It has been shown in numerous studies that the application of Augmented Reality (AR) to teaching and learning is beneficial, but determining the reasons behind its effectiveness, and in particular the characteristics of students for whom an AR is best suited, can bring forth new opportunities to integrate adaptive instruction and AR in the future. Through a quasi-experimental research design, our...
The growing availability of robotic platforms and open-source software presents a striking opportunity for the advancement of scientific instrumentation. Multirotors are particularly versatile platforms which offer some clear advantages for marine-based research missions including mapping and surveying of coastal, glacial, or marine features, photogrammetry, remote atmospheric or water sample collection,...
Visually Impaired (VI) and blind people suffer from reduced mobility, as they cannot detect the terrain and their environment. They always need assistance and walking support systems in their daily life. Solutions have been proposed many decades ago and are rapidly improving nowadays due to the technology evolution and integration. A large number of assistance aids have been deployed in real life...
The availability of hardware devices, applications and external connectivity in our computers and smartphones opens a wide range of opportunities for developing intelligent systems. People with some kind of motor disability can take advantage of such systems with minimal cost, as there are diverse hardware components already available in standard consumer products. Research reported in this document...
In this paper, we proposed tone mapping method which uses threshold function. It was impossible for conventional Multi-Scale Retinex algorithm to express detail parts due to damage in bright region of dynamic range at compression processing. We reduce the damage, which occurs in tone mapping process, by setting the threshold of Log Scale image in this algorithm. The experimental tests demonstrated...
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...
Though several assistive technologies are available for home-based rehabilitation of stroke patients, people are not using the same for several reasons. Lack of technical competence, chance of electrocution is some of such issues. The cables/ wires of different instruments, measuring devises, rehabilitation systems are often the source of infection; causes of electrocution, discomfort and immobility...
Intrinsic image decomposition is an important technique that decomposes an image into reflectance and shading components. In this paper, we enable intrinsic decomposition for stereoscopic images. Traditional approaches cannot be directly applied to decompose stereoscopic images, yielding inconsistent reflectance and 3D artifacts after recoloring. To solve this problem, we propose a straight yet effective...
The ability to open a door is essential for robots to perform home-serving and rescuing tasks. A substantial problem is to obtain the necessary parameters such as the width of the door and the length of the handle. Many researchers utilize computer vision techniques to extract the parameters automatically which lead to fine but not very stable results because of the complexity of the environment....
One of the important goals in Human Computer Interaction (HCI) is designing better and more intuitive interfaces for improving the interactions. There are lots of approaches to address this problem. One of these approaches is utilizing human hand gestures. The degree of freedom and complex structure of human hand however, make capturing and modeling of hand gestures a challenging problem. In this...
Nowadays, more and more online examinations are holden in the distributed examination centers, which calls for the deployment of examination surveillance systems. Various related techniques have been proposed for this purpose, for example, video surveillance, face recognition based identification, and etc. However, there is still a lack of flexible and scalable solution to detect the misbehavior of...
A mini quadrotor can be used in many applications, such as indoor airborne surveillance, payload delivery, and warehouse monitoring. In these applications, vision-based autonomous navigation is one of the most interesting research topics because precise navigation can be implemented based on vision analysis. However, pixel-based vision analysis approaches require a high-powered computer, which is...
This application is based on face recognition and facial features techniques to extract Regions Of Interest (ROI) by applying Haar filters and cascade classifier with OpenCV implemented in Visual Studio C#. Likewise, a software program was developed to transform blinkings into words, along with a graphical user interface, in which the spanish language alphabet letters and predifined phrases are displayed...
Due to its advantageous features (eye protection, low energy consumption and capability of being read under any lighting-conditions), Electrophoretic displays (EPD) have been rapidly developed in the past ten years. Different types or production batches of EPD films need different driving waveforms; even in the same device, different driving waveforms are required under different environments to guarantee...
High-speed camera can be implemented into a distributed camera network, which makes the camera network available to various dynamic applications such as observation at high speed and tracking of fast moving objects. This network system can be referred as high-speed distributed smart cameras (H-DSC). In order to construct a H-DSC, accurate synchronization between cameras as well as real-time feature...
At present, the edge-cutting of Wilton Carpet mainly rely on manual operation. Artificial cutting method has the disadvantages of low production efficiency, poor cutting quality, and is easy to be affected by human factors. The edge-cutting system with computer vision can overcome the disadvantages of manual cutting, but the existing systems have the disadvantages of high cost, low efficiency and...
For the forest, the fire is an extremely serious damage. In the forest fire point positioning research, it was found that the monocular vision system combination of digital elevation model(DEM) is a better way to locate fire position. However, this method has insufficient. This paper presents an improved monocular forest fire point positioning method on the grayscale bit plane. This way can make up...
Large lecture rooms typically contain more than one projector/screen pair, but the presenter can point a hand-held laser pointer at only one screen at a time. If the audience at the other side of the room has difficulty seeing the laser pointer dot, the presentation performance may be compromised. This paper introduces a robotic laser pointer system to solve such a problem. After calibration, a camera...
In this study, we applied reinforcement learning to actual quadrotor unmanned aerial vehicles (UAVs). It is expected that UAVs will contribute to multiple fields (e.g., rescue, sports, and entertainment). However, the autonomous control of UAVs is still a difficult problem to solve. We applied reinforcement learning to a UAV to achieve stable hovering. Q-learning, a common reinforcement learning method,...
