Foundations of visual metaphors for schema display

Theoretical Foundations of 3D-Metaphors

Informative Art Display Metaphors

Informative Art display systems have been proposed to provide users with information considered relevant at arbitrary points of work or living engagement, originating from many different –mostly geographically dislocated– sources and presented at the periphery of human (visual) perception. Having the displays operate at the periphery of a user's attention allows other user tasks to sustain prim...

Foundations of JSON Schema

JSON – the most popular data format for sending API requests and responses – is still lacking a standardized schema or meta-data definition that allows the developers to specify the structure of JSON documents. JSON Schema is an attempt to provide a general purpose schema language for JSON, but it is still work in progress, and the formal specification has not yet been agreed upon. Why this cou...

Reasoning with visual metaphors

Research into visual reasoning up to now has focused on images that are literal depictions of their objects. I argue in this article that an important further mode of visual reasoning operates on images that depict objects metaphorically. Such images form part of the class of expressive symbols: they are found, for example, in allegorical representations in works of visual art, studied by icono...

The Joy of Visual Metaphors

With the help of an experimental artistic approach and in reference to positions from semiotics and linguistics, I investigate under which conditions visualisations are experienced as interesting and charming. After extensive research in the semiotic fundamentals of the visualisation of theoretical texts (Reichl, 2008; Reichl, 2009), this research project is concerned with what makes visualisat...
