There is a substantial body of research on mHealth interventions in low-resource settings, but little empirical understanding of use by staff in established health facilities. What evidence there is indicates divergent outcomes. In order to generate insight into this phenomenon we undertake an exploratory study of mHealth use in several public clinics, where the staff are required to perform a ...

This paper presents the findings from a case study to investigate how undergraduate students used the output from a teamwork support tool. In designing this sort of software tool usability is considered, but analysis of the findings from this research suggests that the affordance of any support tools should also be considered, because without adequate signposting, the perceived affordance may n...

With more than one third of the world’s population being online, the Internet has increasingly become part of modern living, giving rise to popular literature that often takes a teleological and celebratory perspective, heralding the Internet and Web 2.0 specifically, as an enabler of participation, democracy, and interactivity. However, one should not take these technological affordances of We...

There is much positive research on computer-supported collaborative learning (CSCL) environments in asynchronous distributed learning groups (DLGs). There is also research that shows that contemporary CSCL environments do not completely fulfil expectations on supporting interactive group learning, shared understanding, social construction of knowledge, and acquisition of competencies. There app...

The idea that to perceive an object is to perceive its affordances—that is, the interactions of the perceiver with the world that the object supports or affords—is attractive from the point of view of theories in cognitive science that emphasize the fundamental role of actions in representing an agent’s knowledge about the world. However, in this general form, the notion has so far lacked a for...

Perceived affordance is utilized as a theoretical lens to explore factors influencing consumers’ positive or negative perceptions of Web advertisements, which is one type of information artifacts. Content and form are two main attributes shared by information artifacts. Based on the literature review and content analysis, a conceptual framework is proposed to shed light on perceived affordance ...

Physical interfaces have been proposed as a way to realize natural interactions with ubiquitous computing environments. The successful design of such interfaces requires design approaches that integrate aspects of our world which are usually treated separately in traditional system development approaches. This paper describes a design approach based on Gibson concept of affordance. We demonstra...

This paper develops and evaluates a new tensor field representation to express the geometric affordance of one object over another. We expand the well known bisector surface representation to one that is weight-driven and that retains the provenance of surface points with directional vectors. We also incorporate the notion of affordance keypoints which allow for faster decisions at a point of q...
