OVERVIEW<\/strong><\/p>\n\n\n\n

A study was conducted to develop design criteria by asking a questionnaire and observing groups of professional designers who work with design, graphic, animation, and engineering softwares.<\/p>\n\n\n\n

Hand major motions and its relation with CTS<\/strong>
Faraji & Farahmand express four motions that are predictable within an interaction between a user\u2019s hand and a regular computer mouse:
\u2022 Pronation of forearm;
\u2022 Ulnar and radial deviation of wrist;
\u2022 Dorsi flexion of wrist;
\u2022 Extension, bending and lateral motions of fingers.<\/span><\/p>\n\n\n\n

\u201cIf these motions exceed the excessive values, it leads to WMSDs in upper limbs. In fact these excessive situations will increase the carpal tunnel pressure\u201d. <\/em>-Faraji, A., & Farahmand, M. R. (2013).<\/p>\n\n\n\n

STUDY<\/strong><\/p>\n\n\n\n

The study was broken up into categories group A being Designers working with Design, Graphic, and animation softwares, Group B being designers working with Other sofwares and Group C being Designers working with engineering softwares. Sub groups (Example A-1, A-2 etc..) were also made.<\/p>\n\n\n\n

Designers working with Design, Graphic, and animation softwares
(group A) [Insighst]<\/strong><\/strong><\/p>\n<\/div><\/div>\n\n\n\n

” Sub group \u201cA-1\u201d consists of users who work professionally with graphic design softwares like <\/em>Photoshop, 3ds max, Maya, Corel draw, etc. When they are working with their specialized softwares, they use keyboard very few (while have lifted their hand from mouse) and grip the mouse continuously for long time.<\/em>“<\/span><\/p>\n\n\n\n

“Sub group \u201cA-2\u201d consists of users who work professionally with engineering design softwares like AutoCAD, Solid works, Catia, Rhinoceros, Alias studio tools, etc. In comparison with previous sub group, this one has more keyboard use for data and dimension entering.”<\/span><\/em><\/p>\n\n\n\n

Other (Students, employees, secretaries etc..) (Group B)<\/strong> [insights]<\/strong><\/p>\n\n\n\n

Rather than spending long periods of time with a specific program, this group would usually spend long hours over multiple applications (Ex, Word, PowerPoint, etc..) <\/p>\n\n\n\n

Designers working with engineering softwares
(group C) [Insighst]<\/strong><\/strong><\/p>\n\n\n\n

“Users of group \u201cC\u201d use engineering softwares like C++, Matlab, Spss, Etabs, MS project, Primavera, Minitab and so forth. In this group mouse use is far less than sub group \u201cA-2\u201d. In this softwares data and text entering with keyboard is much more than design, graphic and animation softwares.”<\/span><\/em><\/p>\n\n\n\n

MAJOR TAKEAWAYS<\/strong><\/p>\n\n\n\n

The following is a list of design criteria that this study created by assessing the questionnaire given to users:<\/p>\n\n\n\n

“Ergonomic criteria<\/strong>
\u2022 Decreasing or eliminating the wrist deviations as ulnar and radial deviation and dorsiflexion;
\u2022 Prevention of user for controlling the mouse by leaning his hand on top of the desk;
\u2022 Considering a supporting surface for wrist that preventing callus creation on the skin of this region;
\u2022 Preventing forearm from pronating with excessive angles;
\u2022 Preventing from Static and powerful grips;
\u2022 Prevention of user\u2019s fingers bending, stretching or lifting up while clicking;
\u2022 Following the product\u2019s form from the form of user\u2019s hand and being non-symmetrical;
\u2022 The mouse size and the user\u2019s hand size being equal; Applied Mechanics and Materials Vol. 440 195
\u2022 The mouse key possessing enough length to cover the users\u2019 hand size difference and fingers position in relation with it;
\u2022 Designing a right hand mouse for left-hand users;
\u2022 Designing the surfaces that are in touch with user\u2019s palm, somehow that preventing user\u2019s palm from perspiration;
\u2022 Restriction of the Index finger for left click and scrolling and the Middle finger for right click. Functional criteria
\u2022 User quick ability in interaction with keyboard and no time consuming mouse grip;
\u2022 Accuracy decreasing that happening in mouse control by forearm, compensating with some arrangements;
\u2022 The keys position being somehow that does not active accidentally;
\u2022 Cursor possessing maximum movement with minimum scroll wheel rotation;
\u2022 Designed mouse must be light and portable;
\u2022 Designed mouse must not have additional keys;
\u2022 Designed mouse must be cordless;
\u2022 Final product price should be maximum 20 Euros. Aesthetical criteria
\u2022 Product gestalt should not be very strange or very innovative to make rejection in customers;
\u2022 Product dominant color should be black, particularly in areas that are in touch with user\u2019s hand;
\u2022 Product gestalt should induce professional sense, modernity and being lovely.”<\/p>\n\n\n\n
