Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as rigid objects, fluids, cloths and rag-doll characters, commercial applications still resort to kinematics-based approaches for the animation of actively controlled characters. However, in recent years, research on inte...

Speech animation synthesis is still a challenging topic in the field of computer graphics. Despite many challenges, representing detailed appearance of inner mouth such as nipping tongue’s tip with teeth and tongue’s back hasn’t been achieved in the resulting animation. To solve this problem, we propose a method of data-driven speech animation synthesis especially when focusing on the inside of...

ÐIn this paper, we consider accelerated rendering of high quality walkthrough animation sequences along predefined paths. To improve rendering performance, we use a combination of a hybrid ray tracing and Image-Based Rendering (IBR) technique and a novel perception-based antialiasing technique. In our rendering solution, we derive as many pixels as possible using inexpensive IBR techniques with...

Synchronization of speech, facial expressions and body gestures is one of the most critical problems in realistic avatar animation in virtual environments. In this paper, we address this problem by proposing a new high-level animation language to describe avatar animation. The Avatar Markup Language (AML), based on XML, encapsulates the Text to Speech, Facial Animation and Body Animation in a u...

This study examined the impact of an automated reading strategy trainer called the Interactive Strategy Trainer for Active Reading and Thinking (iSTART) for improving students’ reading comprehension of a science text. iSTART is an interactive trainer that utilizes animated agents to provide reading strategy instruction. The program contains both vicarious and interactive modules that provide ad...

l2 research has shown that instruction in l2 pragmatics is necessary. the current study evaluated the impact of explicit instruction on efl learner's awareness and production of three speech acts of request, apology, and complaint. it also probed whether learners’ language proficiency plays any role in incorporating pragmatic instruction into the l2 classroom. iranian undergraduate student...

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...

abstractthe present study explores the impact of corpus-based collocation instruction on intermediate iranian efl learners' writing ability. for this study, 84 iranian learners, studying english as a foreign language in bayan institute, iran, were selected and were randomly divided into two groups, experimental and control. conventional methods of writing instruction were taught to the control ...
