The current InfiniTouch controller outputs data at 13-bit resolution (8192 points) each for X and Y, and 8-bit resolution (256 values) for force. The InfiniTouch controller supports communications with a host PC via either USB or an EIA-232 serial port. Windows drivers are available which interface with the controller.
Very light touches can be detected, as light as a 2 N (newtons Ð about 8 ounces of force). The controller can differentiate touches that are separated by more than 0.2 seconds.
We have constructed panels from 125 mm diagonally up to 1.2 meters diagonally.
Yes. NEMA-4 (IP 65) sealing of the force panel is quite easy. Clearly, sealing the rest of a display-touch system depends on system design.
InfiniTouch technology is based in a broad portfolio of patents and provisional patents.
Typically the load beams will be designed so that they deflect about 0.7 mm over the desired force sensing range.
Not at this time.
InfiniTouch works like a typical mouse. This mapping is the responsibility of the application developer or the operating system being used.
Yes; please contact QSI for current availability.
Currently some vibration in low frequency ranges (below 10 Hz) will make InfiniTouch report spurious "touches," rendering it unusable. We are working to compensate for vibration.
One of our patent applications includes a self-calibrating feature. We have units in the field and have not had any calibration issues.
We believe that the performance characteristics of InfiniTouch are comparable or superior to the best of the existing touch. Advantages include the integration of multiple materials in a single touch surface, elevated and irregular surfaces, surface attachments and penetrations in the touch surface.
There are no components that would wear out - the useful lifetime of an InfiniTouch panel is practically unlimited.
Mathematically, infinite means without bounds. InfiniTouch is not bounded by the restrictions that other touch technologies have.
We had a customer approach us in 1998 with a requirement that could not be met with any existing touch-screen technology. In working with this customer we "re-discovered" the concept of direct force measurement. Over the next six years we built numerous prototypes and developed knowledge of the capabilities of the technology. In 2004 we invented solutions to enhance the capabilities to the point that the product started to appear commercially viable, and we have accelerated development since that time.
