The Twiddler is a chorded keyboard and mouse allowing one to type with a single hand.[1]
History
The first Twiddler was launched in 1992 by the HandyKey Corporation.[2] HandyKey was purchased in 2007 by the Canadian firm Tek Gear.[3]
Specification
The original Twiddler used a serial port for communication and a PC AT keyboard port for power.[4] This was replaced with USB for the Twiddler 2.[5] The third generation Twiddler, the Twiddler 3, natively communicates using USB or Bluetooth and provides haptic feedback through an optionally installed module.[6] The fourth generation, the Twiddler 4, announced in 2024, will use USB-C or Bluetooth, and replaces the Twiddler 3's joystick with an optical trackpad.[7]
