I'm working with Myo. It's an armband which connects to the computer via Bluetooth. It can detect movement of hand and can detect several gestures, such as 'wave_left' , 'wave_right' , 'fingers_spread', 'fist' mainly. Now I've to write the Javascript so that disabled persons can navigate the website using Myo. To implement this, I want to map some key press events with Myo gestures.
wave_left => Tab
wave_right => Shift + Tab
fingers_spread => Backspace
fist => Enter
Now here's the code:
<script src='http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.6.0/underscore-min.js'></script>
<script src="https://cdn.rawgit.com/stolksdorf/myo.js/master/myo.js" ></script>
<script src="https://cdn.rawgit.com/stolksdorf/myo.js/master/experimental/myo.experimental.js" ></script>
Myo events are handled here like following:
var myo = Myo.create(0);
myo.on('arm_recognized', function(){
console.log('arm found!', this.id);
});
myo.on('arm_lost', function(){
console.log('arm lost', this.id);
});
myo.on('wave_left', function(){
console.log('wave Left!');
// Tab Key Press Event to be Triggered
});
myo.on('wave_right', function(){
console.log('wave Right!');
// Shift + Tab key Press Event to be Triggered
});
myo.on('fingers_spread', function(){
console.log('spread!');
// BackSpace key press to be triggered
});
myo.on('fist', function(){
console.log('fist');
// Enter key press to be triggered
});
myo.on('connected', function(){
});
myo.on('bluetooth_strength', function(BTS){
console.log(width);
});
myo.on('double_tap', function(){
console.log('double tap') ;
});
myo.on('gyroscope', function(data){
});
I've searched internet. For simulating Tab key press, people suggested to use $('some_element').next().focus() , but I want to get the native Tab key press. This post says it's not possible because of security issue. But the post is from 2009, and html5 has progressed a lot after then. Is it possible now to trigger keypress event of the special keys and get native result? If possible, what should I do?
