In this paper we describe design and implementation considerations for the graphic user interface for CoDesk (the Collaborative Desktop), which is an environment for CSCW (Computer Supported Cooperative Work). CoDesk is an attempt to make collaboration a natural part of the daily use of a computer. Our way to achieve this is to put the user in the centre of the computing in a similar way that a...

Managing the ever rapidly increasing image data is a very challenging task, which can be roughly divided into user side and computer side issues. Although fundamental problems on the computer side of the challenge, such as image content representation, similarity matching and intelligent retrieval have received extensive research effort, equally important and difficult issues on the user side, ...

(eds.), Distributed User Interfaces: Designing Interfaces for the Distributed Ecosystem, Human-Computer Interaction Series, DOI 10.1007/978-1-4471-2271-5_4, © Springer-Verlag London Limited 2012 Abstract In this paper, we describe a solution to obtain flexible user interface distribution across multiple devices, even supporting different modalities. For this purpose we extend...

In this paper we demonstrate usability analysis of Object-Z user-interface designs. Usability can be defined in terms of five salient properties of an interactive system: task efficiency, reuse, user-computer communication, robustness and flexibility. Formal user-interface designs have been touted as a basis for determining the usability of an interactive system prior to the expense of system d...

But what is this "environment"? For the majority of applications used by most mainstream computer users, such as spreadsheets, text editors, mail readers, graphical editors, CAD programs, etc., a direct-manipulation graphical interface constitutes the "environment" with which a software agent must interact in order to be ultimately useful to the user. The program might have internal representat...

For most computer systems, even virtual reality systems, sensing techniques are a means of getting input directly from the user. However, wearable sensors and computers offer a unique opportunity to redirect sensing technology toward recovering more general user context. Wearable computers have the potential to “see” as the user sees, “hear” as the user hears, and experience the life of the use...

A general user interface paradigm is presented which is capable of modelling iterative query refinement and embedding several common and advanced query techniques. A prototype implementation of this user interface called AQUA has been applied to the NCSTRL (Networked Computer Science Technical Reports Library) distributed digital

A value can be understood as a belief that one mode of conduct is preferable to others. The user-interface of computer games mediates all player conduct in the game and is therefore key to understanding how values are expressed both by and to the player. How the interface affects player’s expression and understanding of value in computer games is a relatively unknown quantity. We performed a qu...

Poor design criteria are responsible for wasting computer users time and are a hindrance to effective interaction with human centred systems. It is important that before any design of an interface is attempted an in-depth analysis of task and user needs must be undertaken. Questions need to be asked such as “What takes place during interaction between the user and the interface?” “Does the inte...
