For more information, read Paul Miller's article (Engadget), Stantum's mind-blowing multitouch interface on video!
Paul Miller says:
"The PMatrix multitouch firmware allows for unlimited inputs, detection of any contacting object (a finger, a stylus or even a paintbrush) and pressure sensitivity. We played with the demo unit for a bit and were frankly blown away, it's far and away the best touch experience we've ever seen or felt, and the multitouch functionality is just gravy on top. Stantum is targeting resistive touchscreens because they're still considerably cheaper to build than capacitive ones, and from our perspective there seems to be zero tradeoff -- for sensitivity and accuracy this destroys everything else we've seen on the market, capacitive or not."
How it works: Tech Specs from Stantum:
PMatrix: The unparalleled Multi-Touch IP core and detection firmware (pdf)
"PMatrix™ is the most powerful software engine for Multi-Touch technology. It runs as a chip firmware or software on controllers orany embedded processing devices. PMatrix scans and delivers an exact representation of what’s happening on the touch-panel. The Multi-Touch driver dynamically updates the cursor list, enabling any application to control the Graphical User Interface objects."
Stantum's rational behind the company's choice of using resistive rather than capacitive touch technology:
Why resistive? :
In comparison to capacitive sensing, resistive technology brings :
• Versatility : it detects fingers, gloves, stylus and any contact object
• A lower solution cost
• Lower power consumption
• Faster scanning rate
• Lower overall latency
• Precision is linear (same in the center and at the borders)
• Performance is not affected by the size of the touch-panel or the number of touches
• Transparency and soft touch enabling user experience equivalent to the best capacitive touch-panels
I'll update this post when I have more information!
