Designing a Big Screen Interaction Based on Smartphone Touch Gestures

摘要

Advances in computer systems lead to the pervasiveness of computer systems in our surrounding (e.g., open spaces, malls). Those computers are often equipped with big screens and various input devices (e.g., keyboards, joystics, mouses, touchscreens) to interact with. Though smartphone has been ubiquitous and equipped with various input means and sensors, it is quite rare to use them to interact with a big screen. In this paper, we explore a design space of touch geastures in a smartphone for users interacting with a big screen via their smartphones. We conduct various experiments various geatures and studies how a finger interacts with the smartphone's touchscreen and maps it to a big screen interaction. Those geasutres are tap, double tap, drag, flick, spread, pinch and rotate. To validate our interaction design, we conduct users' experiments interacting with a big screen using an object with various size. Those results, then compare with a mouse with the same interaction. Though, experiment results show our interaction design worse than the ones with mouse. It shows promising results to be further developed so that bring your own device interaction in a public place with a big screen can become a user-friendly reality.
