Haptically extended augmented prototyping

Abstract. We here describe a novel approach for locally obtaining pose estimation of match feature points, observed using RGB-D cameras, in order to apply to locally planar object pose estimation with RANSAC method for augmented reality systems. Conventionally, object pose estimation based on RGB-D cameras are achieved by the correlation between observed 3D points captured by feature point matching and known 3D points of the object. However, in such methods, features are simplified as single 3D points, losing information of the feature and its neighborhood surface. This approach based on local 3D pose estimation of locally planar feature points, brings richer information for 3D pose estimation of planar, 3D rigid or deformable objects. This information enables more stable pose estimation across RANSAC settings than conventional threepoints RANSAC methods.

“…Caruso and Re have developed an interactive AR system called 'Video See Through Head Mounted Display' for visualizing and interacting with virtual designed objects to be able to review and offer feedback to objects for further design improvement[79] (Figure 2.65). Dima et al presented a display concept which uses AR with haptic feedback that allows designing of virtual geometry[80]. Santos et al has proposed using digital tape in…”

Appraisal of Augmented Reality Technologies for Supporting Industrial Design Practices

, 150 pages Augmented reality (AR) is a technology that enables the integration of computer generated data into real objects and environments. With the rapid advancements in technology, uses of AR have also become widespread. Nowadays, digitally created data including videos, images, sound, 3D models and text can be viewed superimposed on the real objects/environment through devices such as personal computers, tablets, smartphones, head mounted displays, and projection. AR also offers potential uses for industrial designers, especially for design students. Some design stages, during which traditional tools and methods are used by designers, may not fully convey the total experience that a designed product offers, like audiovisual feedback and digital interfaces. AR can help by providing a digital layer in which designers can present information and make their presentation more interactive. Therefore, the present research aims to offer directions for industrial designers to use AR technology in design activities to enrich their workflow. A fieldwork with three progressive studies was conducted i) to create awareness of AR to imagine uses for AR in the design process; ii) to explore the potential of mobile AR apps in a design project in an educational setting; iii) and to offer solutions for the future uses of the technology by industrial designers. The fieldwork is undertaken in an educational setting to evade limitations of professional design setting such as time constrains, budget and marketing. The results show that AR can be utilized mainly in presentation and v prototyping stages of design process and with further development in the technology, AR might be useful for several other design activities such as scenario building, user tests, project research, material and mechanical considerations, product surface creation, and so on.

“…In addition, a draw function can be implemented through which users can draw extra geometry. In [9] an early research on this process is presented, and the Virtual Showcase [3] that was mentioned in the literature review also allows the presentation of stereoscopic images overlaid on top of real objects. We envisage that this study will have numerous applications in museum research as well as learning.…”

Touching the Past: Haptic Augmented Reality for Museum Artefacts

In this paper we propose a novel interaction technique that creates the illusion of tactile exploration of museum artefacts which are otherwise impossible to touch. The technique meets the contextual necessity, often requested by museum curators, to background technology and to direct the focus of the museum visitor's experience to the artefact itself. Our approach relies on the combination of haptic interaction and the adaptation of a well-known illusion that enables museum visitors to make sense of the actual physical nontouchable artefact in an embodied way, using their sensory and motor skills. We call this technique Haptic Augmented Reality.
