Avery Read, James Ritchie, Theodore Lim
2016 Zenodo  
This paper reports on a pilot haptic sketch-based system to investigate its feasibility to conduct concurrent DFMA.  ...  Current tools used to carry out design for manufacture and assembly (DFMA) evaluations are time consuming to use.  ...  The centre panel contains the modelling environment where the user can create, alter and merge parts using sketch based modelling techniques.  ...

A Sketch-Based Interface for Clothing Virtual Characters

Emmanuel Turquin, Jamie Wither, Laurence Boissieux, Marie-paule Cani, John Hughes
2007 IEEE Computer Graphics and Applications  
We therefore developed a sketch-based interface that lets users quickly construct 3D virtual garments on a character model.  ...  Sketch-based interfaces seem all the more convenient because most people who design 3D objects and regularly use 3D modeling programs already use sketches and artwork extensively in early phases of the  ...  The system draws an arrowhead to indicate stroke direction and displays the model using thick lines, prior strokes using medium lines (with dots at breakpoints), and new strokes using thin lines.  ...

The Space Pen system supports annotation and drawing on (and inside) 3D VRML/Java models using a regular Web browser to exchange text and sketched annotations for review.  ...  Space Pen incorporates a 2D sketch recognizer, used to interpret pen marks made on model surfaces. Its purpose goes beyond beautifying rough sketches.  ...  Space Pen's 2D (in 3D environment) sketch recognition supports gestural commands to modify the model.  ...

A Mobile Design Environment for Building Form Generation

Mehmet Emin Bayraktar, Gülen Çağdaş
2020 Journal of Design Studio  
Current design software and modeling tools are insufficient for the architect to quickly share ideas and generate alternative suggestions for fast sketching and modeling.  ...  In order to evaluate the application, a set of images consisting of tall buildings are shown to users. Then they are asked to model a similar form of their own.  ...  Figure 10 shows the graphic depicting the location of the virtual pen in the 3D sketch and a drawing. The user draws freehand lines in the air by moving the device freely.  ...

Multimodal Interaction in a Collaborative Virtual Brainstorming Environment [chapter]

Fabian Di Fiore, Peter Vandoren, Frank Van Reeth
2004 Lecture Notes in Computer Science  
Similar to real life, we rely on the use of quick drawings or sketches as a means of communication to convey new ideas, thoughts or other metadata to other individuals.  ...  In this paper we present our work in setting up a collaborative virtual environment (CVE) framework which is built to support collaborative creative meetings for geographically dispersed participants.  ...  Furthermore, we would like to thank Jori Liesenborgs for freely putting available to us his JRTP library, and ANDROME NV for helping us to code and decode the video streams [35] .  ...

2006 ICAT-EGVE 2014 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments  
However, in the case of interactive data exploration in virtual environments it is not possible to keep a pen and pencil at hand.  ...  We describe the context-content model which allows to tie annotation content to logical objects that are part of the scene and stores specific information for the special interaction in virtual environments  ...  [Jun02] present a system that is capable of changing the virtual world by sketching, an extended interpretation of an annotation, but the system uses a Windows Icons Menu Pointer (WIMP) metaphor based  ...

B.L. Tseng, Zon-Yin Shae, Wing Ho Leung, Tsuhan Chen
2001 IEEE International Conference on Multimedia and Expo, 2001. ICME 2001.  
The system is suitable for distance learning and conferencing applications because it uses the whiteboard interface and provides a user avatar representation for any virtual environment.  ...  The shared whiteboards provide a medium for communication using handwritten inputs, as well as a desirable interface for navigation and mouse control.  ...  The setup configuration of the physical whiteboard allows the user in front of the whiteboard to (1) view the virtual environment, (2) draw sketches, (3) control the mouse on the computer screen, and (  ...

Lane Phillips, Brian Ries, Michael Kaedi, Victoria Interrante
2010 2010 IEEE Virtual Reality Conference (VR)  
Non-photorealistically rendered (NPR) immersive virtual environments (IVEs) can facilitate conceptual design in architecture by enabling preliminary design sketches to be previewed and experienced at full  ...  people a realistic avatar self-embodiment in an IVE can help them to interpret what they see through an HMD in a way that is more similar to how they would interpret a corresponding visual stimulus in  ...  On the one hand, participants could be misjudging distances when the replica environment is rendered as a line drawing because of a lack of sufficient detail in the line drawing representation.  ...

A little unreality in a realistic replica environment degrades distance estimation accuracy

Lane Phillips, Victoria Interrante
2011 2011 IEEE Virtual Reality Conference  
Our previous work found an exception to this effect: When the virtual environment was a realistic, co-located replica of the concurrently occupied real environment, users did not significantly underestimate  ...  We ran blind walking trials in a new replica IVE that combined features of the previous two IVEs. Participants significantly underestimated distances in this environment.  ...  Typically an IVE is used to display a model that was created somewhere else, but we feel there is great promise in using IVEs from the earliest steps in the design process, including sketching out initial  ...

3d Virtuality Sketching: Interactive 3d Sketching Based on Real Models in a Virtual Scene

Gerhard Schubert, Eva Artinger, Violin Yanev, Gudrun Klinker, Frank Petzold
2012 Proceedings of the 5th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)   unpublished
Sketches and working models are without doubt one of the most widely used tools in the architect's repertoire.  ...  The sketch as a design tool and its capacity to accommodate emergence represents a catalyst for stimulating not yet conceived interpretations of an idea put down on paper (Buxton 2007) .  ...  By use of a head-mounted display and sketching while being immersed in a virtual environment, it combines techniques from CAD as well as drawing programs.  ...
