Now here’s a curious project: an invisible touchpad built into a keyboard. When you need to type, you can use Moky to lash out the words at a fast rate; then it becomes a large optical touch pad, using infrared sensors.
It means an end to having to carry a separate mouse and keyboard for your tablet, mobile phone or laptop, saving you space in your bag and hassle for frequent travellers.
It connects to your device using Bluetooth low energy, and even supports multitouch. It works with Windows, Mac and Android, but bad news for iPhone users: only the keyboard function is supported.
