Research On Interactin Design And Assessment Of3D Visualization System Based On Multi-touch Platform

Importing touch technology, especially multi-touch into the3D visualization system, playtouch interaction natural and efficient to solve the existing problems of the interaction of3Dvisualization system, which greatly increase the visualization system operability and availabilityof great significance for the interaction and the overall design of the visualization system.Departure from the technical characteristics of the multi-touch technology, induction, userfactors as well as hardware and software factors in the3D visualization system design andimplementation of the3D visualization system, multi-touch human-computer interaction, andsummarize based on Visualization System for multi-touch interaction design principles, and onthis basis, summarized and the establishment of the quantitative evaluation of the touchinteraction guidance system, the main contents include:1．3D visualization system of multi-touch interactive gesture design. Summarize analysis ofthe basic functions and tasks of the3D visualization system, and on this basis, summarize thesimilarities and differences in the analysis of the mainstream platform for multi-touch gestures,design multi-touch interactive gestures of3D visualization system.2．Summary comparison of different touch platform driver development kit, look for similarthings in common, and on this basis to design the common touch platform development interfaceand touch platform gesture recognition model.3．A summary of the touch interaction design principles-based visualization system.Analyzed based on the multi-touch features, as well as the similarities and differences with otherinteractions, users and software factors, and in accordance with the existing principle of interfacedesign principles, summed up the multi-touch interface design principles and experimentalverification, to provide a reference for subsequent multi-touch interaction design.4．3D visualization system to multi-touch the interactive evaluation system. Summary of theanalysis based on user needs and the applications of multi-touch interactive design process,design principles summarized, evaluation of the target tree to refine the evaluation of the overallobjectives, to establish the evaluation system, including three goals and evaluation of sub-goalsone by one evaluation the resolve of the task and give a score reference, and finally to developthe evaluation method of calculating the weighting coefficients formula to determine theweighting coefficient of each evaluation to determine the evaluation system for interactivedesign pros and cons of assessment to provide quantitative reference.5．Implementation and evaluation of3D visualization system. First, based on designprinciples and implementation techniques of visualization system, the3D visualization system interaction module design and implementation, followed by three commercial visualizationsystem interaction evaluation test on the establishment of the touch interaction to quantifyevaluation system to verify the effectiveness. Make use of evaluation system on the design ofvisualization system interaction module to comparative evaluation summary of the amendmentsof the interactive modules and on this basis.
