Does the IR touch frame support multi-touch?

Yes, our IR touch frame hardware supports up to 40 simultaneous touch points. However, whether multi-touch works or if the frame is even functional depends entirely on the kernel configuration of your operating system:

Multi-touch Supported: Windows 7/8/10/11, mainstream Linux desktop distributions (like Ubuntu), and standard native Android systems support multi-touch out of the box, enabling seamless multi-user writing and gestures.
OS Limitations (Single-touch or Unresponsive):
1. Apple Systems (iOS / macOS): Due to Apple's ecosystem restrictions on third-party peripherals, external touch frames are treated as standard mice, meaning they only support single-touch mouse emulation, not native multi-touch gestures.
2. Customized/Stripped-down Android Systems (Important): Some customized Android builds designed for specific media players, kiosks, or industrial boards might have their touch configuration files (such as .idc files) omitted by the developer, causing the screen to only support single-touch. In more extreme cases, highly stripped-down Android kernels completely lack external USB touch drivers, which will result in the touch frame being completely unrecognized and unsupported.
