Description :

Motivation and objectives :
The motivation of this proposal is to explore the combination of paper-based sketching with immersive sketching technologies, streamlining the different sketching modalities and hence providing designers and artists with a greater sketching flexibility. Paper-based sketching is used by many designers, particularly in the early stages of design, as it offers the flexibility and potential of drawing rough, concept sketches quickly and rapidly. However, paper is limited in its use and the designer often redraws these initial sketches using some higher-level technology to obtain functioning 3D models from the sketch. This project seeks to build upon the experiences of the Franhofer IPK and the University of Malta in paper-based sketching in order to allow a designer to use immersive sketching technologies to manipulate and combine simple 3D models obtained from paper-based sketches, thereby creating more complex objects.

Teams :
The capability of the human visual system to process, interpret and understand scenes is at the same time impressive and unassuming. That which is achieved so naturally by the human visual system has turned out to be so difficult to obtain by machine and, despite successes in the field, still remains generally elusive. The department of Systems and Control Engineering is particularly interested in the problems related to image processing for the extraction of information and knowledge from images and scenes. Problems such as image analysis and classification of remotely sensed images, recognition of white blood cells and electrophoresis gel patterns, texture segmentation and object recognition have been addressed by academics of the department. Main research in this area focuses on unsupervised texture segmentation, sketch and scribble analysis and interpretation as well as 3D data acquisition.

Recordings & Results :
Paper-based sketching is used by many designers, particularly in the early stages of design, as it offers the flexibility and potential of drawing rough, concept sketches quickly and rapidly. However, paper is limited in its use and the designer often redraws these initial sketches using some higher-level technology to obtain functioning 3D models from the sketch. The goal of this project was to explore the combination of paper-based sketching with immersive sketching technologies, streamlining the different sketching modalities and hence providing designers and artists with a greater sketching flexibility.

Conclusions :
During the project a hybrid modelling system was developed which combined 2D and immersive 3D sketching techniques. Based on this system various modelling tasks were executed to determine the most suited combination of sketching and manipulation techniques to create complex objects. First insights into the usability of the overall tool and the function allocation between 2D and immersive 3D sketching techniques were gained. The feasability of the hybrid 2D-3D modelling approach could be shown. The results of this project will be published at the 10th International Conference on Computer Graphics Theory and Applications, GRAPP 2015.
