Title: 3D Planetary Model of Solar System for Visually Impaired Person: Basic Astronomy Education for Disabilities
The development of astronomical technologies had been advanced rapidly every once days. Every astronomical technologies can discovery and explain something in universe. Other function at astronomical technologies is an outreach technology. Outreach technology make astronomy education would be digested and realized by society especially for visual impaired person. Nowdays, visual impaired person doesnft have many media to learn astronomy at solar system planets. Therefore, it necessary to make a solar system learning tools for visually impaired person that named g3D Planetary Model of Solar Systemh. The method was using research and development and literature based study. These tools was used eight planets and sun as a learning model that shaped heliocentric. When the planet was touched at the northern polar point of planet, visual impaired person would know the position planet with earth perspective. Overall, itfs using the sense of hearing and touch by touching the object of a planet and listening to the description of the planet. The schematic tools consist of mechanical and electric schematic. Mechanical schematic using modified solar system module that form squared and each of planets have to push button for learning that. Electrical schematic using capacitive touch sensor TTP223 as an input module, Arduino Mega2560 as processing module, speaker module as output module, and adaptor. Besides that, this tool had several features that help visually impaired people such as an explanation button on how to use the tool. Before being used for visual impaired person, operator calibrating a real position of planet in heliocentric form. Next, visual impaired person press the button at the north pole of the planet. Then, button that connected to TTP223 will recognize and send data to Arduino Mega 2560 for processing before went through to output speaker module for explain the data description from input device.
