The first paper from my PhD thesis project, titled “Understanding Learners’ General Perception Towards Learning with MOOC Classmates: an Exploratory Study”, was conditionally accepted by the ACM Learning @ Scale Conference 2015, a conference focus specifically on online learning at a massive scale, as a work-in-progress.
The study in this paper is originated from an initial discussion with the research team on this deceptively simple question: “How should we facilitate peer learning in MOOCs?” We found that although there have been a lot of studies on implementing peer features in MOOCs (think about reputation system, chat room), no study has ever inquire MOOC students about their experiences in learning with other peers in MOOCs. Hence, the motivation of this study is to understand students’ general perception towards this activity in an exploratory manner. We identified a lot of interesting and inchoate insights and we are already en route in expanding this study into a full-scale systematic investigation.
I like to thank my collaborators, Juho Kim, Toni-Jan Keith Monserrat, and my advisor Shengdong Zhao for their guidance in this project. For more information on this project, please read the paper and its official ACM page, both which will be released soon.
One of my research project, titled “ColorBless: Augmenting Visual Information for Colorblind People with Binocular Luster Effect”, was recently published in the January 2015 issue of ACM Transactions on Computer-Human Interaction (TOCHI), one of the best HCI journals in this research field.
In this work, we explored the use of binocular luster effect in augmented visualisation, focusing on its application in colourblind aids. Binocular luster effect is one of the many effects made possible with stereoscopic 3D technology (yes, the one you experienced in the cinema nowadays). During the study, we investigated the human factor issues of this effect and used that as a guideline to develop ColorBless. ColorBless is a colourblind technique that applies binocular luster effect onto one of the confusing colours in the image to make it easier and faster for colourblind users to distinguish them apart. Apart from being easier and faster, ColorBless also minimises the underlying colour change of the image, reducing the possibility of colour misinterpretation by users with normal colour vision that are not wearing 3D glasses. ColorBless is particularly useful in a meeting room scenario with both normal and colourblind users, where the colourblind users would wear 3D glasses to see the luster effect. In conclusion, we have demonstrated the HCI application of a novel effect in stereoscopic 3D in augmented visualisation. In the future, we expect the findings would benefit researchers and practitioners who are interested in using the luster effect in other exciting and innovative applications in human-computer interaction.
