Other features include the ability to project through glass up to five millimetres thick, a bezel-free design and support for up to 80 simultaneous touch points for a more natural multi-user interactive experience. The system supports palm rejection, with a response of under 10 msec.
This technology overcomes design and optical challenges found in other PCT solutions by utilising advanced optical modelling techniques developed in 30 years work by 3M; the result, says the company, is a sensor designed to work universally on 2K and 4K applications across a range of sizes, including planar (curved) screens, while maintaining high image quality and touch responsiveness.
This technology minimises Moiré and sparkle –problems known in other PCAP systems – and offers both equipment manufacturers and display integrators a more durable, scalable and easy-to-integrate, Multi-Touch System that can be customised to meet customer-specific applications.
Systems can be configured for displays ranging in size from 15 to 65 inches and are designed for a broad range of commercial display applications, including digital signage, regulated gaming, retail, automotive showrooms, public venues, museums and hospitality. One standard protocol is required for all sizes, making it easy to interface with different operating platforms - Windows, Linux, OSX and Android – regardless of system size.
“Our new sensor technology, based on proprietary ultrafine metal mesh design, allows developers and integrators to take a piece of glass and turn it into an exciting multi-touch and real multi-user customer experience,” says Paolo Pedrazzoli, marketing operations manager, 3M Touch Systems EMEA. “This advanced technology builds on our existing and established range of PCAP multi-touch systems, which have been meeting the needs of system designers and users in various industries and applications for years.”
