Summary

This internship will explore neural-network-based representations for the encoding, representation, generation, and manipulation of haptic data. It will build on previous work on Implicit Neural Representations (INRs) for haptics and on probabilistic haptic rendering, with the objective of investigating learned representations that support both compact encoding and controllable transformation of haptic effects.

The work will compare architectures such as autoencoders, Generative Adversarial Networks (GANs), and INRs for sample-based and/or parametric haptic data. Beyond reconstruction, the intern will investigate selected manipulation and generation tasks relevant to haptic authoring, including filtering, interpolation, completion/inpainting, temporal extension, and real-time procedural generation. Candidate methods will be assessed in terms of reconstruction quality, controllability, generalization, and computational cost.

The internship may build on recent internal work on haptic effect analysis and temporal extension to explore data-driven approaches for generating missing or extended haptic content. Target use cases may include gaming and haptic authoring tools. The work may lead to prototype software, internal demonstrators, and potentially publication and/or patent contributions.

Responsibilities

The intern will join the haptics research team within the New Media Codec group at InterDigital (Rennes). The work will consist in:

Studying the state of the art on neural representations and generative models for haptic and temporal signals, including autoencoders, GANs, and INRs

Designing and implementing neural representations for encoding, reconstruction, and controllable manipulation of sample-based and/or parametric haptic effects

Exploring selected authoring and generation tasks such as filtering, interpolation, inpainting/completion, temporal extension, and real-time procedural generation

Evaluating the proposed methods and developing demonstrators for haptic authoring or gaming, with potential contributions to publications and patents
