TLDR
An object-based and a camera-based computer graphics procedure to prevent projective distortions and misalignments are introduced to provide humancentered interfaces for an efficient and coherent communication of spatial information in virtual worlds.Abstract:
Projection of three-dimensional space onto a two-dimensional surface relies on the computer graphics camera based in design on the camera obscura. Geometrical limitations of this model lead to perspective distortions in wide-angle projections. Including the camera model, our approach is to involve the human perception in order to create a realistic spatial impression by a two-dimensional image. The aim is to provide humancentered interfaces for an efficient and coherent communication of spatial information in virtual worlds to support avatar-mediated interaction with its need for correct depiction of human figures concerning proportion and orientation. To this end, we explain an object-based and introduce a camera-based computer graphics procedure to prevent projective distortions and misalignments.read more

Perspective in Two Dimensions for Computer Graphics
TL;DR: This thesis presents the framework, a computer program, developed to create the perspective of pictures based on the geometry practices of artists, which generalizes the planar geometry that solves the challenge of depicting 3D.

The standard of user-centered design and the standard definition of usability: analyzing ISO 13407 against ISO 9241-11
TL;DR: An interpretative analysis of ISO 13407 from the viewpoint of the standard definition of usability from ISO 9241-11 shows thatISO 13407 provides only partly guidance for designing usability as presumed by the definition.

The Effect of Behavioral Realism and Form Realism of Real-Time Avatar Faces on Verbal Disclosure, Nonverbal Disclosure, Emotion Recognition, and Copresence in Dyadic Interaction
TL;DR: The possibility of a hybrid realism solution that maintains high copresence without lowering self-disclosure, and the benefits of such an avatar on applications such as distance learning and therapy are discussed.
