A visual, open-ended approach to prototyping ubiquitous computing applications

Abstract

Abstract-By nature, ubiquitous computing applications are intimately intertwined with users' everyday life. This situation is challenging because it requires to make the development of applications accessible to end-users. Furthermore, ubiquitous computing consists of a variety of areas, including home automation and assisted living, raising a need for an open-ended approach.We present Pantagruel, a visual programming language that is end-user oriented.Our approach is open-ended in that Pantagruel integrates a language to describe a ubiquitous computing environment. Such description takes the form of a taxonomy, defining the entities relevant to a given ubiquitous computing area. This description serves as a parameter to a sensorcontroller-actuator development paradigm. The orchestration of area-specific entities is supported by high-level constructs, customized with respect to taxonomical information.We have implemented a visual environment to prototyping ubiquitous computing applications. Furthermore, we have developed a compiler for Pantagruel that targets a domain-specific middleware. Our environment leverages a 2D renderer to enable the simulation and of applications. We successfully simulated a range of applications in various ubiquitous computing areas, such as home automation, assisted living and building management.

Allowing end-users to participate within model-driven development approaches

“…Pantagruel integrates an end-user oriented language to describe a pervasive environment following a sensor-controller-actuator development paradigm. This paradigm improves the usability of non-SP participants according to the studies assessed in [8]. Fig.…”

“…For the smart home domain example, we selected Pantagruel [8] as the DSVL. Pantagruel integrates an end-user oriented language to describe a pervasive environment following a sensor-controller-actuator development paradigm.…”

Denotational Semantics of A User-Oriented, Domain-Specific Language

“…An interpreter for Pantagruel has been developed in OCaml; it is a straightforward mapping of the formal definition. An implementation of a compiler towards a Java platform has also been developed based on the semantics, and was used for a demonstration of Pantagruel at a conference [9].…”

Automated Decisions in Aware Cricket Ground: A Proposal

“…It has two report modes also, one for real time report displaying each player's actual location in the field and the other to present reports with statistics of the player. Zoe Drey and Charles Consel [1]- [8] have presented a visual programming language called Pantagruel which is end-user oriented. Their approach is open ended in that Pantagruel integrates a language to describe a ubiquitous computing environment.…”

“…The stored data can be used for future analysis by the players and team management to improve their game, and overcome their weaknesses. It also finds out the weakness/strengths of other players [1]- [8]. The proposed system had 4-layers as shown in above figure.…”
