Tangible User Interfaces (TUIs) are those in which users interact with a digital system through the direct manipulation of physical objects (tokens). Tokens are directly linked to a certain data/functionality within the system, so manipulation of these objects affects the system behavior. This paper introduces TanQuery, a tangible system to support the process of learning Relational Algebra. TanQuery incorporates components to detect and track tokens, and to analyze and execute query trees. The system was tested by university students, and obtained results allowed to observe and analyze that students found this type of interface useful and pleasant. Keywords: Tangible user interfaces; relational algebra.

Design And Testing

This is an opinion piece about the relationship between the fields of human-computer interaction (HCI), and artificial intelligence (AI). The ultimate goal of both fields is to make user interfaces more effective and easier to use for people. But historically, they have disagreed about whether "intelligence" or "direct manipulation" is the better route to achieving this. There is an unjustified perception in HCI that AI is unreliable. There is an unjustified perception in AI that interfaces are merely cosmetic. This disagreement is counterproductive.This article argues that AI's goals of intelligent interfaces would benefit enormously by the user-centered design and testing principles of HCI. It argues that HCI's stated goals of meeting the needs of users and interacting in natural ways, would be best served by application of AI. Peace.

Standard Set

Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation may be used to convey a feeling of substance to the objects being manipulated by the user. To lay a solid framework for this work, an extensive review of current applications of animation to user interfaces is presented. This chapter goes on to present an expansion of the 2D animation concepts to the domain of 3D interfaces for multimedia and virtual reality. This chapter focuses on the improvement of the legibility of users’ actions in 3D multimedia and virtual reality applications, and details animation effects to support this legibility. In particular, I present animation effects for 3D graphical object manipulation. These effects include a standard set of 3D direct manipulation operations which have been extended to include animated visual feedback to add substance, operation cues for the user and constraint visualisation. The visual feedback effects using 3D warping can substitute for haptic feedback, as in the case of the squashing of an object when pressed against a wall, or the stretching of an object to show frictional forces. Finally, a pinning effect is explored for multiple users’ manipulating a common object in a collaborative environment.

Searching Performance

This study investigates the effects of interaction devices on performance of using WWW user interface for older users, and ways to design appropriate user interfaces to enhance browsing and searching performance for older users. Two experiments were designed and conducted to test two hypotheses, that for older novice users, browsing and searching performance and attitudes will be better with a direct manipulation devices rather than with indirect manipulation device. The results indicated that older users using touch screen were faster and less frustrated than older users using voice control and mouse. Moverover, older users using touch screen were faster and less frustrated than older users using voice control and mouse, and older users using mouse and keyboard were less frustrated than older users using voice control
