See the [HTML 5 DeviceOrientation Specification]( * http://www.w3.org/TR/orientation-event/) for more details. * * Many new computers, and especially mobile phones * and tablets, provide hardware support for device orientation. Web * developers targeting mobile devices will be especially interested in this * class. * * Device orientation data are relative to a common starting point. For mobile * devices, the starting point is to lay your phone face up on a table with the * top of the phone pointing north. This represents the zero state. All * angles are then relative to this state. For computers, it is the same except * the screen is open at 90 degrees. * * Device orientation is reported as three angles - `alpha`, `beta`, and * `gamma` - relative to the starting position along the three planar axes X, Y * and Z. The X axis runs from the left edge to the right edge through the * middle of the device. Similarly, the Y axis runs from the bottom to the top * of the device through the middle. The Z axis runs from the back to the front * through the middle. In the starting position, the X axis points to the * right, the Y axis points away from you and the Z axis points straight up * from the device lying flat. * * The three angles representing the device orientation are relative to the * three axes. `alpha` indicates how much the device has been rotated around the * Z axis, which is commonly interpreted as the compass heading (see note * below). `beta` indicates how much the device has been rotated around the X * axis, or how much it is tilted from front to back. `gamma` indicates how * much the device has been rotated around the Y axis, or how much it is tilted * from left to right. * * For most browsers, the `alpha` value returns the compass heading so if the * device points north, it will be 0. With Safari on iOS, the 0 value of * `alpha` is calculated from when device orientation was first requested. * ol.DeviceOrientation provides the `heading` property which normalizes this * behavior across all browsers for you. * * It is important to note that the HTML 5 DeviceOrientation specification * indicates that `alpha`, `beta` and `gamma` are in degrees while the * equivalent properties in ol.DeviceOrientation are in radians for consistency * with all other uses of angles throughout OpenLayers. * * @see http://www.w3.org/TR/orientation-event/ * * To get notified of device orientation changes, register a listener for the * generic `change` event on your `ol.DeviceOrientation` instance. * * @constructor * @extends {ol.Object} * @param {olx.DeviceOrientationOptions=} opt_options Options. * @api */ ol.DeviceOrientation = function(opt_options) {   goog.base(this);   var options = opt_options ? opt_options : {};   /** * @private * @type {goog.events.Key} */ this.listenerKey_ = null;   goog.events.listen(this, ol.Object.getChangeEventType(ol.DeviceOrientationProperty.TRACKING), this.handleTrackingChanged_, false, this);   this.setTracking(options.tracking !== undefined ? options.tracking : false);   }; goog.inherits(ol.DeviceOrientation, ol.Object);     /** * @inheritDoc */ ol.DeviceOrientation.prototype.disposeInternal = function() { this.setTracking(false); goog.base(this, 'disposeInternal'); };     /** * @private * @param {goog.events.BrowserEvent} browserEvent Event. */ ol.DeviceOrientation.prototype.orientationChange_ = function(browserEvent) { var event = /** @type {DeviceOrientationEvent} */ (browserEvent.getBrowserEvent()); if (event.alpha !== null) { var alpha = ol.math.toRadians(event.alpha); this.set(ol.DeviceOrientationProperty.ALPHA, alpha); // event.absolute is undefined in iOS. if (goog.isBoolean(event.absolute) && event.absolute) { this.set(ol.DeviceOrientationProperty.HEADING, alpha); } else if (goog.isNumber(event.webkitCompassHeading) && event.webkitCompassAccuracy != -1) { var heading = ol.math.toRadians(event.webkitCompassHeading); this.set(ol.DeviceOrientationProperty.HEADING, heading); } } if (event.beta !== null) { this.set(ol.DeviceOrientationProperty.BETA, ol.math.toRadians(event.beta)); } if (event.gamma !== null) { this.set(ol.DeviceOrientationProperty.GAMMA, ol.math.toRadians(event.gamma)); } this.changed(); };     /** * Rotation around the device z-axis (in radians). * @return {number|undefined} The euler angle in radians of the device from the * standard Z axis. * @observable * @api */ ol.DeviceOrientation.prototype.getAlpha = function() { return /** @type {number|undefined} */ ( this.get(ol.DeviceOrientationProperty.ALPHA)); };     /** * Rotation around the device x-axis (in radians). * @return {number|undefined} The euler angle in radians of the device from the * planar X axis. * @observable * @api */ ol.DeviceOrientation.prototype.getBeta = function() { return /** @type {number|undefined} */ ( this.get(ol.DeviceOrientationProperty.BETA)); };     /** * Rotation around the device y-axis (in radians). * @return {number|undefined} The euler angle in radians of the device from the * planar Y axis. * @observable * @api */ ol.DeviceOrientation.prototype.getGamma = function() { return /** @type {number|undefined} */ ( this.get(ol.DeviceOrientationProperty.GAMMA)); };     /** * The heading of the device relative to north (in radians). * @return {number|undefined} The heading of the device relative to north, in * radians, normalizing for different browser behavior. * @observable * @api */ ol.DeviceOrientation.prototype.getHeading = function() { return /** @type {number|undefined} */ ( this.get(ol.DeviceOrientationProperty.HEADING)); };     /** * Determine if orientation is being tracked. * @return {boolean} Changes in device orientation are being tracked. * @observable * @api */ ol.DeviceOrientation.prototype.getTracking = function() { return /** @type {boolean} */ ( this.get(ol.DeviceOrientationProperty.TRACKING)); };     /** * @private */ ol.DeviceOrientation.prototype.handleTrackingChanged_ = function() { Iif (ol.has.DEVICE_ORIENTATION) { var tracking = this.getTracking(); if (tracking && !this.listenerKey_) { this.listenerKey_ = goog.events.listen(goog.global, 'deviceorientation', this.orientationChange_, false, this); } else if (!tracking && this.listenerKey_) { goog.events.unlistenByKey(this.listenerKey_); this.listenerKey_ = null; } } };     /** * Enable or disable tracking of device orientation events. * @param {boolean} tracking The status of tracking changes to alpha, beta and * gamma.
