Presented model expands the bi-directional interface for human-computer interaction. It broadens the communication channel from a man towards a computer. This is achieved by using a digital camera devices in the HCI interface and the use of novel (taken from the literature) image analysis. Proposed interface use the full bandwidth video channel, thereby increasing the interface adaptability skills...
Due to the improvements in computer technology, interaction between computer and human has been evolved from command-line based interfaces to natural user interfaces that enables interaction in a more human-human way such as by speech, hand and body gestures, facial expressions and eye gaze. In this study controlling three dimensional images with gestures and speech using a three dimensional depth...
Controlling the home appliances and electronics gadgets through an Infrared remote control is now in general. But the same controlling tasks can be done more easily. Primary motive of proposing the new system of hand gesture remote control is to remove the need to look in to the hand held remote and to search for a specific key for specific function. This paper presents a novel system to control home...
This paper discusses the user-centered design process of developing a gesture-based interaction technology aimed at interacting with three-dimensional displays at short working distances (e.g., at arm's length). First, we explored the range and variability of gestures that come natural for users when interacting with 3D displays. The next section describes the challenges encountered when implementing...
Over the years the techniques and methods that have been used to interact with the computers have evolved significantly. From the primitive use of punch cards to the latest touch screen panels we can see the vast improvement in interaction with the system. The same applies to the projection technology for creating various geometric displays. Researchers are exploring new ways of projection and interaction...
In this paper, an face-tracking camera-based assistive technology is presented for extracting head and face based gestures which are delivered to individuals who are blind. The interface is capable of tracking the head and face of an interaction partner and delivering them through the recently developed VibroGlove interface. The construction of the interface as well as its application are detailed.
Recently, multi-touch tabletop displays provided the Natural User Interface (NUI). Humans use the bare finger as a pointing device for manipulation of interactive elements on multi-touch surface. However, fingertip size occupies the large space instead of appropriate target point and creates ambiguity in touch detection. To overcome issue possibly, we develop an optical multi-touch screen using the...
The paper presents a prototype of a system which can be used as a therapeutic and educational tool for children with developmental problems. Natural body movements and gestures are used in the system to interact with virtual objects displayed on the screen. Nowadays such systems can be easily built with the use of widely available free software tools for both graphical and vision applications. Such...
Although multi-touch technology is currently a research focus in the field of Human-Computer Interaction, its relative research, however, is still comparatively few in China. In this paper, several foreign multi-touch technologies based on senor and computer vision are introduced and the advantages and disadvantages of these technologies are analyzed briefly. It is important for studying the technology...
We report qualitative consumer field trials of a prototype digital memory device known as SenseCam. We presented SenseCam to 25 consumers in the US (N=9), Japan (N=8), and South Korea (N=8) to determine initial interest and expected use cases. This was followed by respondents using an actual prototype camera for approximately one week and reporting on their experience. Actual use cases differed substantially...
In this paper, a multi-touch analyzing algorithm is presented to meet the requirements of the educational application. The proposed algorithm is designed for the purpose of multi-camera, high efficiency and low CPU consumption, which includes background image accumulation, blob recognition, blob tracking, multi-camera collaborative process, data fusion and blob track post processing algorithm etc...
Current multi-touch display applications are mostly based on blob interaction. Fingers are treated as blobs, acting like some ldquomulti-pointrdquo interaction agents. No association between hand, fingers and blob IDs is usually provided. In this article we have described a solution for this problem that allows new applications ranging from games to innovative ways for interacting with multi-touch...
The personal computer is quickly becoming the center of an all-encompassing multimedia environment. An environment that spans information creation and exchange, entertainment, and near real-life experiential environment manipulation. With such a deluge of media experiences, a new Human-Computer Interface is needed to allow the user better direct manipulation of presented information. In this paper,...
With the development of virtual studio technology, the application in the field of education has been emerging in China, especially for high-quality educational resource authoring. However traditional virtual studio systems have not been widely deployed. The reason is not only the large investment but also the complexity of the operation and maintenance of the system. Thus new virtual studio system...
An eye-gaze tracking system-EyeSecret for real scene, is developed based on pupil-cornea reflection vector method. The general structure and software design are introduced. In the hardware of EyeSecret, design and optimization of optical system and control circuits were proposed. In the software, implementation algorithms of key modules, cornea reflection detection, pupil center extraction and calibration,...
This paper presents an eye-gaze tracking system based on the image processing. All the computations are performed in software and the system just needs a PC camera attached to the user's computer. We first extract the facial regions form the images using the skin-color model and connected-component analysis. Then the eye regions are detected by employing the rules and area segmentation. After the...
We propose an arm-navigation assisting system for a visually impaired person to reach an object on the table by indicating simultaneously ldquoclock positionrdquo of the object and the velocity of the clutching arm(hand) by the pitch of the signal sound. To assist real-time navigation we have adopted optical tracking of marks attached both on the hand and objects instead of scene analysis. The velocity...
