In this article we present and discuss a prototype for a mobile application to manage the drug regime of a wearer. From a survey of requirements, along with doctors, pharmacists and users of the national health system, we designed a prototype of FARMACIL application, for which we have obtained very promising results in acceptance testing, from a universe of people in various age groups.
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...
Augmented Reality (AR) enhances real-world view with additional virtual information. This technique can be applied to a variety of industrial applications. It can be used to localize equipment in an industrial plant, to identify a dedicated device or to show its configuration. In addition, AR can be used in remote service situations, where remote experts are guiding local field workers in maintenance...
The goal of our work is to create highly realistic graphics for Augmented Reality on mobile phones. One of the greatest challenges for this is to provide realistic lighting of the virtual objects that matches the real world lighting. This becomes even more difficult with the limited capabilities of mobile phone GPUs. Our approach differs in the following important aspects compared to previous attempts:...
This paper explores how mobile devices can provide useful multimodal feedback during interactions with NFC-tagged objects. We exemplify our approach with a mobile shopping assistant that uses haptic-visual and audio-haptic feedback to inform diabetics about the agreeability of tagged grocery products. A preliminary laboratory study shows a preference for haptic-visual feedback which is regarded as...
BlindGuide is a caller system for mobile phone devices designed to provide sightless access to the blind people. Blind people can enter any phone number and also can search any name from contact list to make call to other person. Users interact to the system using five physical keys present in phone keypad. We provide an audio guideline to use BlindGuide and an auditory feedback against each unit...
With the increase in popularity of mobile technology, users can access location-aware information from virtually anywhere. Using assistive technologies, this allows people with disabilities to live more independently than ever before. For example, as people with visual impairments can not usually read the timetables posted at bus stops, a mobile application can leverage GPS and public transit information...
We designed an interactive digital signage (IDS) system for use in advertising. The system is characterized by visual content (images, videos, and texts) provision on a large display for interacting with mobile phones. Its principal feature is that it enables users to easily perform tasks such as making restaurant reservations and televoting. It is also applicable to fixed mobile convergence (FMC)...
We have developed a multimodal interface; Framy to effectively display large 2-dimenetional data sets such as geographical data on a mobile interface. We have now extended this to be used by visually-impaired users. A pilot study that we conducted, and the interviews with a group of potential stakeholders, helped us to detect some critical problems with the current interface, derive further requirements...
Current advancements in web technologies are enabling to develop new features of interactive systems that rely on cloud infrastructure and services. In this paper, we present our efforts related to the development of three prototypes of a web-based visualization tool that use Google Cloud Services to process and visualize geo-temporal data. The domain in which these efforts are taking place is in...
In this paper, we propose motion and tilt as an input technique for Weight-Shifting Mobiles, a recently proposed mobile interactive system that employs a moving center of gravity as an output channel. We present a prototype that combines weight actuation with accelerometer input. We discuss how motion- and tilt-based applications in current mobile devices can be enhanced through weight actuation,...
Screen transition and animation has long been used to represent information, cues and to enhance visual appeals on screen presentation. However, the use of screen transition and animation on mobile application has been restricted in the past due to mobile device constraints. Recent development of more powerful devices has sparked interest in implementing animation technique to improve usability on...
Picadomo combines content-based image retrieval and faceted search on mobile devices. It is designed for finding images with desired visual properties, tags or other known metadata. Due to the limitations of mobile devices such as small screen sizes and low processing power, we had to carefully select the features that come in use (dominant color, GPS data, tags, etc.). With Picadomo the user can...
The problem of private location-based queries has been intensively researched in recent years. Several location protection algorithms exist, most of which use some form of location cloaking. However, existing work focuses on the analysis of privacy and performance, and less on the user's perspective on location privacy. We developed a prototype of the PROBE system with an emphasis on visualization...
Visualization on mobile devices not only means accommodating to a small screen space, but also widely different aspect ratios. Improving on the MagicEyeView algorithm, this paper presents a visualization technique that is better suited to screens with skewed aspects ratios. The presented approach is a focus+context visualization effort which employs distortion of coordinate scales and a "fisheye"...
In next generation of smart computing environment, myriads of networked resources are pervasive and embedded into everyday consumer products and appliances. Still, most controller systems provide separate control user interfaces for different uses when users inevitably face an increased number of interfaces for control and interaction tasks in such environment. To simplify burdens of user and reduce...
As ubiquitous personal communication devices, SMS enabled mobile phones have affordances to extend communication beyond the user's personal social network and into the realm of public discourse. The author developed an interaction project, entitled Write a Story, One Line at a Time, in which users collaborated to write an SMS narrative to be displayed in a public space. The system includes visuals,...
