In this paper, aiming at the problem of imprecise localization and perturbation interference in the field of traditional large screen, large screen interactive system with projection technology is designed based on the affine transformation algorithm to realize the precise interactive region coordinate positioning. Any wall touch system of human-computer interaction has been obtained by the analysis...
We grew up interacting with the physical objects around us. And there are large number of them that we use everyday. These objects are more fun to use than our computing devices. Taking about objects, another thing that get's attached with objects is gestures; how we manipulate these objects & how we use them in everyday life. These gesture are used to interact with objects as well as to interact...
There are very few interfacing technologies to manipulate real-time behavior for operating computer systems. During a presentation, it is inconvenient to control the computer and simultaneously explain the topic. There are several alternatives like speech recognition, laser based gloves but these techniques are less portable and have less accuracy. Our system, interactive wall display, allows you...
In this paper, we describe a demonstration of remote collaboration system using Empathy glasses. Using our system, a local worker can share a view of their environment with a remote helper, as well as their gaze, facial expressions, and physiological signals. The remote user can send back visual cues via a see-through head mounted display to help them perform better on a real world task. The system...
ARM embedded system can achieve a higher degree of integration, it has the advantages of small volume and low power consumption, which has gradually become one of the important products of information industry. In this paper, we introduce the overall design scheme of ARM and software. We provide an efficient solution to meet the request of even text materials when using camera. To turn on the camera...
In a search and rescue scenario, an expeditious response is critical since the radius of the search area increases by roughly 3 km per hour while the life expectancy of the lost individual decreases. To find the object of the search as quickly as possible, the incident commander creates an overlay probability map identifying high priority search areas and develops a search plan that allocates search...
Serial number is a unique number given to a product which can be used for product identification and inventory management. Information about the product may be its manufacturing date, expiry date, place of manufacture and so on. Some companies use serial numbers to keep track on the number of products which a retailer is authorized to sell. Thus serial number identification becomes an important part...
Internet of things (IOT) can be considered as a combination of effective hardware and impressive software which results in smart objects which are able to communicate and interact among themselves. However, data flow accuracy between two movable devices is a growing problem. This paper proposes and implements two approaches: Discrete Cosine Transfer (DCT) and Inter-Process Communication (IPC) for...
This work present new approach eye tracking with very less expensive IR sensor & IR led based apparatus connected to the computer. Photodiode & phototransistor are light reflection based component, the system design by use these components can be called as light reflection based system or non-imaging sensor base system. Basically this system is having very low complexity & very low computational...
In order to solve the problem of the traditional intelligent mower, which cannot cover the lawn area and operate complexly, a visual, wireless, autonomous mower system via machine vision is designed. Firstly, collect the image information of locale dynamically by the real-time camera which erected on the high bracket, and display on the monitor of PC, then draw a few mowing range or mowing patterns...
With the advancements in the hardware technology, it is now possible to transmit data over Ethernet at the rate of 100Mbps/1Gbps. The only limiting factor for such a high peed data transfer is the speed of the processor in the computer which does all the TCP/IP processing by using the TCP/IP software written in it. In the present system, the IR sensor used is taking 50 images of plasma per second...
Stating that human touch sensing surfaces have revolutionized the era of human machine interaction is perhaps stating the obvious. It is a known fact that the invention of touch-screen has almost eradicated the so-called primary input device, “the keypad” or “the keyboard” from modern electronic gadgets. The technology used in order to sense the touch is noteworthy. It is broadly categorized as Resistive...
Target reporting plays an important role in firing accuracy test and exercitation of small arms. Since a long time, we have been relying on the traditional manually target reporting, whose disadvantage is big error and low efficiency. We construct a new automatic target reporting system by means of machine vision. It analyses the captured target image with image processing technology, outputs bullet...
A computer machine vision system that can be used for automatic high-speed fruit sorting and grading is proposed. The objective of the project is to develop the advanced quality control inspection system makes use of distributed network architecture to interface the camera unit to a computer system through GigE LAN environment in a flexible way. The development work activity involves in dynamic capturing...
In this paper, a novel framework for implicit sentiment image tagging and retrieval is presented, based on the concept of attributed affect. The user's affective response is recorded and analyzed to provide an appropriate affective label, while eye gaze is monitored in order to identify a specific object depicted in the scene, which is attributed as the cause of the user's current state of core affect...
The traditional human-computer interfaces demand good manual agility and refined motor control, which may be absent or unpredictable for people with certain disabilities. Here it is proposed a robust, accurate algorithm with relevant hardware setup to detect eyes and measure the duration of blinks to interpret them in real time to control a computer or computer interfaced devices. The complete system...
Surveillance cameras account for a large portion of the security devices market and are used in an increasing number of areas. Recently, surveillance cameras have been evolved into high performance intelligent surveillance camera systems using many image processing algorithms including face and object recognition, image reconstruction, super resolution, and tracking. Most image processing algorithms...
When a speaker stands in front of a projector screen for a presentation, the eyes will be hurt by the direct light from the digital projector. This paper proposes a design to reduce the strong light by projecting a black round mask on the speaker's head. The black round mask is superimposed to the slide frame by the software of this design and the mask traces the speaker's head. The depth camera captures...
In order to resolve crashed accidents caused by fatigue or drowsiness various fatigue detecting algorithms are investigated. Aiming at the needs of large data, high transfer rate and complex operation, in this paper, we design a fatigue detection algorithm based on PERCLOS, moreover, design AVT Guppy F-080 C camera and 1394 cards as the core hardware system. The system can meet the real-time video...
In this paper we examine how closely together images to be used in 3D reconstruction are captured, when acquisition is started using a software-based trigger delivered to multiple computers on a network. In addition we compare a software triggered pull system to a push system. Synchronisation is a key component in 3D reconstruction systems and can also be one of the most problematic. In a shape-from-silhouette...
