Design of interactive and ergonomic wheelchair equipped with direct health service system accessibility

An interactive and ergonomic wheelchair equipped with a health service system has been designed. Its primary goal is to meet the mobility of the different persons with disabilities. At the same time, its secondary goal is to provide novelty health services such as urination and defecation by observing the tips and health space. This research is applied in terms of purpose and qualitative-descriptive in terms of nature. As a practical matter, it has used two methods of verbal-visual (questionnaire, interview) and non-verbal (observation) by survey method to collect data and benefit from analysis by relevant expert (Delphi) groups. Its design method was the so-called Design up (Tarrahi Nameh in Persian) which was based on the interaction design and user-centered approach and has employed Analytical Hierarchy Process (AHP) to prioritize users. The result is the interactive and ergonomic wheelchair equipped with a health service system under the Sabita brand, which has an effective, efficient and safe means of transportation. It enjoys the sanitary system of defecation in a hygienic environment along with washing and purification, which is the main need of its users and finally seeks their satisfaction and pleasure. The Sabita wheelchair, also, facilitates the work of physically able-bodied assistants. Six elements of usability such as effectiveness, efficiency, safety/comfort, utility, learnability and memorability, on the one hand would be brought. The goals of interaction design as visibility, feedback, constraints, consistency, affordance and engagement user experience, on the other hand, would be illustrated.
