Integration and Application of Animation Production Simplification in a VR Virtual Reality Teaching System
International Journal of Emerging Technologies in Learning (iJET) Vol. 11, No. 10 (Oct 27, 2016) pp. 37–41
This study designed a teaching system based on the animation model, which focuses on VR virtual reality technology and incorporates the improved computer animation modeling technique. The whole system is composed of three main parts, including the...
Single Maneuvering Target Tracking in Clutter Based on Multiple Model Algorithm with Gaussian Mixture Reduction
Journal of Applied Research and Technology Vol. 11, No. 5 (October 2013) pp. 641–652
The measurement origin uncertainty and target (dynamic or/and measurement) model uncertainty are two fundamental problems in maneuvering target tracking in clutter. The multiple hypothesis tracker (MHT) and multiple model (MM) algorithm are two well-...
Journal of Educational Technology Systems Vol. 19, No. 1 (1991) pp. 59–74
Discussion of computer-assisted learning (CAL) and the instructional functions of audio highlights the development of an interactional audio-CAL system used for second-language learning. Levels of interactivity in media are discussed, hardware that...
Generalized SSPRT for Fault Identification and Estimation of Linear Dynamic Systems Based on Multiple Model Algorithm
Journal of Applied Research and Technology Vol. 12, No. 3 (June 2014) pp. 409–421
The generalized Shiryayev sequential probability ratio test (SSPRT) is applied to linear dynamic systems for single fault isolation and estimation. The algorithm turns out to be the multiple model (MM) algorithm considering all the possible model...
Understanding User Needs for Serious Games for Teaching Children with Autism Spectrum Disorders Emotions
World Conference on Educational Media and Technology 2012 (Jun 26, 2012) pp. 1054–1063
Computer technologies, particularly games, are considered promising in assisting children with autism in learning social interactions and developing language skills, but few existing tools target a critical factor in communication, emotions. This...
Using Latent Transition Analysis to Identify Effects of an Intelligent Tutoring System on Reading Comprehension of Seventh-Grade Students
Reading and Writing: An Interdisciplinary Journal Vol. 31, No. 9 (2018) pp. 2095–2113
Latent transition analysis (LTA) was conducted on data from a recent cluster randomized controlled study of 1808 seventh-grade students' use of a web-based intelligent tutoring system (ITSS). This analysis goes beyond traditional variable-centered...
