Supporting Collaboration in a Group Hackathon by Sharing States of Progress and Product Images Nishi Kohtaro1. Nishimoto Kazushi2. Abstract: This paper proposes a support system of a group hackathon named “HackathonMediator” to solve problems of collaboration in a team of hackathon. HackathonMediator consists of two functions: a function to share work screen among members for sharing states of progress and a function to create a mock-up model for sharing product images. We applied this system to an actual Hackathon event. Results of evaluation by behavioral observations and interviews are reported.. γϣφϧ΍ΞϚνϡΞɼϓϩάϥϚ΍σβΠφͳͲɼ༷ʑ. 1. ͸͡Ίʹ ۙ೥ɼϋοΧιϯʢHackathonɿHack-a-thonʣ*1. ͳٕೳ΍ٕྔΛ࣋ͭਓ͕ೖΓࠞ͡Δɽ൴Βͷ೔ৗ‫ۀ‬຿ʹ͓ ͱশ͞. ͚Δৗࣝ͸ɼϋοΧιϯνʔϜʹ͓͍ͯ௨༻͠ͳ͍ɽ.
