This is a short slideshow of an exhibition booth that we programmed for Heureka - the finnish science centre. The centerpiece is Pepper the robot by SoftBank Europe which worked as a reward for participants completing the quiz that was part of the experience. We made this network independent by using NFC cards to transfer and store data. Each participant was given an NFC card and then they used it to store their quiz answers. The quiz was realised using Raspberry Pis with official Pi touchscreens. A custom Linux kernel + filesystem was compiled to support WebGL and NFC reader (thanks to buildroot + WPE). The quiz runs on WebGL enabled WPE and a has node server with custom PCSCLite bridge to support NFC cards. Results for quiz were shown on a big screen running OSX and standard chrome (WebGL + node running NFC here also). Last part was the reward time with Pepper. We programmed Pepper to interact with users by telling more about the persona their quiz resulted in. The interactions also consisted of random behaviors greeting and reaching for people to come to the booth. On Pepper's tablet we had programmatical finnish subtitles that were in sync with Pepper's speech as well as other graphics running on Pixijs. We also crafted an administrator console for the innovators at the booth to initialize, store and manage NFC cards and their contents.
