This showpiece will present iSnap, an extension of the block-based, novice programming environment Snap!, which supports struggling students by providing on-demand hints and feedback that help them complete programming assignments. iSnap extends the existing syntactic scaffolding offered by block-based programming to additionally support the implementation of programming tasks. Research on iSnap has...
In this paper, we introduce a digital edition of the Altan Tobchi, a Mongolian historical manuscript written in traditional Mongolian script. The Text Encoding Initiative guidelines were adopted to encode the named entities, commentaries, transcriptions, and interpretations of ancient Mongolian words. Named entities such as personal names and place names were extracted from digitized text by employing...
More and more people watch TV with a second device in the nearby. They use it for many different reasons: to play, to search for something, to interact with other people, etc. As a result, their visual attention is often turned to the second screen, especially during commercials. This scenario scares broadcasters, as they fear losing the advertisers' investment. Therefore, it is necessary to improve...
A novel and effective framework for the enhancement of low lighting images is proposed in this paper. The novel framework presents an optimized de-haze algorithm on inverted images to enhance the low-dynamic-range images which optimizes the complicated process of computing the parameters A and t(x). The improved gamma correction is used to enhance the image contrast for providing better visual performance...
A Kinect-based feedback system is developed for static balance ability training in this study. It includes three parts: (1) a series of demonstrations of training movements, (2) evaluation of user's gesture, and (3) real time feedback. We tested the feasibility of our feedback system to improve static balance ability with twelve participants. The participants learned and performed three movements...
Real-time video delivery in Vehicle-to-Infrastructure (V2I) scenario enables a variety of multimedia vehicular services. We conduct experiments with Dedicated Short Range Communications (DSRC) transceivers located in the mutual proximity and exchanging Skype video calls traffic. We demonstrate that the lack of coordination between the users both at the application as well as Medium Access Control...
Understanding complex behavior patterns in response to triggered forward collision warning system benefits localized user experience design, especially in safety critical scenarios from a cross-regional perspective. This paper studies driver response behavior patterns towards two alarm timings, in car-following scenarios with different traffic density. Data from 32 participants in China and 30 participants...
As computing technology advances, computers are being used to orchestrate and advance wide spectrums of commercial and personal life, an element even more significant as we immerse ourselves into the era of big data, leading to an economy heavily reliant on data mining and precise, meaningful visualizations. However, accuracy of information visualization techniques is heavily dependent on the knowledge...
Recognition of complex language objects is a proposition for human-like perception of the surrounding world by machines. The crucial complication is a high complexity of relationships that may arise in the recognition of these objects. This implies existence of a high variety of approaches for perceived image objects recognition. One of the approaches, to which also this paper is devoted, is based...
Storyline visualization, as a process of illustrating data that has a course of events via a visual medium, has been used in the area of film making for a very long time. Not so long ago, it has moved from the paper version to the digital word allowing for a wider usage. In this paper we propose its usage as a teaching tool in the area of literature reading for the Croatian class (primary language)...
The paper introduces a visual programming language and corresponding web- and cloud-based development environment called NetsBlox. NetsBlox is an extension of Snap! and it builds upon its visual formalism as well as its open source code base. NetsBlox adds distributed programming capabilities to Snap! by introducing two simple abstractions: messages and NetsBlox services. Messages containing data...
Visual programming languages (VPLs) are becoming more popular and making the transition from the informal to conventional educational settings. One of the important features of VPL is that novices are not required to remember a list of commands or complex syntax since everything they need is just there in the environment. The objective of introductory computer programming courses at the university...
Content-based image retrieval is a technology that is used to identify similar images based on their visual content. Relevant images are found by employing methods that rank images and show the top-ranked images. One important query pertaining to image retrieval methods is regarding as to how to rank the results. This paper proposes a new method based on an unsupervised Hopfield neural network that...
Visual FoxPro software is used to design and develop Li brocade pattern information management system, in order to complete operations of query, add, delete and modify, etc. to Li brocade pattern information display. The database and data table need to be establish while designing each software modules. Different tables in a database are considered as the data source in each form, and the controls...
Memorizing and recollecting the contents of long text that has been read is a real challenge. Carrying out research, organizing and associating research ideas are equally challenging. The well-known saying that “A picture is worth a thousand words” is utilized in this teaching and learning process to empower research-minded practice among students. To accomplish this task, the concept of mind mapping...
We describe a collaborative software engineering course between sighted college students and high school students with visual impairments. We designed the course as a mentorship experience, in which one college student mentor is connected to one high school student mentee. Each pair of students is responsible for a programming project. The students must learn to communicate programming concepts and...
This paper presents preliminary results for motion behavior analysis of Madagascar hissing cockroach biobots subject to stochastic and periodic neurostimulation pulses corresponding to randomly applied right and left turn, and move forward commands. We present our experimental setup and propose an unguided search strategy based stimulation profile designed for exploration of unknown environments....
Creating immersive and aesthetic auditory spaces in virtual reality primarily focuses on enhancing the quality of an interactive experience for the user by utilizing a sophisticated combination of advanced immersive audio techniques and tools. While emerging Virtual Reality (VR) audio design and development best practices are documented herein, specific real world examples are also presented which...
For successful teleoperation, an operator must be able to accurately inscribe the desired movement to the manipulandum. The goal of manipulating an image display for teleoperation is to perform visual transformations that minimize mental fatigue, performance time, and enhances the compatibility between the operator and the teleoperated system for successful task completion. A concept based on multiple...
Virtual Reality technology has a promising future in the area of living space because of its capacity for deconstructing data of space and visualization. The article is mainly about the brand new ways of space designing and the application of intelligent home system based on virtual reality technologies. It describes the revolution this technology will bring in constructing a humanized, scientific,...
