Movement time and velocity of movement have shown very similar relationships, possibly because of the lack of extreme testing conditions. Most previous research evaluated conditions with only constant path length (A) of movement.<\/jats:p>\n                  <jats:p>Method: A total of 15 participants performed a mouse steering task within a constrained path at various angles. The independent variables were track width (W), path length, and path angle. Movement time was the dependent variable.<\/jats:p>\n                  <jats:p>Results: Analyses showed a significant effect of movement direction on movement time, and the relationship was approximately sinusoidal and symmetrical about the horizontal axis. Path length had a significant effect on speed of movement, which was not that apparent on movement time. At low A\/W values, movements appeared to be ballistic.<\/jats:p>\n                  <jats:p>Conclusion: Tracking within constrained paths can be modeled to account for the effect of path angle.<\/jats:p>\n                  <jats:p>Application: Vertical hand movements, especially within constrained paths, may not be ideal from a performance and biomechanical standpoint. The performance curve gradients are a good way to evaluate and standardize the testing of input devices and to define acceptable speeds for various tolerances in computer and industrial tasks that involve angular motions. The results of this experiment will help designers to optimize products and training programs.<\/jats:p>","DOI":"10.1177\/0018720811424743","type":"journal-article","created":{"date-parts":[[2011,12,1]],"date-time":"2011-12-01T11:38:16Z","timestamp":1322739496000},"page":"138-150","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Constrained Path Tracking at Varying Angles in a Mouse Tracking Task"],"prefix":"10.1177","volume":"54","author":[{"given":"Namal","family":"Thibbotuwawa","sequence":"first","affiliation":[{"name":"Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ravindra S.","family":"Goonetilleke","sequence":"additional","affiliation":[{"name":"Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Errol R.","family":"Hoffmann","sequence":"additional","affiliation":[{"name":"Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,11,29]]},"reference":[{"key":"bibr1-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1037\/0096-1523.16.2.248"},{"key":"bibr2-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1145\/258549.258760"},{"key":"bibr3-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1145\/302979.303133"},{"key":"bibr4-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1145\/365024.365027"},{"key":"bibr5-0018720811424743","doi-asserted-by":"publisher","DOI":"10.2307\/1418242"},{"key":"bibr6-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1177\/1545968306298414"},{"key":"bibr7-0018720811424743","doi-asserted-by":"publisher","DOI":"10.2307\/1418708"},{"key":"bibr8-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1080\/14640748308402133"},{"key":"bibr9-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1007\/BF00205114"},{"key":"bibr10-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1016\/0167-9457(95)00009-H"},{"key":"bibr11-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1145\/302979.303042"},{"key":"bibr12-0018720811424743","doi-asserted-by":"publisher","DOI":"10.1080\/00140137108931246"},{"key":"bibr13-0018720811424743","first-page":"184","volume-title":"Proceedings of the 26th Spring Annual Conference and World Productivity Congress","author":"Drury C.
