   In this paper, we define a learning activity for an elementary physical education classroom that simultaneously engages students in physical activity while introducing students to basic principles of reinforcement learning. Reinforcement learning is a sub-domain of machine learning in which an independent agent (in our activity, a student) takes some action or series of actions and receives a reward for the chosen action(s). While reinforcement learning intuitively maps to many activities in our daily lives, our learning activity involves a spy game. Students create sequences of spy moves that generate rewards based on their component moves and the orders in which they are performed. Students then iteratively expand their spy moves in an attempt to receive the maximum reward. The construction of the game will demonstrate that the rewards, while deterministic, do not always follow a greedy pattern, introducing students to basic algorithmic principles. Such an approach that combines physical activity with reinforcement learning connects artificial intelligence education within the broader scope of computing and students’ everyday lives.

   This paper investigates a novel encryption key sharing mechanism using the emerging wireless technology Visible Light Communication (VLC). Based on the idea of transmitting data by modulating light, we are able to (1) share a secret key within a constrained physical space and (2) communicate encrypted information among co-located mobile devices using the shared key. We present the demonstration Jive (Joint Integration of VLC and Encryption), a framework to support secret key sharing over Visible Light Communication. In defining Jive, we tackle challenges related to data encoding, message synchronization, and environmental noise to build a reliable, low complexity system using off-the shelf hardware. Our system is capable of sending encryption keys at speeds of more than 750bps using ultra short, high speed light pulses imperceptible to the human eye. Additionally, we have developed an application for Android that interfaces with the VLC device through serial communication so that applications running on mobile devices can subsequently use the keys to encrypt application data. Experimental results illustrate the high accuracy of our system across a variety of different variables. Finally, we position our system for use by a variety of applications that require a high-level of data security among physically co-located devices.

   We present a demonstration of Jive (Joint Integration of VLC and Encryption), a novel encryption key sharing framework utilizing the emerging wireless technology Visible Light Communication (VLC). Based on the idea of transmitting data by modulating light, we are able to (1) share a secret key within a constrained physical space and (2) leverage this shared key to communicate encrypted information among co-located mobile devices. In this demonstration, we showcase our complete implementation of Jive: a VLC transmitter and a VLC receiver. Both endpoints are built using off-the-shelf components. The VLC link is used to distribute a randomly generated secret key that can only be "observed" by VLC receivers that are physically in the same space as the transmitter. Each receiver is connected over a serial connection to an Android device; we developed applications for Android that take the key from the VLC receiver and subsequently use the key to encrypt or decrypt application data. Our demo invites participants to create their own encrypted messages in the Android application and interact with the VLC prototype as it transmits encryption keys, thus illustrating our system’s ability to bootstrap security among physically co-located devices.
