the relative eye size, types of visual cell and mosaic, and the existence of retinal tapetum in the eyes of the spotted barb puntius binotatus were determined to gain baseline information on its visual capability. the p. binotatus acquired relatively larger eye size than the other similar sized freshwater fish species with its retina being contained both cone and rod visual cells (cone ellipsoi...

Much of the guidance provided to designers of visual displays is highly simplified because of historical limitations of visual display hardware and software. Vast improvements have been made in processors, communication channel bandwidth, and display screen performance over the past 10 years; and the pace of these visual system improvements is accelerating. It is now time to undertake a critica...

A novel scheme for visual communication by means of mobile devices with limited colour display capability is proposed. A colour quantization technique is first proposed based on the perception of human visual system on skin colour. An efficient coding scheme is then developed to compress colour quantised video at very low bit rate.

Experiences from several European projects which are focusing on issues like serious gaming (project PRIME), e-learning activities (project SMART-UP), and assessment methods (project COIN) serve as case studies to learn more about the integration of these methods to better support skill assessment and development. The purpose of this paper is to present an integrated concept supporting skill de...
