Proto-TAI++: Exploring perceptually consistent creation of planar shape assemblies through multi-modal tangible interactions

We explore tangible 3D interactions that allow for geometric and perceptual correspondence between a midair modality and the 3D elements it controls. To demonstrate our approach, we use a concrete application scenario through Proto-TAI++, a multimodal system using...
RealFusion: An Interactive Workflow for Repurposing Real-World Objects towards Early-stage Creative Ideation

RealFusion: An Interactive Workflow for Repurposing Real-World Objects towards Early-stage Creative Ideation

We present RealFusion, an interactive workflow that supports early stage design ideation in a digital 3D medium. RealFusion is inspired by the practice of found-object-art, wherein new representations are created by composing existing objects. The key motivation...

PROTO-TAI: Quick Design Prototyping using Tangible Assisted Interfaces

In the real world, we use our innate manual dexterity to create and manipulate 3D objects. Conventional virtual design tools largely neglect this skill by imposing non-intuitive 2D control mechanisms for interacting with 3D design models. Their usage is thus...
Remanufacturing of Turbine Blades by Laser Direct Deposition with Its Energy and Environmental Impact Analysis

Remanufacturing of Turbine Blades by Laser Direct Deposition with Its Energy and Environmental Impact Analysis

Laser direct deposition provides an attractive and cost effective means for repairing or remanufacturing high value engineering components. This study demonstrates the successful repair of defective voids in turbine airfoils based on a new semi-automated geometric...
