js & reading sensors on MS surface pro 2 tablet

Hi all,

I've never used js in Max in all these years...not sure why now that I looked over the docs! Quite useful.

Anyhoo...I have an MS surface pro 2 tablet. Lots of built in sensors and one of the ways you can access the data is via java script. I knew it was wishful thinking, but couldn't get it work in Max. I am assuming it's because the calls made in the code are outside the standard js library... at least that's my guess. Here's my js code:

inlets = 1;
outlets = 4;

// bang -- start data stream

function bang()
{
   var sensor = Windows.Devices.Sensors.OrientationSensor.getDefault();
    if (sensor) {
        // Select a report interval that works for the app and that the sensor supports.
        var minimumReportInterval = sensor.minimumReportInterval;
        var reportInterval = minimumReportInterval > 20 ? minimumReportInterval : 20;

        // Set the report interval to enable the sensor for polling
        sensor.reportInterval = reportInterval;

        var reading = sensor.getCurrentReading();
        if (reading) {
            var quaternion = reading.quaternion;
            var x = quaternion.x;
            var y = quaternion.y;
            var z = quaternion.z;
            var w = quaternion.w;
            
            // output values
            outlet(0, x);
            outlet(1, y);
            outlet(2, z);
            outlet(3, w);
        }
    }
}

It gives an error: js: orientation-sensor-read-test.js: Javascript ReferenceError: Windows is not defined, line 11

So my question is: is there a way to extend the js library to include whatever is needed to accomplish what I want to above? There are also other potential paths (c++, c#, vb), but my non-max programming stopped at Fortran77 :)

Here's the link to the reference (first link contains the code I'm using above, second link is MS' ref page:

Thanks in advance for any nudges in the right direction.

Cheers,
