5 point multitouch12/16/2023 However, this does rely on the ability of the device to switch into multi-touch mode when these requests are received. Most multi-touch devices, when they receive these requests, will switch into multi-touch mode if they have defaulted to single touch mode.įortunately, our driver can also determine if a device is multi-touch capable and will send the same USB multi-touch requests, irrespective of operating system, hence we can induce multi-touch functionality in all OS that we support. of contacts it supports and to enter multi-touch mode. The native touch drivers in Windows 7 and above can determine that a device is multi-touch capable and will send USB requests to establish the maximum no. When running in single mode the touch screen has a better chance of functioning correctly in non multi-touch aware systems than if it sends out multi-touch data hence the dual mode capability. Other multi-touch devices will operate in single touch mode unless they receive a request from the OS to enter multi-touch mode so although they are multi-touch devices they can in some cases default to running in single touch mode. Windows 7 and above) and will always operate in multi-touch mode and are not aimed at non multi-touch aware operating systems such as MacOS, CE, Solaris, some Linux distributions. We are not too sure what you might do with 100 simultaneous touches but if you need it, its available!įor the purposes of this document multi-touch will now refer to any device that supports more than 1 touch.Ĭautionary note: Some multi-touch devices are aimed solely at multi-touch aware operating systems (e.g. True multi-touch devices tend to offer 5 to 10 touch support but some technologies now offer much greater multi-touch capabilities. For example our Mac driver supports the 2 to 5 finger gesture range implemented in MacOSX so you could not invoke 3,4,5 finger gestures with a dual touch device. Dual touch systems are often advertised as 'multi-touch' but of course would not be useful if your usage requires more than 2 touches.ĭual touch systems can support many of the widely used gestures such as pinch, zoom, rotate, 2 finger scroll but of course cannot be used for any gestures requiring more than 2 touches. The most obvious requirement in supporting multi-touch is that the touch device in use physically supports multi-touch and is capable of transmitting independent touch data per stylus to waiting drivers.īroadly speaking touch devices either offer single, dual or multi-touch functionality. These are the multi-touch issues to consider. "can I get multi-touch in a browser under MacOS?", read on. "Can I move more than one fader at a time on my DAW system" "I have multi-touch when I run my application in Windows but not MacOS?" "will my application work with multiple touches?" However, this does not really answer the question fully, especially as often the real question is. Simple question with an apparently simple answer, 'Yes'. One of the most often asked questions is 'do your drivers support multi-touch?'.
