar: hold down one on the left and swipe with another on the right for vertical scrolling, and vice versa for horizontal scrolling. This will take some getting used to, obviously. You can also zoom in and out by swiping both fingers inwards or outwards -- a bit like pinch-to-zoom but on a space bar.
