The Perception of Usability, Ergonomics and Aesthetics for Three Different Types of Tin Snips
M.S Syed Mohamed


Upper limb disorders are frequently caused by excessive forces and awkward postures of the upper limbs. Improperly designed hand tools may lead to the application of excessive forces and awkward postures. Along with ergonomic and usability features, hand tool aesthetics might influence buying decisions. In this study, assessment of the perception of ergonomics, usability and aesthetics were taken for three different tin snips (x1, x2, and x3). Ninety two subjects (n=92) participated in the perception assessment. The Technology Acceptance Model (TAM) was utilized in order to assess usability, while the hand tool comfort descriptors were used to assess ergonomics. Results indicated that participants strongly preferred tin snip x3 over x1 and x2. In addition, tin snip x3 was rated as the most visually appealing hand tool. However, the correlation between perceived ergonomics, usability and aesthetics is very weak (r=0.09). Potential ramifications for users and designers are discussed.
