Three Computer Keyboards Operated by Hissing

Hissing might be a means of operating equipment, suggests this study:

“Predictive Scanning Keyboard Operated by Hissing,” Ondřej Poláček [pictured here], Zdeněk Mikovec, and Pavel Slavik, in Proceedings of the 2nd IASTED International Conference Assistive Technologies, 2012, pp. 862-9. The authors, at Czech Technical University in Prague, report:

“This strategy is demonstrated on three virtual keyboards operated by hissing – a novel interaction method suitable for severely motor impaired people with speech impairments. An experiment with 39 users was conducted to compare the keyboards to three existing scanning keyboards. The participants were able to enter a text by hissing at the speed of 10-16 characters per minute.”
