I am a research fellow in Interactive Graphics at the Interact-lab from the University of Sussex. Under the supervision from Prof. Sriram Subramanian, I completed my PhD on computational 3D interaction techniques for immersive Virtual Reality.
Before joining to the Interact-lab, I received my MSc in Electronics at the National Institute of Technology of Mexico.
I am interested on optimisation techniques to improve human factors in Virtual Reality. I am currently working on the principles of wavefront manipulation and metamaterials to explore a combination of acoustic levitation, mid-air haptics and parametric audio.

VR applications are widely used, involving increasingly challenging conditions such as realism, the feeling of presence and comfort. Full body tracking interactions improve naturalness in VR interfaces. Nevertheless, this kind of interactions involves large movements resulting in high physical effort. Erg-O project introduces “Ergonomic Retargeting” which focusses on improving user’s comfort in full body interactions in VR by warping the 3D space with controlled distortions reducing user’s movement ratios (reducing effort) and hacking users perception to create the illusion of interaction with all elements in the original place.
NaviFields quantifies the requirements for precise navigation of each point of the environment, allowing natural navigation within relevant areas, while scaling users’ displacements when travelling across non-relevant spaces. This expands the size of the navigable space, retains the natural navigation metaphor and still allows for areas with precise control of the virtual head.
We present an approach for the semi-automatic generation of gesture mappings for devices with low gestural resolution such as the Myo Armband, an off-the-shelf EMG capture device. As an exemplar interactive task, we use text-entry: a pervasive and highly complex interaction. We quantify data related to interaction combining systematic studies (i.e., error, speed, accuracy) and semi-structured workshops with experts (e.g., cognitive load, heuristics). The results indicate that our hybrid approach can yield better results than either pure user-driven methodologies or pure data-driven approaches, for our application context featuring a large solution space and complex high-level factors.
