In this article we will examine some important issues related to human-computer interaction (HCI). This will be followed by a discussion of usability and its underlying principles and properties. The dependability of computer systems is intrinsically multi-faceted. Dependable hardware is patently of limited value unless accompanied by dependable software. Neither helps greatly if human interaction with the hardware and software system is fault-prone and the dependable socio-technical performance of an inappropriate task may cause wider damage (MacKenzie, 2000).

The study of computing technology and user interfaces was initiated during the 1970s when industrial research laboratories began to focus on human-computer interaction (HCI) (Badre, 2002). In the 1980s, the personal computer was introduced, thus expanding the need for designing effective user interfaces. HCI became a discipline during this time, and the Association for Computing Machinery (ACM) established the Special Interest Group in Computer Human Interaction. One of the first textbooks on HCI, Designing the User Interface: Strategies for Effective Human-Computer Interaction (Schneiderman, 19891), was published. Shortly thereafter, HCI became part of the ACM curriculum promoting the development of effective user interfaces. Software tools were developed in order to assist in designing usable interfaces while employing usability engineering methods. Many of these methods focused on usability from the perspective of ease of use, ease of learning, user satisfaction, and zero defects (Nielsen, 1993).

This paper is written by two people who come from rather different backgrounds, yet who, at the same time, share similar concerns about the human-computer interaction (HCI) area. One of us has a background in computing and cognitive science. The other person has a background in software engineering and computer systems design. As both of us are concerned with making more useful and usable computer applications we decided to look further for frameworks to help us. In this paper we shall try to expose some of the problems that we encountered in our joint effort to understand the HCI area and contribute to it, and to discuss some of the tensions and alternative viewpoints that we met on the way. The paper does not contain a solution to the problems of HCI. Rather, it contains a dialogue with ourselves about the matters of our concern, and we invite the reader to join this dialogue: our focus is on technology in use, where we emphasize the setting in which a piece of technology is used.

Collaborative business and information systems design touches a number of issues that lie within the realm of different research areas. It deals with design as such, and in particular with design in and for groups. It is also concerned with socio-technical systems and hence with human-computer interaction as well as IT-mediated human-human interaction. This introduces collaboration issues. The significant complexity of the business and information systems that are in the focus of the design endeavor calls for modeling as an instrument for managing this complexity. This article maps the terrain of collaborative business and information systems design by surveying the contributions that are made by related areas of research.

Gestures are a natural input method for human communication and may be effective for drivers to interact with in-vehicle infotainment systems (IVIS). Most of the existing work on gesture-based human-computer interaction (HCI) in and outside of the vehicle focus on the distinguishability of computer systems. The purpose of this study was to identify gesture sets that are used for IVIS tasks and to compare task times across the different functions for gesturing and touchscreens. Task times for user-defined gestures were quicker than for a novel touchscreen. There were several functions that resulted in relatively intuitive gesture mappings (e.g., zooming in and zooming out on a map) and others that did not have strong mappings across participants (e.g., decreasing volume and playing the next song). The findings of this study suggest that user-centric gestures can be utilized to interact with IVIS systems instead of touchscreens, and future work should evaluate how to account for variability in intuitive gestures. Understanding the gesture variability among the end users can support the development of an in-vehicle gestural input system that is intuitive for all users.

The objectives of the debate are (1) to foster a frank discussion and exchange of ideas on the potential value for the design of user interfaces of HCI-related scientific research - both basic research in perception, cognition, and social psychology and applied research on how people interact with computer systems, (2) to identify ways in which technology transfer (from researchers to designers) and design-need transfer (from designers to researchers) can be enhanced, and (3) to continue our on-going attempt to increase the dialogue between HCI researchers and practitioners (see Bias, 1994; Bias, Gillan, and Tullis, 1993; Gillan and Bias, 1992).

Traditional human–computer interaction devices such as the keyboard and mouse become ineffective for an effective interaction with the virtual environment applications because the 3D applications need a new interaction device. An efficient human interaction with the modern virtual environments requires more natural devices. Among them the "Hand Gesture" human–computer interaction modality has recently become of major interest. The main objective of gesture recognition research is to build a system which can recognize human gestures and utilize them to control an application. One of the drawbacks of present gesture recognition systems is being application-dependent which makes it difficult to transfer one gesture control interface into multiple applications. This paper focuses on designing a hand gesture recognition system which is vocabulary independent as well as adaptable to multiple applications. This makes the proposed system vocabulary independent and application independent. The designed system is comprised of the different processing steps like detection, segmentation, tracking, recognition, etc. Vocabulary independence has been incorporated in the proposed system with the help of a robust gesture mapping module that allows the user for cognitive mapping of different gestures to the same command and vice versa. For performance analysis of the proposed system accuracy, recognition rate and command response time have been compared. These parameters have been considered because they analyze the vital impact on the performance of the proposed vocabulary and application-independent hand gesture recognition system.
