QSI Corporation is a human machine interface and mobile data terminal manufacturer located in Salt Lake City, Utahthat specializes in rugged, environmentally tested terminals.

History
Established in 1983 by James K. and John D. Elwell, QSI began manufacturing low-power C-44 bus board computers. In 1984, QSI introduced their first terminal (the “QTERM®”), a simple 20-key unit with a 4x16 display.

Technology
QSI’s human machine interface and mobile data terminals are CE certified, RoHS compliant and NEMA 4/12/13 rated. Vissumo (formerly InfiniTouch) was first developed at QSI. Vissumo touch screens use the applied force of a touch to determine location and pressure on a screen (concept originally pioneered by IBM in 1960).
