Gesture Sensor for Mobile Devices

Contactless Gesture Recognition for Mobile Devices

While gesture interfaces become pervasive, most existing approaches are undesirable for mobile devices because of the high power consumption, or the inconvenience that users need to wear/hold specific sensors. In this paper, we present a contactless gesture recognition system for mobile devices using proximity sensors. A set of infrared signal feature extraction methods and a decision-tree-base...

Gesture Interfaces for Mobile Devices – Minimalist Approach for Haptic Interaction

Due to the limited input and output functionalities and varying usage situations, haptics offers a potential approach for interacting with mobile handheld devices. In this paper, we discuss the specific features related to haptic interaction methods for mobile devices and argue for a minimalistic gesture control. In addition, the paper presents a haptic mobile phone application utilizing this d...

Creating a Database for Objective Comparison of Gesture Recognition Systems

In the past decade, accelerometer sensors became small enough to embed in mobile devices that people are using every day. Thus, arm movements became attractive to control mobile games and game consoles. However, there is no widely-used gesture-vocabulary for controlling devices and gesture recognition is not standardized. Furthermore, there is no widely-accepted benchmark for measuring performa...

Demo: E-Gesture – A Collaborative Architecture for Energy-efficient Gesture Recognition with Hand-worn Sensor and Mobile Devices

Orientation-based Interaction for Mobile Devices

Our team has been exploring the possibilities of orientationbased sensors on mobile devices. We constructed a prototype system for delivering 3D acceleration and magnetic compass data to a Pocket PC and developed trial applications. One class of applications relied on the tilt sensors to provide a gesture interface to an application. A second class of applications used the magnetic sensors to c...
