The attention function has been classified into (i) sustained attention, (ii) selective attention, (iii) controlled attention, (iv) distributed attention, and (v) capacity for attention. Ordinarily, in order to evaluate the function of attention, the digital cancellation test (D-CAT) or trail making test (TMT) are employed. However, these evaluations are in the form of paper tests, and cannot effectively...
Emotions influence our perceptions and decisions and are often felt more strongly in situations related to healthcare. Therefore, it is important to understand how both providers and patients express their emotions in face-to-face scenarios. An ontology is a way to represent domain concepts and the relationships between them in a polyarchical manner. We have created an ontological model called the...
An LED light suitable for general illumination is proposed to enhance subconscious visual responses, which are essential to our well-being. Using the silent substitution technique, a melanopsin-selective flicker was added into white light. A linear optimization algorithm suppresses perceivable fluctuations of colors of illuminated objects.
La lechería es muy importante para la economía uruguaya, por esta razón, interesa realizar investigaciones en esta área. Este trabajo comprendió la incorporación de tecnologías en sistemas lecheros para realizar estimaciones de disponibilidad de forraje. Particularmente, se estimó la disponibilidad de forraje en un potrero mediante el procesamiento de imágenes georeferenciadas de las pasturas, las...
In this paper, a robust visual tracking system with occlusion handling is proposed to track the target with real-time performance. The thermal camera, which can observe the heat originated from the target such as the human body or vehicle, can collaborate with the color camera to track the target in the cluttered environment or under occlusion. Unlike the general tracking by using the color camera...
Block-based languages are a useful scaffold for novice programmers to create syntactically correct code. However, block environments that attempt to represent feature-rich languages, such as Python or Java, face serious usability and pedagogical challenges. How can the affordances and controls of a block be exposed, without over-complicating the block's interface and obscuring its meaning to the user?...
The developed application allows to have consolidated graphic information of people with disabilities that are located in potential risk areas such as Cotopaxi Volcano. The information is indicated in real time on georeferenced maps and details the person (names, age, sex), the location of the dwelling, type of disability. This information is valuable and ends the realization of the location of these...
Instead of using HOG feature on cells or blocks, the extraction of HOG features on corner points is proposed for multiple object visual tracking system in which single or multiple moving objects could be classified. Background subtraction and extraction of corner feature are applied to track and classify the moving objects. Firstly, moving objects will be detected in the form of regions from background...
This article aims to improve the math learning process of the students in rural schools. For this purpose, a “Math-fraction” computer animation application was developed to use on the web and mobile technologies. The tool was designed using a visual approach to reinforce student's learning process acquired in classes. The tool was tested and validated by three usability user experts, thirty four students...
This paper proposes a systematic framework for applying the Physics of Notations (PoN), a theory for the design of cognitively effective visual notations. The PoN consists of nine principles, but not all principles lend themselves equally to a clear and unambiguous operationalization. As a result, many visual notations designed according to the PoN apply it in different ways. The proposed framework...
This paper presents a serious game designed for children suffering from profound intellectual and multiple disabilities (PIMD) also know as multihandicap, for their evaluation and cognitive training. The specificities of these children must be taken into account for the choice of both the game feedbacks and interfaces.
There are only a few visualisations targeting the communication of trust statements. Even though there are some advanced and scientifically founded visualisations—like, for example, the opinion triangle, the human trust interface, and T-Viz—the stars interface known from e-commerce platforms is by far the most common one. In this paper, we propose two trust visualisations based on T-Viz, which was...
Rather than being completely isolated, the various human sensory systems can influence each other, sometimes strongly. For example, the cognitive phenomenon known as “colored hearing” involves seeing colors in response to auditory stimuli. This type of special cognitive condition, in which one sensory stimulus evokes a different perception from that of the trigger, is known as “synesthesia.” Previous...
The objective of this paper is to propose an algorithm for fusion of images of two different image modalities, i.e., color visual image and its corresponding infrared (IR) image. Fusion method is based on l1 total variation minimization technique, and it combines appearance detail and thermal information for a scene using visual and IR images, respectively. Moreover, the proposed method maintains...
The tracking methods under the online multiple instance learning(MIL) framework always use single channel's information or transform the RGB image to gray image for color video tracking, which may cause the information loss of the color image. In addition, the MIL tracker only use the haar-like feature to construct the target appearance and ignore the different samples have different importance to...
Designers tend to have repetitive design strategy in the process without notices. The elements setting the interactive function is to conform the user requirement and it can improve the user experiences. Although it has many information recorded on the paper, but via the think-aloud we can find out many implicit information. Then, we can go through the sketch to understand how we define the visualize...
Trees and graphs are two data structures that are commonly used in representing different kinds of data. They also have many associated algorithms taught in different courses. It is thus beneficial to have a tool that could be used by students, teachers and programmers to visually trace how their algorithms work. The work in this paper presents, CHR-Graph, an easy-to-use platform for animating trees...
The paper introduces an approach that allows for detecting interaction with a graphical display in a rule-based declarative approach. It also introduces the possibility of connecting the interaction to a specific animation step to be performed. The two approaches were embedded into an animation system to aid in teaching algorithms.
Action recognition using depth sequences plays important role in many fields, e.g., intelligent surveillance, content-based video retrieval. Real applications require robust and accurate action recognition method. In this paper, we propose a skeleton visualization method, which efficiently encodes the spatial-temporal information of skeleton joints into a set of color images. These images are served...
This study aimed to evaluate the modifications of electroencephalographic (EEG) power spectra in overweight and obese patients. EEG was recorded while performing the Stroop Color Word Test. Stroop Color Word Test was performed and EEG activity was also monitored during the experiment. Paired t-test and independent t-test were used to show statistical difference between baseline and Stroop Color Word...
