Traditionally "desktop" browsers haven't always supported touch events, but as far as I remember Firefox on desktop supports it (in Windows 7 with a touch-enabled screen - like on tablet devices). Opera for desktop doesn't currently, but as an interesting aside I've seen that the Opera Mobile Emulator (used to test our mobile browser in a desktop environment) responds to MacBook multitouch on the touchpad. > ?? can voice commands be mapped to 'touch' commands. > ?? is it up to the author to ensure that the keyboard and/or mouse > controls are mapped to touch events In mobile browsers, there's usually a built-in mapping that translates a touch to a series of mouse events. Generally though, this only applies to single-touch, and only to individual clicks - a tap on the screen fires the various focus/click events, but the browser doesn't "track" a touch, nor does it fire any mousemove equivalents. To actually react to single-finger movement on the screen, and definitely for multitouch, developers need to specifically change their code to track touchstart/touchmove/touchend events. > ?? is this another javascript black hole that the browser knows nothing about. > > we will need to review Guideline 2 Keyboard to make sure this stuff is covered. -- Patrick H.
