I am a PhD student at Max Planck Institute for Informatics (Saarbrücken, Germany), currently conducting research at Computer Graphics Department (D4), under the supervision of Prof. Dr. Karol Myszkowski and Prof. Dr. Hans-Peter Seidel. I hold a bachelor's degree in Electronic and Automatic Engineering from University of Zaragoza, followed by a master's degree majoring in Robotics, Graphics and Computer Vision from the same institution. I also spent some months as research intern at Graphics and Imaging Lab, where I worked with Prof. Dr. Ana Serrano and Prof. Dr. Sandra Malpica. My research focuses on human perception and performance in virtual environments, with particular interest in audiovisual interaction and visual response behavior.

We study how our subjective estimation of speed is influenced by the interaction of factors such as contrast, spatial frequency, temporal frequency and eccentricity. The interplay of such visual cues is observed to impact speed misperception as perceptual biases are found. Based on our collected data, a model is proposed to predict the underestimation or overestimation of perceived speed from visual properties. Finally, our findings are validated in different common VR scenarios and we discuss potential future applications in designing perceptually aligned experiences and correcting speed misperception.
Proceedings of SIGGRAPH 2024
We investigate the temporal and spatial relationship of audiovisual interactions, focusing on how auditory cues that precede visual stimuli influence saccadic latency. Our research, conducted within a virtual reality environment, reveals that auditory cues preceding visual information can significantly accelerate saccadic responses, but this effect plateaus beyond certain temporal thresholds. Additionally, while the spatial positioning of visual stimuli influences the speed of these eye movements, we find that the location of auditory cues with respect to their corresponding visual stimulus does not have a comparable effect. To validate our findings, we implement two practical applications: first, a basketball training task set in a more realistic environment with complex audiovisual signals, and second, an interactive farm game that explores previously untested values of our key factors.

We present a computational and probabilistic model to predict VR users’ reaction latency to visual-auditory multisensory targets. To this aim, we first conducted a psychophysical experiment in VR to measure the reaction latency by tracking the onset of eye movements. Experiments with numerical metrics and user studies with naturalistic scenarios showcase the model’s accuracy and generalizability. Lastly, we discuss the potential applications, such as measuring the sufficiency of target appearance duration in immersive video playback, and suggesting the optimal spatial layouts for AR interface design.
The Visual Computer 2024
We leverage the full control of audiovisual cues provided by VR to study an audiovisual suppression effect (ASE) where auditory stimuli degrade visual performance. In particular, we explore if barely audible sounds (in the range of the limits of hearing frequencies) generated following a specific spatiotemporal setup can still trigger the ASE while participants are experiencing high cognitive loads. Our results show that the ASE is robust to variations in frequency, volume and cognitive load, achieving a reduction of visual perception with the proposed hardly audible sounds. Using such auditory cues means that this effect could be used in real applications, from entertaining to VR techniques like redirected walking.
