Abstract

User-experience (UX) design is the process of inclusion of user behavior and user perspective in a product. The process will proceed through usability, accessibility and desirability of users with a product. Magnification of the interaction with a product is the outcome of UX design. Understanding the relationship between end users and the product from the perspective of the system is simplified by citing the following experiment that was done in the Ergonomics Laboratory at the University of Calcutta. The cooking spatula is one of the main utensils in the kitchen. In using this spatula, users are facing lots of difficulties such as bending and twisting of the wrist, and repetitive movements. These may cause wrist discomfort and develop carpal tunnel syndrome. This cooking spatula has no bent angle (0°) and it has a straight handle, and hence this design leads to wrist bending postures of the users. The existing cooking spatula has less accessibility and desirability during cooking. Three different bent-handled spatulas (0.2 m × 20°, 0.2 m ×15°, 0.2 m× 25°) with handgrip (35°, 45° angle) were designed and given to the users for evaluation. From their responses, a final design (0.2 m, 20° bent angle and 35° handgrip angle) was selected for further studies. The betterment of wrist posture of the users is identified by the Rapid Entire Body Assessment and Individual Risk Assessment methods.
