- PublicationPedagogy Enhancement with Mobile Learning: A Case Study of the University of the Thai Chamber of CommerceThis paper shares a success story of the planning, development, and evaluation of a hybrid learning pedagogy, called iHybrid, adopted at the University of the Thai Chamber of Commerce (UTCC), one of leading private universities in Thailand. The university deployed a cloud-based learning platform, which has accommodated the 21st century learning concept that everyone can learn anything, anytime, anywhere via mobile devices. Since 2011, all new students were given an iPad and are able to access three online resource pools including ELearning System, Virtual Learning Environment (Moodle) and iTunes U. Currently, 410 lecturers (80%) and more than 10,000 students (60%) have joined the iHybrid program. Drawing on both CTE perspectives and student feedback, the paper describes successful transformation process, proposes an iHybrid framework and a learning model, reports adoption results, assimilates success factors, discusses some issues, and assesses the implications for future offerings of all courses through the iHybrid mode.

; School of Science and TechnologyResult of my literature review shows the important characteristics of three distinct modalities and the factors influencing interaction in a ubiquitous computing context. Research aim is to develop the principles for the design of multimodal interactive systems in a ubiquitous environment.14 - PublicationA direct experimental comparison of back array and waist-belt tactile interfaces for indicating direction(Workshop on Multimodal Location Based Techniques for Extreme Navigation at Pervasive, 2010-05-17)
; ; School of Science and TechnologyResearch has shown that two popular types of wearable tactile displays, a back array and a waist belt, have successfully aided pedestrian navigation. Each type has its proponents and each has been reported as successful in experimental trials. However, it is not clear which of the two is more effective for tactile-based navigation. In this short paper, we summarise the results from a direct experimental comparison of the back array and waist belt approaches. Results indicated that the tactile belt allowed participants to perform significantly faster and more accurately than the tactile back array.19 - PublicationA comparison of two wearable tactile interfaces with a complementary display in two orientationsResearch has shown that two popular forms of wearable tactile displays, a back array and a waist belt, can aid pedestrian navigation by indicating direction. Each type has its proponents and each has been reported as successful in experimental trials, however, no direct experimental comparisons of the two approaches have been reported. We have therefore conducted a series of experiments directly comparing them on a range of measures. In this paper, we present results from a study in which we used a directional line drawing task to compare user performance with these two popular forms of wearable tactile display. We also investigated whether user performance was affected by a match between the plane of the tactile interface and the plane in which the users drew the perceived directions. Finally, we investigated the effect of adding a complementary visual display. The touch screen display on which participants drew the perceived directions presented either a blank display or a visual display of a map indicating eight directions from a central roundabout, corresponding to the eight directions indicated by the tactile stimuli. We found that participants performed significantly faster and more accurately with the belt than with the array whether they had a vertical screen or a horizontal screen. We found no difference in performance with the map display compared to the blank display.

Landmark information may provide a useful complement to directional information for navigation, however, there has been no reported use of landmark information in tactile navigation displays. We report a study that compared two tactile display techniques for landmark representation using one or two actuators respectively. The single-actuator technique generated different vibration patterns on a single actuator to represent different landmarks. The dual-actuator technique generated a single vibration pattern using two simultaneous actuators and different pairs of actuators around the body represented different landmarks. We compared the two techniques on four measures: distinguishability, learnability, short term memorability and user preference. Results showed that users performed equally well when either technique was used to represent landmarks alone. However, when landmark representations were presented together with directional signals, performance with the single-actuator technique was significantly reduced while performance with the dual-actuator technique remained unchanged.
