Hand gesture recognition system received great attention in the recent few years because of its manifoldness applications and the ability to interact with machine efficiently through human computer interaction. In this paper a survey of recent hand gesture recognition systems is presented. Key issues of hand gesture recognition system are presented with challenges of gesture system. Review methods of recent postures and gestures recognition system presented as well. Summary of research results of hand gesture methods, databases, and comparison between main gesture recognition phases are also given. Advantages
and drawbacks of the discussed systems are explained finally.

This paper provides an evaluation of the SingleTapBraille keyboard, designed to assist people with no or low vision in using touchscreen smartphones. This application allows blind users to input characters based on braille patterns. To assess SingleTapBraille, this study compares its performance with that of the commonly used QWERTY keyboard. We conducted an evaluation study with 7 blind participants to examine the performance of both keyboards on Android platforms. Overall, participants were able to quickly adjust to SingleTapBraille and type on touchscreen devices using their knowledge of Braille patterns within fifteen to twenty minutes of introduction to the system. The SingleTapBraille keyboard was better than the QWERTY keyboard in terms of both speed and accuracy, indicating that SingleTapBraille represents an improvement over existing alternatives in making touchscreen keyboards more accessible for blind users. Based on the evaluation results and the feedback of our participants, we discuss the strengths and weaknesses of previous keyboards that have been used by participants, as well as those of SingleTapBraille. In doing so, we consider possible design improvements for the future development of accessible keyboards for blind users.

Virtual Museum can present user experience in visualizing the real museum. This technology can give better communication and interaction with visitors. According to the preliminary study, most tourists have difficulty getting information about Muzium Negara and the website of Muzium Negara which does not provide enough information about galleries and collections before, during and after visiting the museum. In this study, heuristic evaluation was conducted with six experts in evaluating Virtual Muzium Negara prototyping. Several comments from experts for improving the prototyping obtained. The findings show the experts’ comments are helpful in improving the prototype and the result of the Content Validity Index is acceptable. Hence, it is hoped that the Virtual Muzium Negara prototyping can give several information to tourist and this can encourage them to visit Muzium Negara.

Everything that we do as researchers is based on what we write. Especially for graduate students and young researchers, it is hard to turn a research project into a successful CHI publication. This struggle continues for postdocs and young professors trying to provide excellent reviews for the CHI community that pinpoint flaws and improvements in research papers. This course provides hands-on advice on how to write papers with clarity , substance, and style and how to structure reviews that are helpful and focused on enhancing someone's research. It is structured into two 80-minute units with a focus on writing and reviewing respectively.

We present a review of research related to the usability testing of mobile applications including participants with Down syndrome. The purpose is to identify good usability testing practices and possible guidelines for this process when participants are people with this cognitive disability. These practices and guidelines should account for their specific impairments. We applied document analysis techniques to searches of scientific databases. The results were filtered considering how well they matched the research topic. We processed and reported the classified and summarized results. The main findings of this literature review is that mobile applications usability testing including people with Down syndrome is an issue that has not be comprehensively investigated. While there is some related research, this is incomplete, and there is no single proposal that takes on board all the issues that could be taken into account. Consequently, we propose to develop guidelines on the usability testing process involving participants with Down syndrome.

The usability testing of mobile applications involving persons with Down syndrome is an issue that has not be comprehensively investigated and there is no single proposal that takes on board all the issues that could be taken into account[1]. This study aims to propose a practical guidëUSATESTDOWN¨to measure and evaluate the usability of mobile applications focusing on Down syndrome users and their primary limitations. The study starts with an analysis of existing methodologies and tools to evaluate usability and integrates concepts related to inspection and inquiry methods into a proposal. The proposal includes the opinions of experts and representative users; their limitations, the applicability during the development process and the accessibility. This guide is based on the literature review and the author's experience in several workshops where persons with Down syndrome used mobile devices.

Although there is a large body of literature on research into colour in human-computer interaction, the overwhelming majority of the literature emphasises the cognition by computer users. However, colour is also important in this interaction when users manually type data into a computer. This paper investigates the effect of colour combinations on manual data typing. To this end, three experiments were conducted where the subjects were requested to read several texts with different colour combinations and re-type them in the same screen. Typing accuracy and speed is measured as the dependent variable across different colour combinations. Three experiments were conducted as such. In the first experiment, display and input windows were close to each other and in the second one they were located in the opposite ends of the screen. The third experiment was a subset of the first one with reversed foreground and background colours. It was found that different colour combinations had varying effects on data typing performance and proximity of the display and input windows was not a significant factor for typing accuracy in a 17-inch screen. The effect of reversing the foreground and background colours was inconclusive with the colour combinations used.
