Augmented reality turns forearms into virtual keyboards

NEC Corporation has developed a device that uses smart glasses and augmented reality (AR) to turn the wearer’s arm into a virtual keyboard, allowing for contact-free operation. The device, named the ARmKeypad Air, could be used in a range of workplaces in the manufacturing, medical, security and distribution sectors.

In 2015, NEC introduced a trial model of the ARmKeypad, which combines smart glasses and a modified watch to turn the wearer’s arm into a virtual keyboard by recognising contact (vibration) operations.

The ARmKeypad Air takes this a step further by using AR, in combination with smart glasses, to create the image of a virtual keyboard on the wearer’s forearm. Unlike the existing ARmKeypad, the new technology enables contact-free operation through the movement of the wearer’s finger. This makes the technology ideal for sites where operations must be performed under sterilised conditions, free of direct contact with objects and clothes, etc. In addition, because there is no need for users to wear a watch, the ARmKeypad Air is suitable for situations in which wearing devices on the arm is not advisable, such as carrying out medical procedures.

“Moving forward, NEC will use the ARmKeypad and ARmKeypad Air to help improve workplace efficiency in sectors where hands-free operation is required, such as manufacturing, medicine, security and distribution,” said Yukio Maruyama, assistant general manager, System Integration & Services Market Division, NEC Corporation.

The company exhibited the ARmKeypad Air at the International Modern Hospital Show in Tokyo.
