Winsor McKoi Interactive Fish Project is an experiment in delight and engagement. Using gesture-based, haptic technologies and holographic display, the interactive window-front installation presents an animated origami fish. Named for cartoonist and early animator Winsor McCay, Winsor McKoi (the virtual fish) responds in real-time to physical presence and gestures, transitioning from shy state (at the back of the display) to a curious state (in the foreground of the display). From a project-based Twitter account, Winsor McKoi registers hashtag pings and tweets status updates (including “sadness” warnings indicating lack of interaction), thus encouraging in an audience continued interaction with Winsor McKoi while away from the physical site of the installation. Ultimately, the project endeavors to cultivate a community of participants who actively maintain the “life,” that is, animation of the virtual fish over time. The project’s interaction design is inspired by the 1990s popular Japanese digital Tamagotchi pet.
