    Exploring the Poka-Yoke Concept as an extended usability criterion for age-friendly kitchen design
    (2024-05) Aydıngün, Gülçin
    This study proposes the Poka-Yoke Concept as a usability criterion for the improvement of residential kitchen design for older adults, using aging simulation suit (GERT suit). Thesis includes two separate study datasets. In the first data set, 152 older adults from the Geriatrics Department of Hacettepe Hospital participated to fill out the questionnaire. According to the results, error prevention, low physical effort, adequacy of lighting and workstation were the most important kitchen design criteria. In the second data set, tasks and scenarios were conducted with architects and interior architetcts using the kitchen of Bilkent University Graduate Housing. As a result of the heuristic evaluation adapted in the context of Poka-Yoke Concept, it can be used as a usability criterion by increasing empathy towards older adults with GERT simulation.

    Influence of simulated physical ageing on heuristic evaluation in airport environments
    (2019-05) Yumuşak, İrem
    This thesis suggests a new approach for the heuristic evaluation of an airport environment by using simulated physical ageing. A task-based heuristic evaluation method was conducted with the eight evaluators who were professionally working as architects and interior architects. A real airport environment was selected as the experiment building where the evaluators performed task scenarios in line with the real airport experiences of passengers. Four evaluators wore GERT suit and four evaluators did not wear GERT suit to analyze the influence of simulated physical ageing. According to the results, the findings indicated that GERT suit enabled a better inspection of usability of an airport environment, an increased level of physical performance difficulty and enhanced empathy towards elderly people.
