Mobile devices are used both at work and for leisure. Common features of mobile technology are mobility and small size. More serious tasks are performed with small screens and those tasks are important to perform efficiently and accurately. Screens are used for searching and gathering information and is also used to make decisions. Small screens are not only used for casual everyday tasks, but are also used for study, banking, health care and productive work.\nConflicting information can be found about how screen size affects human information processing and efficiency. Screen size has been shown to influence learning and task performance. Screen size seems to change the way human interact with user interface, so can screen size also influence decision making?\nThis study investigated how screen size affects the performance of an information retrieval and decision-making task using computational cognitive modeling.\nPrevious studies have shown that larger screens were generally more efficient completing tasks, but task difficulty, time pressure, and memory have also a role in task performance. An information retrieval and decision-making task was created for this study and the task was implemented to existing model. The model performed the task with different configurations to test how task difficulty, time pressure, and memory affected to performance. The simulations were analyzed with IBM SPSS Statistics to detect completion times and correct execution percentages between screen sizes.\nThe study shows that, the information retrieval and decision-making task was often performed more slowly with small screen. If there is a problem in visual movement and encoding (noise) it seems that large screen does not give advantage to completion time. Response accuracy decreased more with the small screen when the time pressure tightened. Weaker memory reduced task performance more with small screen.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-06-15T09:12:59Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-06-15T09:12:59Z (GMT).
