A multidirectional pointing task was used to assess the motor performance and the users\u2019 ability to learn such a task. The evaluation was based on the interpretation of the metrics derived from Fitts\u2019 law. Ten children aged between 6 and 8 participated in this study. Participants performed a series of pre- and post-training tests for both input devices. After the experiments, data were analyzed and statistically compared. The results show that Fitts\u2019 law can be used to detect changes in the learning process and assess the level of psychomotor development (by comparing the performance of adults and children). In addition, meaningful differences between the fine motor control (hand) and the gross motor control (head) were found by comparing the results of the interaction using the two devices. These findings suggest that Fitts\u2019 law metrics offer a reliable and objective way of measuring the progress of physical training or therapy.<\/jats:p>","DOI":"10.3390\/s21113826","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T23:33:33Z","timestamp":1622504013000},"page":"3826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Evaluation of Child\u2013Computer Interaction Using Fitts\u2019 Law: A Comparison between a Standard Computer Mouse and a Head Mouse"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3415-0088","authenticated-orcid":false,"given":"Cristina","family":"Sanchez","sequence":"first","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanina","family":"Costa","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4427-9579","authenticated-orcid":false,"given":"Rodrigo","family":"Garcia-Carmona","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3385-5307","authenticated-orcid":false,"given":"Eloy","family":"Urendes","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7699-5620","authenticated-orcid":false,"given":"Javier","family":"Tejedor","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7176-6984","authenticated-orcid":false,"given":"Rafael","family":"Raya","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n, Escuela Polit\u00e9cnica Superior, Universidad San Pablo-CEU, CEU Universities, 28668 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Read, J.C., and Bekker, M.M.
