“…Gesture interfaces for Virtual Reality (VR) or Augmented Reality (AR) environments provide better immersion and do not require conscious attention dedicated to the specific gestures being performed (Deller et al, 2006). Spatial concepts can be expressed using gestures, and they are used in design and engineering, when externalising ideas (Vinayak et al, 2013). Interaction with comfort functions in a car can be achieved without taking the eyes off the road (Riener et al, 2013).…”

“…While the gesture-based interfaces are being developed for various applications clear standards which could guide their further development are not apparent. For example, while interfaces supporting three-dimensional (3D) object manipulation exploring use of intuitive, affordable and nonintrusive interfaces are ubiquitous, none of the approaches used have been established as the baseline for future development (Vinayak et al, 2013). Investigation of patterns of gesture use, identifying commonalities and differences between different fields would be an initial step towards development of a standard framework for gesture elicitation for interaction interface development.…”

“…Supporting environmental and similarity assessment for novel 3D parts, requires estimation of their geometric properties. Recently developed natural user interfaces for rapid virtual prototyping such as [35,36] are particularly applicable in the this context. These interfaces allow designers to iterate over several designs and can be possibly used to guide sustainability-based decision making.…”

ShapeSift is a framework for supporting sustainability-based decision making during selection of similar previous designs from part repositories. Our framework is designed for 3D part repositories that contain metadata pertaining to materials and manufacturing processes as well as the functionality of a given part. To demonstrate the usefulness of the proposed framework we develop an example multi-dimensional visualization that encodes part similarities as well as a calculated environmental sustainability indicator. This visualization is incorporated in a prototype interface that focuses on enhancing the intuitiveness of the exploration process by the use of sketch-based retrieval.

“…Pointing gesture was used to modify surface by sketching strokes as its new profile. Murugappan et al proposed a framework of using hand geometry information to control the generation of Generalized Cylinder (IGC) [14]. They implemented three gestures -release, grab and point gestures -in the framework and combined them with hand locations to form five modeling operations for controlling different modeling operations.…”

Naturalness of the mid-air interaction interface for virtual assembly and shape modeling is important. In order to design an interface perceived as "natural" by most people, common behaviors and mental patterns for mid-air interaction of people have to be recognized, which is an area merely explored yet. This paper serves this purpose of understanding the users' mental interaction models, in order to provide standards and recommendation for devising a natural virtual interaction interface. We tested three kinds of tasks -manipulating tasks, deforming tasks and tool-based operating tasks on 16 participants. We have found that: 1) different features of mental models were observed for different types of tasks. Interaction techniques should be designed to match these features; 2) virtual hand selfavatar helps estimate size of virtual objects, as well as helps plan and visualize the complex process and procedures of a task, which is especially helpful for tool-based tasks; 3) bimanual interaction is witnessed as a dominant interaction mode preferred by the majority; 4) natural gestures for deforming tasks always reflect forces exerted. These suggestions are useful for designing a midair interaction interface matching users' mental models.
