Abstract [en]

This thesis deals with the term 'context' and the aim has been to reason about the term in order to see whether it is possible to reach a satisfactory understanding of the concept. But the thesis is also a journey into human reasoning and conveys a certain view of human cognition. It aims to synthesise results of studies within psychology, cognitive science, anthropology, and human-computer interaction. My understanding is that context is not something we are a part of, but rather something we create mentally in relation a specific goal. Determination of something ambiguous thus comes from top-down processes related to a goal. I believe context has been wrongly interpreted in HCI as that which a user is situated in and which a product is being used in. I suggest instead a separation between the user environment and the user context.

Abstract [en]

Educational software in the form of games or so called "computer assisted intervention" for young children has become increasingly common receiving a growing interest and support. Currently there are, for instance, more than 1,000 iPad apps tagged for preschool. Thus, it has become increasingly important to empirically investigate whether these kinds of software actually provide educational benefits for such young children. The study presented in the present article investigated whether preschoolers have the cognitive capabilities necessary to benefit from a teachable-agent-based game of which pedagogical benefits have been shown for older children. The role of executive functions in children's attention was explored by letting 36 preschoolers (3;9-6;3 years) play a teachable-agent-based educational game and measure their capabilities to maintain focus on pedagogically relevant screen events in the presence of competing visual stimuli. Even though the participants did not succeed very well in an inhibition pretest, results showed that they nonetheless managed to inhibit distractions during game-play. It is suggested that the game context acts as a motivator that scaffolds more mature cognitive capabilities in young children than they exhibit during a noncontextual standardized test. The results further indicate gender differences in the development of these capabilities.

Abstract [en]

Introducing automation in a human-machine system changes the tasks performed by human operators. It is difficult to analyse systems for which there are no experienced operators. This issue emerged within a project with the aim to develop a human–machine interface for a highly automated long-haul vehicle. To handle the problem, a formative strategies analysis method with promises to enable desktop analyses through predefined strategy categories was adopted. The method was used to investigate strategies for controlling the future long haul vehicle by conducting workshops with today's drivers. The method was shown to be a valuable asset in eliciting strategies for revolutionary design.
