How can animation be used to promote learner understanding of scientific and mathematical explanations? In this review, we examine the role of animation in multimedia learning (including multimedia instructional messages and microworld games), present a cognitive theory of multimedia learning, and summarize our program of research, which has yielded seven principles for the use of animation in ...

We present in this paper a platform which integrates the different animation models: descriptive, generative and behavioural models. The integration of these models in the same platform permits to offer to each dynamic entity a more realistic and a richer environment, and thereby to increase possible interactions between an actor and its environment. Therefore we describe the unification and th...

When compared to gaze, animation of the eyelids has been largely overlooked in the computer graphics literature. Eyelid movement plays an important part both in conveying accurate gaze direction and in improving the visual appearance of virtual characters. Eyelids have two major motion components: lid saccades that follow the vertical rotation the eyes, and blinking. Derived from literature in ...

This paper examines capacity limits in mental animation of static diagrams of mechanical systems and interprets these limits within current theories of working memory. I review empirical studies of mental animation that examined (1) the relation of spatial ability to mental animation (2) the effects of working memory loads on mental animation, (3) use of external memory in mental animation and ...

This study examined the effects of computer animation instructional package on secondary school students’ achievement in practical biology Ilorin, Nigeria. The adopted a pre-test, post-test, control group, non-randomised and nonequivalent quasi-experimental design, with 2x2x3 factorial design. Two intact classes from two schools were purposively sampled. instruments used Biology Practical Achie...

Research results from a previous study show that animation as non-primary information significantly reduces information-seeking performance in a web-based environment (Zhang 2000). This study continues to explore the impact of animation timing and location on visual search tasks. The results indicate that (1) animation that appears during the middle or toward the end of an information-seeking t...
