Japanese gadget maker Elecom has announced the TK-TCT005BK [JP], a combination of a numeric keyboard for notebooks and touchpad supporting gestures. You can switch between both functions by pressing the “Num” button on the top left of the device.
The touchpad lets you zoom in and out by using your fingers (see the graphic below). However, the USB device only works with Windows PCs.
