It is based on a green proxy object, which moves around in the acting space by way of four transparent wires. A separate unit controls four winches and is connected to an engine, which renders the virtual set. A new developed plugin registers a virtual object's position with the proxy object which imitates the virtual object's movement on stage. This will allow actors to establish important eye contact with a virtual object and feel more comfortable in a virtual set. Furthermore, interaction with the virtual object and its proxy can be realised through a markerless actor tracking system. Several possible scenarios for user application were recorded and presented to experts in the broadcast industry, who evaluated the potential of SpiderFeedback in interviews and by questionnaires.}, language = {en} } @inproceedings{FiedlerRillingBogenetal.2015, author = {Fiedler, Jannik and Rilling, Stefan and Bogen, Manfred and Herder, Jens}, title = {Multimodal interaction techniques in scientific data visualization: An analytical survey}, series = {In Proceedings of the 10th International Conference on Computer Graphics Theory and Applications (GRAPP-2015)}, booktitle = {In Proceedings of the 10th International Conference on Computer Graphics Theory and Applications (GRAPP-2015)}, editor = {Braz, Jos{\´e}}, publisher = {SCITEPRESS}, address = {s. l.}, isbn = {978-989-758-087-1}, doi = {10.5220/0005296404310437}, pages = {431 -- 437}, year = {2015}, abstract = {The interpretation process of complex data sets makes the integration of effective interaction techniques crucial.

However, it is still unclear which factors make these user interfaces superior to unimodal user interfaces. The contribution of this work is an analytical comparison of a multimodal and a unimodal user interface for a scientific visualization application.

In order to reduce the cognitive load of the learners effectively, 5Code was designed such that all 5 steps are permanently presented, accessible and executable. Thus, learners are provided with the entire programming context from presentation of the task via own notes and annotations to the code area. Learners can mark and annotate any part of the given task's text; these annotations can be edited as notes with own comments. Furthermore, the notes can be dragged into the code area, where they are shown as comments in the coding language. Any modifications in the comments are synchronized between notes and code. 5Code is implemented as a web-application.
