We describe six different touchscreen based toggle switches allowing the control of two state devices by novice or occasional users. The user interfaces, ranging from button type toggles to sliding toggles are demon-strated on an IBM PC. Results from a formative usability test are given indicating that all the toggles described here can be used with very low error rates. The sliding toggles were rated harder to use and were least preferred. On the other hand they offer other advantages such as the reduction of the risk of undesired activation. |
