This is according to the main findings of the \u2018Ergonomic Evaluation of 3D Mice\u2019, a study conducted by the Fraunhofer Institute for Industrial Engineering (Fraunhofer-Institut f\u00fcr Arbeitswirtschaft und Organisation) on behalf of <a href=\"http:\/\/www.3dconnexion.eu?utm_source=press&amp;utm_medium=release&amp;utm_campaign=ergonomics\" target=\"_blank\" rel=\"noopener\">3Dconnexion.<\/a><img decoding=\"async\" loading=\"lazy\" class=\"alignleft size-medium wp-image-13858\" src=\"https:\/\/www.soundpr.it\/wp-content\/uploads\/2019\/07\/Ergonomics_with_SpaceMouse_Comparison_01-300x141.jpg\" alt=\"\" width=\"300\" height=\"141\" \/><\/p>\n<p>The use of 3D mice allows a two-handed workflow in the CAD, CAE and CAM environment. A 3D mouse enables users to pan, zoom and rotate their models in one smooth movement using one hand, while they edit their models using a standard mouse with the other hand. 3Dconnexion, a manufacturer of ergonomic input devices for CAD and 3D professionals, commissioned the Fraunhofer Institute for Industrial Engineering (IAO) to carry out a scientific study on working with a 3D mouse. The study consisted of two parts\u00a0\u2013 a laboratory test and a field test across which there were a total of 24 participants\u00a0\u2013 and focussed on the criteria of health, productivity, usability and user experience when performing a specific CAD task with and without a 3D mouse.<\/p>\n<p><strong>Superior ergonomics with a 3D mouse<\/strong><\/p>\n<p>The investigation revealed that using a 3D mouse leads to a more upright and thus healthier sitting posture. The main reason for this is that both arms rest in parallel to one another on the desk while working in a CAD program. The right hand-arm-system bears significantly less strain as this is spread across both hands thanks to the 3D mouse assuming tasks that would have been performed with the right hand using a normal mouse.<\/p>\n<p>Using a 3D mouse also substantially reduces the number of mouse wheel movements, for example, when zooming in and out of a model, meaning 29\u00a0per\u00a0cent fewer hand and finger movements are required. According to Fraunhofer, this has caused \u201cthe finger movements to drop from a \u2018dangerous\u2019 level (over 1,500 movements per hour) to an acceptable amount.\u201d<\/p>\n<p><strong>User experience improves with a 3D mouse<\/strong><\/p>\n<p>The 3Dconnexion SpaceMouse also impressed in terms of user experience. A usability analysis was carried out during the field study using a System Usability Scale (SUS) questionnaire (2) in which the SpaceMouse achieved an excellent SUS score of 86. In contrast, conventional workflows with a normal mouse and keyboard only achieved a satisfactory SUS score of 62 in terms of usability.<\/p>\n<p><strong>3D mice increase productivity<\/strong><\/p>\n<p>Finally, the use of a 3D mouse led to a significant increase in productivity. In the laboratory study, the amount of time needed to complete a random task was reduced by 28\u00a0per\u00a0cent\u00a0\u2013 from 96\u00a0minutes to 68\u00a0minutes\u00a0\u2013 when using the 3D mouse.<\/p>\n<p>\u201cThe use of our SpaceMouse leads to a healthier posture and reduces the strain on the dominant hand-arm-system. It features a high level of usability and increases productivity when working with CAD programs,\u201d explains Robert Stadie, Product Manager at 3Dconnexion GmbH. \u201cWe are pleased that Fraunhofer\u2019s intensive testing has provided conclusive evidence to this end. This is also motivation for us to continue down the path we have embarked on in developing innovative 3D mice.\u201d<\/p>\n<p><strong>Methodology<\/strong><\/p>\n<p>Fraunhofer conducted both a laboratory and a field investigation as part of the study. The laboratory test saw 14 students from an advanced CAD seminar analyse factors related to health and productivity. For the test, the participants had to complete a standardised and randomised CAD task in Siemens PLM-Software NX&#x2122;, once using a standard mouse and keyboard and once using a 3D mouse and a standard mouse. Every movement and click was recorded and posture was observed while the task was being performed.<\/p>\n<p>For the field test, ten experienced CAD professionals took part in semi-structured interviews and the standardised, validated SUS and AttrakDiff (3) questionnaires were used. Working \u2018with and without a 3D mouse\u2019 were both examined here.<\/p>\n<p>(1) The \u2018Ergonomic Evaluation of 3D Mice\u2019 investigation report from the Fraunhofer Institute for Industrial Engineering (IAO) can be found at <a href=\"https:\/\/www.3dconnexion.eu\/ergonomics\/eu?utm_source=press&amp;utm_medium=release&amp;utm_campaign=ergonomics\" target=\"_blank\" rel=\"noopener\">https:\/\/www.3dconnexion.eu\/ergonomics\/eu<\/a><\/p>\n<p>(2) The System Usability Scale (SUS) is a \u2018quick and dirty\u2019 method of measuring the usability of an application developed by John Brooke in 1986. The SUS scale goes from 0 to 100. Solutions with a score of 68 and above are considered to have good usability.<\/p>\n<p>(3) The AttrakDiff questionnaire is an evaluation of any product to assess how attractive the product is and to what level it offers a good user experience. AttrakDiff was developed by Marc Hassenzahl, Michael Burmester and Franz Koller in 2003.<\/p>","protected":false},"featured_media":17227,"template":"","news_categories":[192],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Fraunhofer study \u2013 The use of 3D mice improves ergonomics at CAD workstations - soundPR<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.soundpr.it\/news\/uno-studio-del-fraunhofer-institute-for-industrial-engineering-dimostra-come-lutilizzo-di-mouse-3d-migliori-lergonomia-per-gli-utenti-di-workstation-cad\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"[:it]Uno studio del Fraunhofer Institute for Industrial Engineering dimostra come l\u2019utilizzo di mouse 3D migliori l\u2019ergonomia per gli utenti di workstation CAD[:en]Fraunhofer study \u2013 The use of 3D mice improves ergonomics at CAD workstations[:] - soundPR\" \/>\n<meta property=\"og:description\" content=\"The use of a 3D mouse in CAD applications leads to a noticeable ergonomic improvement with the user making 29\u00a0percent fewer hand movements and their productivity increasing by 28\u00a0per\u00a0cent.
