This paper presents the “extremity” approach to creating user-interface experiences. We describe a class of dataacquisition systems called “extremity-computing devices” and their broad implications to user-interface design scenarios. These devices are used to interface sensors and effectors in wearable-computer applications. Instead of wearing a complete computer, outfitted with interface, stor...

Communication technology, such as devices using the Bluetooth technology, has developed with a tremendous speed and is bringing us to the age of ubiquitous computing. In contrast, the graphical user interface (GUI) used on standard desktop computers has not changed much in the last 15 years. An analysis of Bluetooth usage models aids the discovery of the implicit assumptions behind the Windows ...

User Interface Patterns are not sufficiently explored at the Conceptual phase. Work in area of User Interface patterns is predominantly done at design phase but not enough work is dedicated to analysis patterns. This paper shows different examples of abstract user interface patterns and explores the impact of such patterns in the software lifecycle. Conceptual User Interface Patterns can be use...

The objective behind Tangible User Interfaces (TUIs) is to allow users to interact with computers through familiar tangible objects, thereby taking advantage of the richness of the tactile world combined with the power of computer-based simulations. TUIs “give physical form to digital information, employing physical artifacts both as representations and controls for computational media” [1]. Th...

Introduction Modern designers of graphical user interfaces, or GUIs, have obtained design patent protection for creative computer software displays, a realm previously limited to copyright. The difference in protection is important. Design patents do not require copying, while copyright does. Design patents do not have a fair use defense, while copyright does. Design patents do not exclude prot...

Advances in usability and design techniques (e.g. user-centered design) try to facilitate the use of interactive systems. However, users still have to adapt to interactive systems, i.e. they have to learn the steps required to accomplish a task either by trial and error or by obtaining help. While advanced users are usually able to adapt without much effort this is far from being the case with ...

Interface designers have been studying how to construct graphical user interfaces (GUIs) for a number of years, however adults are often the main focus of these studies. Children constitute a unique user group, making it necessary to design software specifically for them. For this study, several interface design frameworks were combined to synthesize a framework for designing educational softwa...

promises to bring huge volumes of information to us faster than ever before. Even now, reports, data, music, and movies flood our electronic and paper worlds. Once only executives and researchers were required to handle large amounts of information. Today, home users are swamped with information from their broadband connections. It seems most of us live in a kind of semi-organized information s...

Icons, widely used in computer programs, are part of the Graphical User Interface (GUI). They facilitate computer use regardless of users’ level of expertise. The authors report the results of a study focused on measuring performance of computer users in correctly and quickly associating toolbar icons and the action they represent in GUI. The study aimed to investigate the relationships between...

This demonstration shows a city-planning system based on augmented reality with tangible interface. Miniature models, illustrations and graphical computer displays have been used for the comparison and consideration in city-planning process. Augmented reality technology enables users to consider of city plans more effectively and easily. One important issue of the augmented reality environment ...
