The visual analysis efficiency also depends on the human-computer interactions, to manipulate and inspect the volume data. This research aims to develop an interactive visualization system using a head-mounted display to analyze three-dimensional volume data, and hands-motions sensor to realize the interactive operations.
The past few years has shown a sudden spurt in the field of human computer interaction. The days of using a mouse to control a computer is almost obsolete and people now prefer to use touch screens and more recently, air gestures, for the same. However, the use of gestures is not limited to computers alone. It finds its application in controlling televisions and other home appliances as well. This...
A simple and robust gesture recognition system is proposed for better human-computer interaction using Microsoft's Kinect sensor. The Kinect is employed to construct skeletons for a subject in the 3D space using twenty body joint coordinates. From this skeletal information, ten joints are required and six triangles have been constructed along with six respective centroids. The feature space corresponds...
User experience has gained great attention in recent years, and with rapid change in technology, understanding user's emotions and whether or not they are happy has become crucial, in order to offer better solutions and experience to the user. This paper presents a synthesis of affective computing research on frustration detection in interactive systems. Two tabletop systems for hand gesture frustration...
We present the design and evaluation of Air Touch, a wristwatch interface that enables mobile gesture interaction through tactile feedback during limited visual attention conditions. Unlike its predecessor, the Gesture Watch, Air Touch is supported by a push-to-gesture mechanism (PTG) where the user performs a gesture and then confirms it afterward with a trigger gesture. The Gesture Watch, in contrast,...
Hand pose recognition has been a problem of great interest to the Computer Vision and Human Computer Interaction community for many years and the current solutions either require additional accessories at the user end or enormous computation time. These limitations arise mainly due to the high dexterity of human hand and occlusions created in the limited view of the camera. This work utilizes the...
This paper deals with the development of high performance real-time system for complex dynamic gesture recognition. The various motion features are extracted from the video frames which are used by HMM classifier. We used several clustering techniques for performance evaluation of the classifier. Our system vectorises gestures into sequential symbols both for training and testing. We found very encouraging...
Interactive displays are increasingly being distributed in a broad spectrum of everyday life environments: they have very diverse form factors and portability characteristics, support a variety of interaction techniques, and can be used by a variable number of people. The coupling of multiple displays creates an interactive “ecosystem of displays”. Such an ecosystem is suitable for particular social...
Ubiquitous computing, or pervasive computing, is an increasing popular technique for developing new human-computer interfaces and computer applications. Computers watch what happens in a physical space where people are and serve them with meaningful information. Here, most of the systems depend on visual interaction, while there are some other interaction media. In this paper we present a collaborative...
