This gesture is activated after closing the active hand. This gesture resembles the action of clicking the mouse.

Let’s see a simple example to understand how it works!

We are going to create a simple application which changes the text on the screen when an GRIP action is captured by the sensors.

In order to trigger the function from Javascript we are going to create a message called “msg” in the HTML code, this by default is set to show on the top left of  the screen the text ‘Awaiting to be gripped’ and will change when GRIP is captured by the sensors.

The text in blue shows the line added onto the HTML code:




     <h1 id="msg">Awaiting to be gripped!</h1>
  <canvas id="skeletonsCanvas" width="640" height="480"></canvas>



Now, within the grip function on JAVASCRIPT we are going to add the line which calls “msg” created on the HTML code, and will show on the screen the message “GRIP triggered succesfully!” when a grip action is captured by the sensors.


function grip() {
  console.debug('Grip! :)');
  document.getElementById("msg").innerHTML = "GRIP triggered successfully!";

If you are not using the uboxPlayer on the PC with the Kinect sensor you can test it out on the web. For doing so, open the following link, right click on the mouse and select “New User” from the dropdown menu. It will change as mentioned.
