| Summary: | 碩士 === 國立中興大學 === 資訊科學學系 === 86 === We focus on effiency and human/machine interface to improve
the current virtual environment browser.
At the effiency aspect, in order to speed up the rendering
performance.We decide to use Microsoft''s Direct3D rendering
library as developing tool.At the human/machine interface
aspect, except keep the traditional mouse/keyboard control
method, we add orally voice control method. Users can use
orally voice commands to operate the browser. Besides, if the
system can''t recognize user''s command, we also provide learning
function to customize the system with user''s idiom.
We also sloved several problems, which are followed with voice
control.Such as take apart orally voice control problem into
voice recogni tion andnatural language processing. Then use
external software to do the voice recognition job. In this way,
we can develop an orally voice control browser ina short time.
Besides, in order to eliminate the ambiguity of voice control,
weadd bounding box to 3D object and figure out the instruction
set of operating tree control by voice.
We designed and implemented a virtual environment browser to
prove our ideas above. And named it as "Echo" system. Through
the implementation of Echo system, we proved that our ideas and
concepts are practical. We improved the effiency and made the
human/machine interface more friendly of the virtual environment
browser. So, Echo system does have the contribution of improving
the virtual environment browser.
