Hancock, Mark S., Shen, Chia, Forlines, Clifton and Ryall, Kathy (2005): Exploring non-speech auditory feedback at an interactive multi-user tabletop. In: Graphics Interface 2005 May 9-11, 2005, Victoria, British Columbia, Canada. pp. 41-50. Available online

“We present two experiments on the use of non-speech audio at an interactive multi-touch, multi-user tabletop display. We first investigate the use of two categories of reactive auditory feedback: affirmative sounds that confirm user actions and negative sounds that indicate errors. Our results show that affirmative auditory feedback may improve one's awareness of group activity at the expense of one's awareness of his or her own activity. Negative auditory feedback may also improve group awareness, but simultaneously increase the perception of errors for both the group and the individual. In our second experiment, we compare two methods of associating sounds to individuals in a co-located environment. Specifically, we compare localized sound, where each user has his or her own speaker, to coded sound, where users share one speaker, but the waveform of the sounds are varied so that a different sound is played for each user. Results of this experiment reinforce the presence of tension between group awareness and individual focus found in the first experiment. User feedback suggests that users are more easily able to identify who caused a sound when either localized or coded sound is used, but that they are also more able to focus on their individual work. Our experiments show that, in general, auditory feedback can be used in co-located collaborative applications to support either individual work or group awareness, but not both simultaneously, depending on how it is presented.”

“We present a new popup widget, called CoR{sup:2}Ds (Context-Rooted Rotatable Draggables), designed for multi-user direct-touch tabletop environments. CoR{sup:2}Ds are interactive callout popup objects that are visually connected (rooted) at the originating displayed object by a semi-transparent colored swath. CoR{sup:2}Ds can be used to bring out menus, display drilled-down or off-screen ancillary data such as metadata and attributes, as well as instantiate tools. CoR{sup:2}Ds can be freely moved, rotated, and re-oriented on a tabletop display surface by fingers, hands, pointing devices (mice) or marking devices (such as a stylus or light pen). CoR{sup:2}Ds address five issues for interaction techniques on interactive tabletop display surfaces: occlusion, reach, context on a cluttered display, readability, and concurrent/coordinated multi-user interaction. In this paper, we present the design, interaction and implementation of CoR{sup:2}Ds. We also discuss a set of current usage scenarios.”

“We investigate menu selection in circular and rectangular pop-up menus using stylus-driven direct input on horizontal and vertical display surfaces. An experiment measured performance in a target acquisition task in three different conditions: direct input on a horizontal display surface, direct input on a vertical display and indirect input to a vertical display. The third condition allows comparison of direct and indirect techniques commonly used for vertical displays. The results of the study show that both left-handed and right-handed users demonstrate a consistent, but mirrored pattern of selection times that is corroborated by qualitative measures of user preference. We describe a menu placement strategy for a tabletop display that detects the handedness of the user and displays rectangular pop-up menus. This placement is based on the results of our study.”

“ Software design is the act of determining the user's experience with a piece of software. It has nothing to do with how the code works inside, or how big or small the code is. The designer's task is to specify completely and unambiguously the user's whole experience. ”
