Self-generated drawings for supporting comprehension of a complex animation

The perceptual and cognitive processing demands involved in comprehending complex animations can pose considerable challenges to learners. There is a tendency for learners to extract information that is highly perceptually salient but neglect less conspicuous information of crucial relevance to the building of a quality mental model. This study investigated the effectiveness of self-generated drawing for learning from an animation illustrating a scientific phenomenon, the so-called “Newton’s Cradle.” Participants were 199 students in grade seven, randomly assigned to three experimental conditions: self-generated drawing, traced/copied drawing, and no drawing. All participants were asked to produce an explanation of the animation for both immediate and delayed posttests. The results revealed the superiority of self-generated drawing in supporting animation comprehension at both testing times compared to the other two conditions, which did not differ from each other. In addition, comprehension of the animation was related to the quality of self-generated drawings. Specifically, the depiction of information characterized by low perceptual salience but high conceptual relevance to the phenomenon predicted comprehension and retention over time.     

Multimedia category preferences of working engineers

Many have argued for the importance of continuing engineering education (CEE), but relatively few recommendations were found in the literature for how to use multimedia technologies to deliver it most effectively. The study reported here addressed this gap by investigating the multimedia category preferences of working engineers. Four categories of multimedia, with two types in each category, were studied: verbal (text and narration), static graphics (drawing and photograph), dynamic non-interactive graphics (animation and video), and dynamic interactive graphics (simulated virtual reality (VR) and photo-real VR). The results showed that working engineers strongly preferred text over narration and somewhat preferred drawing over photograph, animation over video, and simulated VR over photo-real VR. These results suggest that a variety of multimedia types should be used in the instructional design of CEE content.

Not the silver bullet: Learner-generated drawings make it difficult to understand broader spatiotemporal structures in complex animations

Because drawing is a highly successful strategy in learning from text, it has recently been investigated whether drawing can also improve learning from animation. Several theoretical and practical arguments, however, make drawing a questionable strategy for learning from animation. In an experimental study, we investigated the effectiveness of drawing for learning from animation. One group of 26 students had to draw what they had observed in the animation. A second group of 26 students had to reflect on what they had observed in the animation. After learning, all students had to demonstrate their understanding by making use of a physical model. The students' demonstrations were assessed by means of an event unit analysis. More extensive spatiotemporal structures were significantly less recognized by students who drew than by students who reflected. The results suggest that drawing might not be an adequate strategy for learning from visuospatially and spatiotemporally complex animations.     

Real-Time Arm Animation with Natural Collision Avoidance

A novel approach to realistic collision-free animation of the upper limb was proposed.According to the obstacle-avoidance strategy of human hand,the movement trajectory was computed by manipulability model and minimum-jerk based interpolation.In each key frame,an improved in～verse kinematics method was adopted to obtain a believable posture of the upper limb.By comparing with the real movement data obtained from the motion capture device,the resultant animation was testified to be natural.This method can be performed in interactive time,and therefore is applicable in animation edit and control of virtual humans.
