Recognition of Psychologically Relevant Aspects of Context on the Basis of Features of Speech
Article
Full-text available
  • Aug 2009
Especially in mobile systems, one important part of the context of use involves psychological variables like cognitive load and time pressure. This paper looks at one possible way of capturing such aspects of context: the analysis of the features of the users' speech. In a replication and extension of an earlier study of our group, we created four...

Context 1
... The experimental environment simulated a situation in which a user is walking through a crowded airport terminal while asking questions to a mobile assis- tance system via speech (see Figure 1). In each of 80 trials, a picture appeared in the upper right-hand corner of the screen. ...
Context 2
... the basis of each picture, the subject was to ask a question, after motivating it with an introductory sentence. For example, for the picture shown in Figure 1, a subject might say "I'm getting thirsty. Is there . . . ...

The effects of age and cognitive load on peripheral-detection performance
Article
Full-text available
  • Jan 2019
Age-related declines in both peripheral vision and cognitive resources could contribute to the increased crash risk of older drivers. However, it is unclear whether increases in age and cognitive load result in equal detriments to detection rates across all peripheral target eccentricities (general interference effect) or whether these detriments b...
