Purpose – The paper aims to present interactive simulation with haptic feedback as a valid method for solving complex assembly problems in the context of industrial product development. Its purpose is to clarify the position of interactive simulation with respect to other methods, and to emphasize its specific value for design engineers. Design/methodology/approach – The paper describes the cha...

Modern information technologies increase the range of feedback strategies that can be implemented in computer based learning environments; however, the design and implementation of feedback strategies are very complex tasks that are often based more on intuition than on psychologically sound design principles. The purpose of this chapter is to present theoretically and empirically based guideli...

Feedback is an important component of interactive learning software. A conclusion from cognitive learning theory is that good software must give the learner more information about what he did. Following the ideas of constructivist learning theory the user should be in control of both the time and the level of feedback he receives. At the same time the feedback system must identify and review di...

We consider interactive communication performed over two simple types of noisy channels: binary error channels with noiseless feedback and binary erasure channels. In both cases, the noise model is adversarial. Assuming at most εfraction of the bits can be corrupted, we show coding schemes that simulate any alternating interactive protocol with rate 1 − Θ(H(ε)). All our simulations are simple, ...

In our TREC-5 ad-hoc experiment, we tested two relevance feedback models, an adaptive linear model and a probabilistic model, using massive feedback query expansion (Sumner & Shaw, 1997). For our TREC-6 interactive experiment, we developed an interactive retrieval system called IRIS (Information Retrieval Interactive System), which implemented modified versions of the feedback models with a thr...

One of the difficulties in teaching basic molecular biology concepts to the students with little biological background is the lack of hands-on exercises that combines the challenges of the concepts with visualization and immediate feedback. BIOPS Interactive is a web-based interactive learning environment for molecular biology that complements traditional lecture and text coursework. It include...

We develop a novel interactive segmentation and 3-D visualization system for cone-beam computedtomography (CBCT) data in a personal computer environment. Its design includes both a new user interface to ease the interactive manual segmentation of the volume rendered and artifact-suppressing algorithms to improve the quality of CBCT images. Four pipelines of noise removal were carried out by app...
