If you have several devices that might be remotely controlled via smartphone with different apps, that might be messy switching things up. Tapdo is a fingerprint-reading gadget that simultaneously controls all devices, by assigning different parts of your fingers to different actions. It communicates by Bluetooth with a dedicated special app, that runs various other device-controlling apps already on the phone. It can also control functions of the phone itself.
For the first time the app is used to assign specific actions to specific fingerprint areas on the underside of the user’s hand. This allows user to tap the pad of their index finger to play or pause music on a player, while tapping the middle section of the finger could increase the volume, and bottom – could switch to the next track.
Different fingers could be assigned to different devices. While the index finger could be used to control a music player, the middle finger could control the lamp, and the third finger could be used to open the doors. The technology is demonstrated in the following video.
