This paper explores three interfaces for constructing queries on alphabetic field values with a touchscreen interface; including a QWERTY keyboard, an Alphabetic keyboard, and a Reduced Input Data Entry (RIDE) interface. The RIDE interface allows field values to be entered with fewer “keystrokes” (touches) than either keyboard while eliminating certain errors. In one test database, the RIDE interface required 69% fewer keystrokes than either keyboard interface. %B Proceedings of the 1990 ACM annual conference on Cooperation %S CSC '90 %I ACM %C New York, NY, USA %P 1 - 7 %8 1990/// %@ 0-89791-348-5 %G eng %U http://doi.acm.org/10.1145/100348.100349 %R 10.1145/100348.100349
