On January 20, 2025, a Blindfold test was administered by the members of "Project Wings to Dreams" to assess the design of tactile 3D models made for students with visual disabilities. The blindfold testing was carried out by three of the non-computer team from BA department, where participants were guided to evaluate models of Parts of Leaf, Nucleus of Cell & Constellation.

This session not only highlighted the accessibility of these models but also provided valuable feedback to enhance their design. From difficulties in distinguishing textures to challenges in navigating Braille labeling, the findings revealed areas for improvement, making the models even more user-friendly and effective.

The "Nucleus of the Cell" model, designed to educate about the nucleus's importance as the cell's core, was well-received but required adjustments. For example, participants faced challenges with the uneven surfaces and similar textures of the nuclear membrane and nucleoplasm.

Meanwhile, the "Parts of a Leaf" model, aimed at explaining leaf's parts and venation, revealed that transitioning between model sections was complex, and Braille integration needed refinement. Feedback suggested that using uniform textures for labeling and making walkthroughs more intuitive could significantly improve the learning experience.

The "Constellation" model was designed to help students with visual disabilities understand star patterns like Ursa Major and Draco. It included tactile elements such as ropes, beads, and Braille-labeled cards. Participants found the small tactile replicas helpful in understanding the shapes and structures of the constellations. However, some confusion arose regarding the starting points and the use of different textures. Feedback suggested making the replicas larger and refining the walkthrough instructions for better clarity.

Overall, the workshop showcased the importance of creating accessible learning tools. It highlighted the successes of the models while pointing out areas for improvement. These insights will help make educational resources more effective and inclusive for students with visual disabilities.
