Heuristic evaluation is an informal method of usability analysis where a number of evaluators are presented with an interface design and asked to comment on it. Four ex-periments showed that individual evaluators were mostly quite bad at doing such heuristic evaluations and that they only found

We introduce the concept of Graspable User Interfaces which allow direct control of electronic or virtual objects through physical handles for control. These physical artifacts are essentially new input devices which can be tightly coupled or “attached ” to virtual objects for manipulation

Recent debate has centered on the relative promise of focusing user-interface research on developing new metaphors and tools that enhance users' abilities to directly manipulate objects versus directing effort toward developing interface agents that provide automation. In this paper, we

paradigm of human-computer interaction. In this chapter, we discuss a growing space of interfaces in which physical objects play a central role as both physical representations and controls for digital information. We present an interaction model and key characteristics for such "tangible user

trategies with claims of "user friendliness" are yielding to a more scientific - 2 - approach. Measurement of learning time, performance, errors, and subjective satisfaction is now a part of the design process. Design of a User Interface Design of a user interface begins with task

Almost as long as there have been user interfaces, there have been special software systems and tools to help design and implement the user interface software. Many of these tools have demonstrated significant productivity gains for programmers, and have become important commercial products. Others

This paper addresses the problem of the graceful degradation of user interfaces where an initial interface is transferred to a smaller platform. It presents a technique for pagination of interaction spaces (e.g., windows, dialog boxes, web pages) based on a multi-layer specification in the user

This paper addresses two questions related to educational multimedia applications: . What lessons should we learn from today's Graphical User Interfaces (GUIs)?, and . What the user interfaces should look like in the future? We address the first question by drawing on our experience from

Our knowledge concerning software engineering tasks has grown considerably during the last 20 years and code entanglement has been tackled by several techniques such as aspect-oriented software engineering and component based software engineering.
