Abstract: Todays user interface buiders are limited to the user inteface and they ignore the semantics of the application. Direct manipulation and integration of application and interface are, in today's tools, only addressed at the level of widgets. ACE is an application framework supporting Visual Formalisms.

Abstract: Visual programming systems are supposed to simplify programming by capitalizing on innate human spatial reasoning skills. I argue that: (i) good visual programming environments should be oriented toward their application domains, and (ii) tools to build domain-oriented environments are needed because building such environments from scratch is very difficult. The demonstration illustrates how the visual programming system builder called Agentsheets addresses these issues and demonstrates several applications built using Agentsheets.

Abstract: This paper argues that grid-based spatial reasoning can significantly improve human-computer interaction. While grids constrain the user’s ability to position objects on a screen on one hand, they greatly increase the transparency of functional relationships among these objects on the other hand. A system called Agentsheets employes the notion of agents organized in a grid. The spatial relationships between agents are used to capture design properties independent of domain and programming language. Two types of spatial relations are distinguished called strict-spatial relations and pseudo-spatial relations. This paper gives a short introduction to Agentsheets, explains how Agentsheets address problems of construction kits, sketches sample applications, and evaluates the contribution of grid-based spatial reasoning to human-computer interaction.
