Bed management is one of the most crucial tasks in a hospital. A desktop-based (PC) information technology system has been widely adopted to assist this operation. The fixed location and the limited amount of available PCs shared among staff for different routine tasks can cause delays in bed information updating and therefore delays to the bed man...
Article
Conventionally, the interaction between a user and augmented reality (AR) application is limited. Mostly, it allows virtual information browsing on the AR marker or basic manipulation such as moving and resizing of the 3D model. This study presents a rich interaction that allows users to mimic physical action such as shaking and pouring in chemistr...

This study aims to examine the feasibility of a photo-assisted electronic food diaries as an alternative tool to assess food intake among Malaysian adults. Based on the feedback that we received on our first prototype, we are currently developing our second prototype with improved recording functions. This latest prototype will be pre-tested by the end of 2016. The preliminary results of this project has been disseminated in the following seminars / conferences: Wong, J. E., Chen, Y.
