An intuitive data transfer technique using bartender's gestures.

This technical demonstration presents Cocktail, a gesture-based mobile interaction system, which is designed for providing a user-friendly way of exchanging multimedia data with intuitive gestures. Our system is motivated by bartenders who make cocktails with interesting gestures, such as pouring and shaking. These gestures are used in our interaction system for data transfer and contents creation: a user can pour (transfer) data in his/her mobile phone to other devices in the same way that a bartender pours drinks to a shaker. The user can also mix music files and pictures into a multimedia content, such as a music video file, by shaking the mobile phone, as a bartender does to mix different drinks into a cocktail. We have implemented a prototype of Cocktail using smart phones and demonstrate its usability.
