“…A number of these modelling media have been studied more deeply, Varga (2007) and Hummels (2000) did extensive research about using hand motions in conceptual shape design and the use of gestural design tools. Shillito et al (2003) and Cheshire et al (2001) have studied the impact of haptics in a digital design environment; Scali et al (2002) investigated the potential benefit of 'gestural' and haptic (touch) interaction and stereovision in computing for threedimensional form conceptualisation and spatial reasoning in the germinal phase of the design process.…”

“…Within the field of the former, according to Varga (2007), the use of design support systems is proliferating and from time to time, new paradigms and technologies appear in practice. A general issue for research is how to create a bridge between the design thinking of humans and the systematic modelling process imposed by computers (Krause et al 2004).…”

This article presents a 'hands-on' method, targeted towards freshmen product development (or industrial design or engineering design), to create basic form alternatives. The hypothesis that the knowledge and the application of a rational form-generation approach improve the ability to create more and more varied designs is verified by means of an experiment. In this experiment, the effectiveness of the initiated method was measured by comparing the results of a first design session (before initiation of the method) with the results of a second design session (after initiation). The outcome shows definite progress in the basic skills to generate form alternatives: after the initiation, subjects generate more proposals with more variation in surface composition. Parameters like the overall amount of design solutions and the evolution in the variation in surface composition were considered. The experiment indicates that the application of a method can enhance a design process and shows that an analytical and rational approach contributes to the basic skills in the study of form. The two-step manipulation method extends the repertory of possible tools and methods that a designer can implement to cope with the problems concerning the creation of form alternatives.

We present a paradigm for natural and exploratory shape modeling by introducing novel 3D interactions for creating, modifying and manipulating 3D shapes using arms and hands. Though current design tools provide complex modeling functionalities, they remain non-intuitive for novice users. Significant training is required to use these tools since they segregate 3D shapes into hierarchical 2D inputs, binding the user to stringent procedural steps and making modifications cumbersome. On the other hand, the use of CAD systems is typically involved during the final phases of design. This leaves a void in the early design phase wherein the creative exploration is critical. We present a shape creation paradigm as an exploration of creative imagination and externalization of shapes, particularly in the early phases of design. We integrate the capability of humans to express 3D shapes via hand-arm motions with traditional sweep surface representation to demonstrate rapid exploration of a rich variety of 3D shapes. We track the skeleton of users using the depth data provided by low-cost depth sensing camera (Kinect TM). Our modeling tool is configurable to provide a variety of implicit constraints for shape symmetry and resolution based on the position, orientation and speed of the arms. An intuitive strategy for shape modifications is also proposed. Our main goal is to help the user to communicate the design intent to the computer with minimal effort. To this end, we conclusively demonstrate the creation of a wide variety of product concepts and show an average modeling time of a only few seconds while retaining the intuitiveness of the design process.

“…Recently, Holz and Wilson [5] gave an interesting and comprehensive description of how natural gesticulation is critical in description of spatial objects. While 2D artifacts like sketches and drawings are better-off being created with 2D interfaces, the creation of 3D shapes using 2D interfaces limits the capability of designers to experiment at conceptual and artistic levels [6]. Creation of organic and free-form shapes had been shown in literature using glove-based [7] and augmented reality interfaces [8].…”

We present the paradigm of natural and exploratory shape modeling by introducing novel 3D interactions for creating, modifying and manipulating 3D shapes using arms and hands. Though current design tools provide complex modeling functionalities, they remain non-intuitive and require significant training since they segregate 3D shapes into hierarchical 2D inputs, thus binding the user to stringent procedural steps and making modifications cumbersome. In addition the designer knows what to design when they go to CAD systems and the creative exploration in design is lost. We present a shape creation paradigm as an exploration of creative imagination and externalization of shapes, particularly in the early phases of design. We integrate the capability of humans to express 3D shapes via hand-arm motions with traditional sweep surface representation to demonstrate rapid exploration of a rich variety of fairly complex 3D shapes. We track the skeleton of users using the depth data provided by lowcost depth sensing camera (Kinect TM ).

Intuitive strategies for coarse and fine shape modifications are also proposed.
