Enabling Touchless Interfaces for Mobile Platform: State of the Art and Future Trends

摘要

In this work, we discuss the existing methods to implement and use a touchless gesture-based interaction on mobile platforms such as smartphones and tablets, specifically for situations where you cannot have a direct interaction with devices. The purpose of this work is to investigate the actual solutions and establish the most convenient way to enable these interactions on mobile devices with minimally-invasive procedures. The paper is organized in three parts: a survey of the current technological possibilities; a description of trials made to know advantages and limitations of the existing solutions; a final discussion concerning the evolution of the natural user interface on mobile platforms in the next few years.
