Testing for Transition

Ashley Lierman, Bethany Scott, Mea Warren, Cherie Turner
2019 Information Technology and Libraries  
Significant findings include that users need clear directions and titles that incorporate familiar terminology, do not readily understand the purpose of guides, and are easily overwhelmed by excess information  ...  This information was collected using an open-card-sort study, two face-to-face, think-aloud testing protocols, and an online survey.  ...  Consistently, testers tended to gravitate toward course guides even when subject guides would have been more appropriate for a given task, and some users expressed that this choice was because of the greater  ...

Task Knowledge Based Retrieval for Service Relevant to Mobile User's Activity [chapter]

Takefumi Naganuma, Shoji Kurakake
2005 Lecture Notes in Computer Science  
Key components are a task knowledge base of tasks that a mobile user performs in daily life and a service knowledge base of services that can be used to accomplish user tasks.  ...  We also show preliminary user test results; they indicate that the system allows a user to find appropriate services quicker with fewer loads than conventional commercial methods.  ...  For instance, when the user's context is "midnight", the task of "travel by train" should not be associated with the user if there are no train services in midnight. 6.  ...
