Smartphones have become essential to modern day living, almost like a sixth sense to the human being. Touchscreen display for user input is the norm in Smartphones. However, this is a huge inconvenience for the visually challenged users. The available solutions to this problem are quite expensive and therefore not affordable to all sections of this disadvantaged community. We have successfully developed...
Kinesthetic information is beneficial in detecting, recognizing, and interpreting haptic objects in virtual space. Unfortunately, kinesthetic feedback requires linkage-based high-powered multi-dimensional manipulators, such as exoskeletons or robotic arms, which are currently not possible to integrate with mobile devices. To overcome this challenge, we describe a novel system that is able to apply...
Approximately more than eight hundred (800) First Year Students at the University of Namibia in 2010 and 2011 were enrolled in Mathematics class against a few teaching staff. As such this resulted in a challenge to individual students' attention, which yielded low passing rate. To improve that, the students in their spare time tried to make use of computer services to revise and practice their Mathematics...
Physical activities play important role in having better health. However, due to the nature of our jobs, most of us have developed sedentary habits and it is very seldom that we find dedicated time for exercise or other physical activities. Sedentary behavior has been identified as an important factor in preventing good health and there is a need to push adults to carry out physical activities regularly,...
Information Technology, when implemented in healthcare, has the potential to radically improve the quality and efficiency of services being made available to patients. With the advent of mobile computing and wireless sensor networks, data acquisition and processing has become much faster and less expensive. Since there is an increase in possible software attacks on privacy and safety of health applications,...
This paper presents the results of the first phase in a multi-phase study developing an educational fitness application on mobile devices to help combat the growing levels of obesity among youth age 11 to 17. This first phase studies demographic differences across age and gender with regards to physical activities, computer games and mobile technology usage in order to develop an adaptive mobile fitness...
We developed new interactive display system called the palm display. Our prototype system shows the image of graphical user interface on the palm and allows the user to have interaction with it using fingertip as they manipulate a common mobile device with stylus pen. We implemented this system using image processing technology and employed common projector and a networked PTZ camera. The feature...
The paper describes a location-aware travel guide prototype that was implemented into a Nokia Symbian Series 60 phone with Location API (JSR-179) support. It contains relevant travelling information that could assist users while they are travelling or when they arrive at a particular destination. The objectives of the study were to discover user preferences towards fisheye and list style menus in...
Today's mobile devices have inherited many of the characteristics of desktop computing -- including the assumptions that the user's full attention and dexterity can be focused on the interface. Unfortunately, on-the-go users are impaired by their mobility and often find desktop-style Windows Icon Menu and Pointer (WIMP) interfaces difficult, if not impossible, to use while performing their primary...
Applications of 3 dimensional (3-D) virtual reality are now possible on current mobile phones due to the advances in mobile 3-D graphics technologies. However, the user-interface to these applications is generally still limited to the basic phone keypad which detracts from the sophisticated experience 3-D worlds can provide. In this paper we present a solution to this problem which utilizes the accelerometers...
In the past few years, many new development toolkits such as the Nebula2 and/or mobile technologies including the WiFi or mobileTV have opened up exciting learning opportunities on mobile devices. On top of it, new technologies continue to fuel the rapid growth of newly merged fields of research like the edutainment for educational entertainment. In a recent teaching development project, we have developed...
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
Semantic Web accessibility network services (SWANS) is a research project which explores ways of transforming the lives of visually impaired (VI) users. This article presents the development process of a prototype SWANS-M (Mobile) which is evolved from SWANS-W(Wireless) prototype to enhance the physical mobility of VI users using mobile devices. In this prototype we have particularly evaluated the...
A low-cost intelligent mobile phone-based wireless video surveillance solution using moving object recognition technology is proposed in this paper. The proposed solution can be applied not only to various security systems, but also to environmental surveillance. Firstly, the basic principle of moving object detecting is given. Limited by the memory consuming and computing capacity of a mobile phone,...
The use of stroke monitoring to detect patient or old people with the intent to prevent patients dead after heart operation fails. This paper presents portable patient monitoring system laboratory prototype, which provides patient electrocardiogram signals transferring via mobile extension technology with old version mobile phone in Thailand. At the human location, a wireless old version mobile phone...
Existing mobile language learning tools are Web-based and subject to connectivity disturbance that ensue in restricted use. The lack of research in the implementation of mobile language learning has ignited the motivation for this study. The proposed Multimedia Mobile Language Translation tool (MMLT), incorporating various multimedia elements such as image, video, sound and text to provide alternatives...
