SmArt WhiteBoard Replacement Interactive Device (SAWBRID) Enhancements and Optimizations

Communication between the professor and student are key to a successful learning experience. However, it can be difficult at times to schedule a meeting with a professor. The SmArt WhiteBoard Replacement Interactive Device (SAWBRID) is a system that facilitates the communication between professors and students. The system is composed an E- Paper device that mounts outside a professor's office and a mobile application. The E-paper device displays a professor's availability, scheduled meetings, and communicates messages such as being a little late for office hours. The mobile application allows students to check different professor's availability and schedule an appointment with their professor. It also allows professors to connect the system to their calendar, update their schedule, and relay messages to be displayed on the E-paper. The professors' and students' data are stored on an in house server. In this research we focus on providing a smooth user experience with the SAWBRID system as well as providing a fully secure communication channel using public-key and aecret-key encryption to ensure confidentiality and hash functions to ensure data and user integrity. The system will be evaluated for usability, security, and power and energy consumption.
