You only need one finger to play on the Tuttuki Bako, a toy game box available in Japan. Stick your finger in the hole on the side and a digital replica of your digit is then displayed. You can then wriggle your finger and play with a panda, watch the digital digit touch a girl’s face or use it to explore a lake. There is no simulation involved when touching the digital images.
The Tuttuki Bako is battery operated and costs $30. It is (so far) only supplied in Japan by toymaker Bandai.
