ABSTRACT
We present Ambient Gestures, a novel gesture-basedsystem designed to support ubiquitous ‘in the environment’interactions with everyday 代写留学生论文computing technology. Handgestures and audio feedback allow users to controlcomputer applications without reliance on a graphical userinterface, and without having to switch from the context ofa non-computer task to the context of the computer. The
Ambient Gestures system is composed of a visionrecognition software application, a set of gestures to beprocessed by a scripting application and a navigation andselection application that is controlled by the gestures. Thissystem allows us to explore gestures as the primary meansof interaction within a multimodal, multimediaenvironment. In this paper we describe the AmbientGestures system, define the gestures and the interactionsthat can be achieved in this environment and present aformative study of the system. We conclude with adiscussion of our https://www.51lunwen.org/computer/findings and future applications ofAmbient Gestures in ubiquitous computing.

INTRODUCTION
In this paper we present Ambient Gestures (AG), alightweight system that combines free hand gestures in
one’s environment with audio feedback to enable control ofcomputer applications ‘in the environment’. Standard
computing for the most part still requires users to go to acomputer’s context (physical location) to operate it.
Ambient Gestures’ ‘in the environment’ interaction isdesigned to support the ubiquitous computing goal of“transparent” interactions in a multimodal environment [18,33] enabling people to engage with a computer system,
more or less device-free, from theirs and not the computer’scurrent context (Figure 1).
The Ambient Gestures system is composed of a visionrecognition software application, a set of gestures to be
processed by a scripting application and a navigation and
selection application that is controlled by the gestures.With Ambient Gestures, hand gestures ‘in the environment’are picked up by the vision system and produce audioresponses in the form of earcons, text-to-speech, and Musicor spoken word audio as determined by the applicationbeing controlled. The audio feedback is used to guidenavigation and selection tasks within an AG-awareapplication.
Figure 1: Ambient Gestures supports ’in theenvironment’ system interaction so that users do nothave to change their current task context in order tooperate a computer application. Here, while washing up,gestures to the camera (circled in red) control a music
browsing software application.Gesturing in a non-visual interaction space has been shownto be effective: Schmandt, Brewster and Pirhonen [9, 22,
25] have recently demonstrated that there are advantages tointeracting with a hand-held computer in mobile situations
using only finger and button based gestures with audio-onlyfeedback for both textual and music audio information.Ambient Gestures extends the above work to includegestures that do not require physical contact with a devicein order to control and select information presentation.Figure 2: A mapping of gesture research along four dimensions: X is gesture type Y is device type, colou本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
