<b>Motivation</b> -- To improve the current practice of scenario-based usability evaluation by suggesting a new method for generating more comprehensive scenarios and using the scenarios more easily and systematically. <b>Research approach</b> -- Work domain analysis (WDA) concept in cognitive work analysis (CWA) framework was employed to develop a method(More)
In this report, we describe the work done in a project that explored the human information processing aspects of a personal memex (a memex to organize personal information). In the project, we considered the use of the personal memex, focusing on information recall, by three populations: people with Mild Cognitive Impairment, those diagnosed with Macular(More)
It is well established that motor action/imagery provokes an event-related desynchronization (ERD) response at specific brain areas with specific frequency ranges, typically the sensory motor rhythm and beta bands. However, there are individual differences in both brain areas and frequency ranges which can be used to identify ERD. This often results in low(More)

In this paper, we discuss re-finding personal information from a human information processing perspective. We describe the design of a prototype that explored the human information processing aspects of a personal memex (a memex to organize personal information). In the project, we considered the use of the personal memex, focusing on information recall, by(More)
PURPOSE In brain-computer interfaces (BCIs), electrical brain signals during motor imagery are utilized as commands connecting the brain to a computer. To use BCI in patients with stroke, unique brain signal changes should be characterized during motor imagery process. This study aimed to examine the trial-dependent motor-imagery-related activities in(More)
