Shape grammars (SG), which define a set of shapes, are used in applications in the field of Computational Creativity (CC). Computational Creativity can be considered an area of Artificial Intelligence (AI) that chases the goal of understanding creativity and building computational applications that emulate or support human creativity in Arts and Science. In this context, our aim is to show how SG may provide artists with applications to assist them in the creative process, not only creating solutions but also as a way of creating new ideas. Our objective is to demonstrate how, in architecture, SG can work with rules that will convey legal restrictions, space needs and goals of the architect, creating possible solutions to a project. A wide range of solutions can be tested in computational applications based in SG. These applications can also encourage the architect to go further in his creativity through shape emergence where the conditions are fulfilled and presented as innovative and/or unexpected. Architects obey strict rules when they apply artistic intention to a specific need/objective intention (space building). Thus, our methods are to enumerate SG as a tool for decision-making in architectural projects and to show a set of common phases that may be generated by the use of computational applications in response not only to technical needs but also to creative goals.

“…This process for a good interface definition requires a significant amount of time, but time is often scarce when a new application is being developed. This might be one of the reasons why existing SG applications, which require such complex development of algorithms and programming time, still have rudimentary interfaces, as analyzed in our previous work (Tching et al, 2016). This acknowledgment is the basis of our IM-sgi proposal.…”

“…We then rapidly created an interface prototype following IM-sgi criteria that has all the needed considerations to be adjusted to SG users, allowing them to perform the tasks needed to work with SG. Following the Lewis and Rieman's process of nine stages listed above (Lewis & Rieman, 1994), IM-sgi definition of stages 1–3 has already been developed and presented in a previous article (Tching et al, 2016).…”

“…It addresses the types of SG users and the different ways they can relate to the SG applications, pointing out different scenarios that range from a higher control for the user of the system to a higher automation and passivity of the user. Studying these control scenarios, with the aim for architects and designers to be able to use SG in creative projects, we defined three groups of users for the IM-sgi, according to their level of control of SG and their needs for manipulation: students, designers/artists, and SG experts (Tching et al, 2016).…”

“…The use of SG with computer applications enables the designer to take the full advantage of (1) synthesis and analysis of styles in design/architecture/art and (2) the creation of new forms. Several models of interaction with the user have been developed, as the ones developed by Scott Chase (Chase, 2002) and Haldane Liew (Liew, 2002) [see analysis in (Tching et al, 2016)]. These models seem to lack guidelines for a clear and efficient interface for SG implementations that translate the objectives of the existing models of interaction.…”

Information technologies are a driving force for progress in the design field, allowing new modes of creativity. However, most of the existing computational design tools are focused on the latest stages of the design process and especially directed to drafting operations. Conceptual design tools that support the designer in the creative and inventive early stages of the design project are still in their early development. Shape grammars (SG) were introduced by George Stiny in the 1970s, allowing the generation of designs according to a set of predefined rules. SG computational implementations have the potential to answer the need for tools that can assist designers, architects, and artists in the creative process, offering design alternatives, stimulating new ideas and encouraging the search for new design generation processes. Acknowledging this potential, a user-friendly interface seems essential for the adoption of these tools. Taking Scott Chase's interaction model as background, the aim of the present investigation is to define guidelines and begin to design a graphical-user interface for SG implementations. Inspection methods of human–computer interaction (HCI) were used to analyze existing SG implementations and understand usability issues. Subsequently, HCI ergonomic criteria for interface evaluation were adapted to establish guidelines for the design of an SG implementation interface, called IM-sqi. These guidelines take into account different user groups, adjustable interaction modes for each user group, and the nature of each task performed by the user.

This paper describes the visual interface of a configurable and extensible system to support generic work with shape grammars. Shape grammars allow the implementation of computational mechanisms to analyze and synthesize designs of visual languages and have been used to represent the knowledge behind the creative work of architects, designers and artists. This kind of grammars is inherently visual. The system described, a kind of universal machine for shape grammars, allows users to build their own shape grammars and experiment with them. It has been the focus of our past work, it mixes technological and artistic aspects and it has a specific computational architecture which includes a symbolic and a visual interface. The latter one is the subject of this paper.
