Description
This study focuses on the design and development of a celestial sphere model that simulates the positions and movements of constellations, intended for both visually impaired individuals and those with normal vision. The device is suitable for visually impaired users with at least lower secondary education and for the general public who can distinguish directions. The design follows the Western cultural representation of constellations. The developed celestial sphere is designed for self-guided learning, allowing users to manually adjust and control its movements according to specific learning needs.
The model consists of a celestial sphere indicating the north and south celestial poles, a star map on the sphere's surface, and a raised celestial equator along the sphere's joint. All components are mounted on a circular base representing the horizon, with half of the sphere emerging above the horizontal plane. For visually impaired users, selected constellations are marked using circular acrylic stickers resembling Jewely seals in three different sizes to represent varying star brightness. Transparent plastic sheets with Braille labels indicate constellation names, directions, and usage instructions, placed on top of Thai text labels. The sphere can be adjusted to match the latitude of any location worldwide.
The model was tested with a group of visually impaired students from Redemptorist Vocational School for the Blind in Pattaya, Chonburi Province. The results showed that the students were able to identify the north and south celestial poles, horizon line, celestial equator, constellations, star map, and directions of rising and setting stars. For individuals with normal vision, the model also enhances understanding of celestial mechanics. The practical tests demonstrated that this educational tool is highly effective in supporting astronomy learning for both visually impaired and sighted users.
