Our Technology

Overview

SiMa Systems is a pioneer of Multi-Touch and Multi-Force (MT/MF) touch sensor technologies. SiMa’s resistive MT/MF touch technologies have unique functional characteristics enabling a new dimension of touch, gesture and pen input. Resolution of up to 20 points/mm affords uncompromised accuracy even for the most demanding applications. SiMa’s touch technologies can be integrated into a broad range of products from displays to touch pads.

SiMa’s touch technologies are packaged and delivered in a patented Terminal Interface Chip and Firmware licensing. OEMs, Systems Integrators and Developers use SiMa's technology to create "X-wire" (as opposed to 4-wire or 5-wire) resistive touch surfaces.

Features

Multi-Touch — The ability to recognize multiple and simultaneous touch points. Capable of recognizing ten or more simultaneous touch points at 1,000 updates per second.

Multi-Force — The ability to measure the “z axis”. This allows the user to locate a point without activating it, then, by exerting slightly more pressure to actually activate the point. There is no need to lift fingers and retouch.

Dynamic Home Row — Allows the user to touch the sensor without looking at the display or pad, and intuitively the sensor understands the purpose of the gesture (i.e. typing, commands). The sensor can be programmed for virtually any manner of touch and gesture input.

High Resolution — The resolution (points/mm) remains constant regardless of sensor size.

Auto Calibration — The touch sensor self calibrates with each touch providing optimal point data at all times.

Standard Materials and Processes — Same materials and manufacturing processes as those used for standard resistive sensors. This provides a proven and stable means to implement SiMa’s touch sensor wherever standard resistive sensors are now deployed.
