In this paper we report on an eye-tracking experiment conducted with 60 participants to gain an understanding of how people interact with blog environments. We compared a standard blog interface with a novel contextual blog interface, which dynamically adjusts its contextual navigation to a selected article. We measured task performance and interaction behaviour for explorative tasks and goal-o...

Sedentary people have a hard time incorporating physical activity into their lives. Most physical activity monitoring systems focus on performance numbers. However, people need information beyond performance numbers to help them understand how their lifestyle affects how physically active they are. The main question of our research is how people can use contextual information from ubiquitous co...

Subjectivity word sense disambiguation (SWSD) is automatically determining which word instances in a corpus are being used with subjective senses, and which are being used with objective senses. SWSD has been shown to improve the performance of contextual opinion analysis, but only on a small scale and using manually developed integration rules. In this paper, we scale up the integration of SWS...

BACKGROUND Community health workers (CHWs) are increasingly recognized as an integral component of the health workforce needed to achieve public health goals in low- and middle-income countries (LMICs). Many factors intersect to influence CHW performance. A systematic review with a narrative analysis was conducted to identify contextual factors influencing performance of CHWs. METHODS We sear...

Behavioral and neural studies of selective attention have consistently demonstrated that explicit attentional cues to particular perceptual features profoundly alter perception and performance. The statistics of the sensory environment can also provide cues about what perceptual features to expect, but the extent to which these more implicit contextual cues impact perception and performance, as...

Icons, or pictorial and graphical objects, are commonly used in human-computer interaction (HCI) fields as the mediator in order to communicate information to users. However, there have been little studies focusing on the majority of the world’s population – semi-literate communities – in terms of icon design. In this study, a new icon taxonomy of four quadrants, namely abstract-general, abstra...

Mobile computing is an empowering notion to many people. Different design and evaluation paradigms need to exist for mobile computing devices and environments. The context of use must be considered because there are multiple tasks taking place in many mobile computing interactions. However, few empirical studies on mobile computing regarding changes in context impact users’ abilities to perform...
