Exploring inclusive design criteria for the vision impaired students in Dhaka university campus

Abstract

Ensuring accessibility and spatial planning in educational institutions is vital for students with vision impairments. Research indicates the challenges these students face on campus and the importance of inclusive design solutions. This study focuses on establishing inclusive design criteria for creating accessible university campuses, using Dhaka University as a case study. It examines the routes from residential halls to academic buildings for residential students with visual impairments. The research approach included a thorough field survey to identify barriers along the selected routes. Subsequently, a behavior observation was conducted and a close-ended questionnaire was administered with a five-point Likert scale. Through the behavior observations, the study identified navigation challenges faced by visually impaired students. The questionnaire survey provided valuable feedback on personal orientation and mobility skills, utilization of non-visual senses during navigation, as well as the physical, informational, and cognitive barriers encountered within the campus. Later a correlation analysis was conducted to comprehend the influence of these factors on navigation challenges. Additionally, from focus group discussion, specific qualitative feedback on barriers, the use of non-visual senses, and the effectiveness of assistance were gathers. Furthermore, participants shared potential interventions to address the barriers they encounter on the Dhaka University campus. Based on the research findings, several key barriers were identified that impact participants, particularly concerning parking, building entrances, and physical obstructions along pathways termed as physical barriers. These findings provide valuable insights that can guide us in addressing these challenges to create a more accessible environment for all students. It's important to consider the impact of these barriers, especially on female students, and to work towards implementing solutions that will enhance accessibility and improve the overall experience for everyone. Additionally, the research highlights the significance of non-visual signage and path layout in addressing information and cognitive barriers, offering us opportunities to make meaningful improvements in these areas. Later a set of inclusive design guidelines are proposed in the selected site of Dhaka University campus. It will help architects, designers and planners for further designing and planning an inclusive campus . Finally, The research outcome will support to achieve sustainable goal-4 by ensuring inclusive and equitable quality higher education and promoting lifelong learning opportunities for visually impaired students.
