Indirect input techniques allow users to quickly access all parts of tabletop workspaces without the need for physical access; however, indirect techniques restrict the available social cues that are seen on direct touch tables. This reduced awareness results in impoverished coordination; for example, the number of conflicts might increase since users are more likely to interact with objects that another person is planning to use. Conflicts may also arise because indirect techniques reduce territorial behavior, expanding the interaction space of each collaborator. In this paper, we introduce three new tabletop coordination techniques designed to reduce conflicts arising from indirect input, while still allowing users the flexibility of distant object control. Two techniques were designed to promote territoriality and to allow users to protect objects when they work near their personal areas, and the third technique lets users set their protection levels dynamically. We present the results of an evaluation, which shows that people prefer techniques that automatically provide protection for personal territories, and that these techniques also increase territorial behavior.

“…Open-loop control techniques, such as Drag-and-Throw [3] or Shuffle [6], let the user define the direction in which the object should move at the beginning of the action. Once the automatic part of the movement was initiated, they do not provide the user with opportunities for interaction, so they cannot be corrected anymore.…”

Flicking is a common interaction technique to move objects across large interactive surfaces, but little is known about its suitability for use on non-planar, curved surfaces. Flicking consists of two stages: First, visually determining the direction in which to flick the object, then planning and executing the corresponding gesture. Errors in both stages could influence flicking accuracy. We investigated flicking interactions on curved interactive surface to evaluate which type of error influences accuracy. Therefore, we carried out three user studies to analyze how each stage of flicking on a curved surface is influenced. Our main findings are: 1) Flicking gestures are more accurate if horizontal and vertical surface are joined by a continuous curve than if they are separated by an edge or gap. 2) Flicking gestures on curved surfaces are mostly influenced by the motor execution stage of the gesture rather than the visual perception stage. 3) Flicking accuracy decreases as the starting point of the gesture is moved closer to the curve. 4) We conclude with a first mathematical model to estimate the error users will make when flicking across a curve.

“…Many of these approaches have also been designed to mitigate the orientation problem. In order to help collaborators pass information across large screen displays, Geißler [1] introduced a "throwing" gesture that enables interface items to smoothly slide across larger distances. However, this throwing gesture tends to be too inaccurate for some tabletop activities, such as moving an item to a specific location across on the display [9].…”

Tabletop displays provide exciting opportunities to support individual and collaborative activities such as planning, organizing, and storyboarding. It has been previously suggested that continuous flow of interface items can ease information access and exploration on a tabletop workspace, yet this concept has not been adequately studied. This paper presents an exploratory user study of Interface Currents, a reconfigurable and mobile tabletop interface component that offers a controllable flow for interface items placed on its surface. Our study shows that Interface Currents supported information access and sharing on a tabletop workspace. The study findings also demonstrate that mobility, flexibility, and general adjustability of Interface Currents are important factors in providing interface support for variations in task and group interactions.
