Critical Overview

Many studies in the field of human-computer interaction (HCI) point to gesture-based interaction (GBI) as a transformative method for communicating with computers. GBI allows people to use common body language like waving or pointing to manipulate devices without physically touching them. Current research suggests that moving beyond traditional mechanical devices such as a mouse or keyboard may create richer and more ‘natural’ user experiences. Despite this finding, this mode of interaction has not seen broadscale adoption. A critical analysis of the work taking place in both industry and HCI studies demonstrates tension between the theory and practice of creating gesture-centric interfaces. This study provides a critical overview of the issues, technological, design and social, that pose a challenge to the widescale adoption of this technology.

A Performance

Flash-based solid state disks (SSD) is a performance based data storage technology that optimizes the use of flash-based technology to implement its data storage capabilities compared with mechanically available data storage technologies. It has been argued in theory and practice that SSD devices are better performers compared with mechanical devices. To improve the efficiency of a flash memory SSD device, it is important for it to be designed to be computationally support parallel operations.

Interaction methods based on computer-vision hold the potential to become the next powerful technology to support breakthroughs in the field of human-computer interaction. Non-invasive vision-based techniques permit unconventional interaction methods to be considered, including use of movements of the face and head for intentional gestural control of computer systems. Facial gesture interfaces open new possibilities for assistive input technologies. This chapter gives an overview of research aimed at developing vision-based head and face-tracking interfaces. This work has important implications for future assistive input devices. To illustrate this concretely the authors describe work from their own research in which they developed two vision-based facial feature tracking algorithms for human computer interaction and assistive input. Evaluation forms a critical component of this research and the authors provide examples of new quantitative evaluation tasks as well as the use of model real-world applications for the qualitative evaluation of new interaction styles.

The Right

This chapter provides a critical analysis of the legal framework for access to information particularly information held by government in Tanzania. The analysis intends to establish whether the existing Right To Information (RTI) legal framework and ICT development in Tanzania facilitates universal and requisite access to government information. In order to do that, the chapter utilises a literature review to understand contemporary trends in both theory and practice. In addition, journal articles, books, reports, case law, and pieces of legislation focusing on RTI are visited to obtain deeper insights in the topic under scrutiny. The findings indicate that, despite Tanzania's efforts to embrace democracy virtues, good governance, and technology, the country lacks adequate legal framework to facilitate universal access to government information and ensure that the Right To Information (RTI) is observed in all the socio-economic contexts. To rectify this problem, there is need to enact the RTI law with clear focus of encouraging access to government information. Although two bills (the Media Service Bill [MSB] and the 2011 RTI) are currently being debated, it is not clear yet when they will become law and subsequently practiced.

Computer Interaction

User experience determines the quality of an interaction being used by an actor in order to achieve a specific outcome. The actor can have varying roles and evolving needs, thus reviewing and predicting experiences are important. As an actor uses and gains feedback, the feedback guides individual and group behavior, thus becoming pertinent to how interactions occur. This chapter questions how artefacts are designed to promote such interactions and what processes should be incorporated to ensure successful interpretation, use, (physical) reaction, and conation. This chapter discusses the effects of user experiences today based on societal needs and expectations. It shows how the field is delineated into numerous sub-topics, all of which can stand on their own yet still draw from each other. The discussions will include fields such as cognitive science, human-computer interaction, learning sciences, and even ergonomics to show how design and subsequently interactions can assist in having successful user experiences.

Rule Making

This chapter exposes how the realization of digital transformation (DT) derives from the decisional communication of rule-making “chosen” alternatives, which originate in the self-referenced informational space, according to the dual perspective of reality adopted in evolutionary economics. Based on a critical analysis of scholarly literature to identify key proposals that support the definition of DT strategies, this research establishes the relevance of the fundamental tenets of autopoiesis theory, such as operational closure, structural coupling, and languaging, in the context of digitalization, to harmonize such DT strategy proposals to the structure of the organization in terms of decision premises. The internal availability of these decision premises determines the type of digitalization potential that can be self-observed by the organization, reinterpreting the attributes of DT in a framework that recognizes the sets of DT alternatives as decision premise dichotomies, with implications for theory and practice.
