Issues and techniques in touch-sensitive tablet input

Abstract

Touch-sensitive tablets and their use in humancomputer interaction are discussed, It is shown that such devices have some important properties that differentiate them from other input devices (such as mice and joysticks). The analysis serves two purposes: (1) it sheds light on touch tablets, and (2) it demonstrates how other devices might be approached. Three specific distinctions between touch tablets and one button mice are drawn. These concern the signaling of events, multiple point sensing and the use of templates. These distinctions are reinforced, and possible uses of touch tablets are illustrated, in an example application. Potential enhancements to touch tablets and other input devices are discussed, as are some inherent problems. The paper concludes with recommendations for future work.

Evaluating the Paper-to-Screen Translation of Participant-Aided Sociograms with High-Risk Participants

“…While in-keeping with the technology available at the time, this is at odds with human-computer interaction (HCI) literature indicating that movement and interaction with certain elements is better accomplished with a finger [18, 11]. …”

Effect of elastic touchscreen and input devices with different softness on user task performance and subjective satisfaction

“…A variety of mechanical vibrations with piezoelectric actuators, voice coils, and other actuators have been developed in designing tactile feedback for mobile touch surfaces (Fukumoto and Toshiaki, 2001;Poupyrev et al, 2002;Poupyrev and Maruyama, 2003). However, despite the rising popularity of touch-based devices, the lack of dynamic tactile feedback when pressing soft buttons rendered graphically on a hard-surface touchscreen still poses a problem (Buxton et al, 1985;Lee and Zhai, 2009;Bau et al, 2010).…”

Haptic user interface enhancement system for touchscreen based interaction

“…However, the significant disadvantages still remain un-tackled thatlack, of viable haptic feedback ontouch screens limits or hinders interaction and user performance [1] [12]. Users' attention to visual and audio feedback is also weakened, during multimodal interaction, if there is no haptic feeling associated with physical human experience and controls such as buttons, switches, and knobs [5]. Moreover, users'perfonnance also deteriorates since users cannot rely on haptic cues [4].…”
