The use of 3D printed objects could provide an easy-to-use, well-received, person-centered approach that augments current reminiscence strategies for PWMLs.
Cultural models in terms of the characteristics and content of folk theories and folk psychology have been important to social scientists for centuries. We suggest that they should be at the heart of the scientific study of human-computer interaction (HCI). The CULTUSAB project is conducting an in-depth investigation of the key dimensions of culture that affect usability testing situations, including language, power distance, and cognitive style. All phases of the usability test are being evaluated for cultural impact, including planning, conducting, and reporting results. Special attention is being focused on subject-evaluator communication and cultural bias in the test design and structure of the user interface being tested. Experiments are being replicated in three countries: Denmark, India and China. The research will result in new testing methods and guidelines that increase the validity of usability tests by avoiding cultural bias, and allow us to produce comparable results across different countries.
For the convenience of firefighters' decision-making and operation, touch screen display was chosen as the preferred interface for a fire information display system. Few studies were conducted to determine comfortable button/icon size on touch screens. This experiment investigated the effect of four factors on operators' performance with touch screen: 1) button size (20*20, 30*30, 40*40, and 50*50 pixels 2), spacing between buttons (0, 5, 10, and 20 pixels), 3) button/icon types (digit buttons only, picture icons only, combination), and 4) glove wearing (wearing vs. not wearing). 14 males were asked to accomplish a series of matching tasks on touch screen with the forefinger of right hand. Results showed that the spacing between buttons/icons, and wearing or not wearing a glove did not affect performance. Subjects pointed to the digit buttons faster than the other two kinds of buttons/icons. There was a significant difference among button/icon sizes. People performed best when it was equal to or bigger than 40*40 pixels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
