Physicality and Usability Guidelines to Overcome the Interaction Complexities


Objectives: To develop the physicality and usability guidelines to reduce the interaction complexities and the cognitive burden on the users. Methods/Statistical Analysis: The study is conducted on the kitchen appliances. Three case studies were conducted on different kitchen appliances. Forty to fifty participants were selected from different age group, qualification, and cities. The data were collected from the participant on the bases of pretest and posttest questionnaire and direct observation method. The study was divided into two phases i.e. formulation of guidelines and comparative analysis. The study I and study II were used for guideline formulation and study III provided a comparative analysis. The qualitative research paradigms were employed for data analysis. Findings: Based on the data analysis, the new guidelines were proposed and evaluated in terms of physicality principles and usability components. Subsequently, t-test was used to validate, evaluate, and compare the results against ISO and IEC. This research has showed that the proposed physicality and usability guidelines are helpful in overcoming interaction complexities, reducing cognitive burden, and saving time. Application/Improvements: The data analysis showed that the proposed guidelines will improve the user experience by 94% and 85% in the physicality and usability of the kitchen appliances, respectively. The proposed guidelines can be employed in improving the design of these appliances to overcome interaction complexities.
