Promoting awareness of depression with a mobile application: A usability study and evaluation

This paper reports selected results from a study designed to understand the potential and limitations of a mobile application in promoting health awareness of depression to patients, their families and others. The mobile application was developed with a user-centered approach, which emphasized user preferences and opinions throughout an iterative process of development. It comprised medical information about depression, and causes, symptoms and methods of treatment. We conducted several design and evaluation sessions with a group of users (patients, their family, doctors, nurses and general users). Our findings demonstrate that the mobile medical application has the potential to improve and increase awareness among patients and their family members.

Calibration on Co-located Ad-Hoc Multi Mobile System

This paper presents findings about connectivity issues when using clock wise swipe gesture of mobiTop system. The mobiTop system is a multi-mobile system that allows users to come together at any location and perform collaborative tasks and information sharing by extending their mobile devices. This study investigates the user experience issues when multiple users calibrate and align multiple mobile devices using the mobiTop system. From the study, users took an average of 5.47 minutes to initiate connections between multiple devices. The finding shows that the existing calibration setting is too complicated for the users despite the step-by-step tutorial provided by the system. The findings also show that although only one user is needed to initiate to connectivity, most of the users tend to contribute towards simultaneous connectivity input leading to system disorientation. Following this, several connectivity methods explored that can be employed by the mobiTop system to minimize connectivity time and promote a seamless integration between the users and the system.

MobiTop: Interactivity Issues in a Multi-Mobile System

Mobile devices are increasingly becoming an important part of technology. As the demand for handling information grows, so does the need for collaboration in integrating and managing multiple forms of information. With its small screen, it is relatively uncomfortable for a group of people to perform task collaboratively. This paper presents MobiTop - a multi-mobile system that integrates mobile devices that works seamlessly together -- promoting an extended screen size for the mobile devices to support collaboration. However, interactivity issues such as bezels and screen orientation are found to restrict users from performing collaborative tasks favourably. This paper discusses the interactivity issues pertaining multi-mobile systems and offers guidelines for designers.

Evaluation of preschool children's fantasy play in the tabletop environment

This paper presents the experience and findings of a user study investigating preschool childrens fantasy play. Ten same-sex dyads of children (aged 3 and 4) were observed playing with the physical farm toys and the virtual farm set implementation on a Mitsubishi DT multi-touch interactive tabletop. Both qualitative and quantitative data were performed for data collection. Findings showed that high evidence of fantasy play bouts performed by the participants during the physical and the virtual Session 2. This paper also reports the similarities and differences between physical and virtual play environments.

Supporting social pretend play with a virtual toy

This paper presents selected results from a study designed to explore childrens social pretend play in a virtual setting. Fourteen children (aged 5--8) played in pairs with a mobile-based game implemented on an Apple iPad. Interviews and video transcriptions were used to assess three types of social pretend play, which included solitary, simple and associative. Our findings revealed the ways children engaged with the virtual toy and demonstrate social pretend play. We discuss the implications of these findings and provide a series of design implications for designers and researchers.

A lo-fi prototype testing with preschoolers to design organic user interfaces

This workshop aims to understand how children interact with interface using deformation-based gestures by observing them interacting with paper prototype. The earliest form of communication is through gestures and they help children to learn better. Current technology lacks natural form as it is a flat surface and does not allow deformation-based gestures. Therefore, we want to gain user-defined gestures that would serve as guidelines to designers who are trying to design and implement future deformable interface. A paper prototype is suggested due to its flexibility and not confined by current technical limitations.

USING HEURISTIC EVALUATION TO IMPROVE THE USABILITY OF ELECTRONIC MEDICAL RECORD (EMR) MOBILE INTERFACE OF THE CARDIOTHORACIC SURGERY AND ANESTHESIA SYSTEM (CSAS)

This paper presents initial work on mobile user-interface for electronic medical record for cardio experts. The current problem exits when the existing system is left unused by the users, in our case the cardio surgeons due to bad user interface design which involve a heavy cognitive loads and navigation problems. Medical records contain treatment history and relevant experiences related to the patient care. In order to avoid paper based medical record (PMR) drawbacks, most industrialized nations have implemented electronic medical record (EMR). This research aims to evaluate the existing CSAS system usability using heuristic evaluation and then develop an EMR system that overcomes the interface usability problems by designing an effective user interface that is acceptable to healthcare professionals with tablets as the device. Hence, proposing a new user interface prototype taking into account the findings from the evaluation process.
