Horizontal Selection: An Evaluation of a Digital Tabletop Input Device
نویسندگان
چکیده
Recent advances in digital tabletop touch-and-gesture-activated screens have allowed for small group collaboration. The newest generation screens simultaneously support multiple users, multiple contact points per user, and gesture recognition. Although the usefulness and potential of these devices has been demonstrated, a formal quantitative evaluation of their performance has not been performed to date. This paper investigates the performance characteristics of a front-projected, 1:1 perspective, touch interface in consideration of Fitts’ law. Specifically, this study evaluates the Mitsubishi Electric Research Laboratories’ (MERL) DiamondTouch digital tabletop. This paper explores the hypothesis that selection is faster and more accurate on horizontal digital tabletops compared to a mouse.

متن کاملImproving Menu Placement Strategies for Pen Input
Pen-based interaction is becoming a commonplace two degree-of-freedom alternative to the mouse. The use of pen input allows users to acquire targets directly on a computer display. This style of interaction introduces a unique form factor and a new set of considerations in the design of applications for such devices. This thesis presents a series of experiments designed to evaluate the use of p...
متن کاملAPDT: An Agile Planning Tool for Digital Tabletops
This paper presents Agile Planner for Digital Tabletops (APDT) as a tool that facilitates agile planning meetings using large horizontal displays. Utilizing APDT on a reasonably sized digital tabletop allows collaborators to create, edit, move, rotate, toss and delete index cards just like they would do with paper artifacts. APDT provides a multimodal input system that supports gesture-, handwr...

متن کاملTMAR: Extension of a Tabletop Interface Using Mobile Augmented Reality
Recently, many researchers have worked on tabletop systems. One issue with tabletop interfaces is how to control the table without using conventional desktop input devices such as a keyboard or mouse. A second issue is allowing multiple users to simultaneously share the tabletop system. In this paper we explore how Augmented/mixed reality (AR/MR) technology can be used to explore these issues. ...
