| Abstract | This thesis documents the development of a new control method for Ralph Knowles Heliodon, owned by the School of Architecture, University of Southern California. The heliodon has been used to illustrate the solar impact upon architecture by using two manually controlled direct current motors that drive a light source on two tracks to simulate the position of the Sun at a certain time relative to a platform as the ground. In the new method, a Windows application with a user interface is developed to communicate with a circuit that can control a new pair of stepper motors that drive the light source to the target position, which is determined by the user input in the application. The new control method provides a conceptually clear and user-friendly way to operate the device and explores its potential function as an illustration tool. |
