Research Interests

Vinayak works at the interface of three disciplines: geometric modeling, human-computer interactions and design research. Broadly, he is interested in investigating the role of mixed-initiative interactions for augmenting human expression and creativity in product, industrial and engineering design. The central objective of his research is to enable expression of design intent for idea generation during early phase conceptual design. To this end, his work involves development of new techniques in computer-aided design (CAD), geometry & image processing, information visualization for conceptual design, mobile & wearable interfaces for creativity support, computer-aided ergonomics, and AR/VR (augmented and virtual reality) interfaces for design.
