Virtual Keypad
Use your smartphone as a keypad to respond from any distance. Just point your smartphone camera at the QR code below, and click the pop-up window that appears on your smartphone.
Programmers: From within an online experiment (such as one
created using
PsychoJS
or lab.js), initiate an appropriate
Receiver to provide the participant with a unique QR
code. Use this Receiver object throughout the experiment
to update keypad parameters or provide messages to the participant -
bidirectional communication between the Receiver and
Keypad allows for trial-by-trial adjustment of font and
alphabet.
