Redesigning Perception and Computation for Energy-Efficient Physical AI

We aim to realize "AI that can understand the real world as it is and act instantly,” and to uncover the principles of intelligence that operates in the physical world. Current vision-based AI relies on frame-based cameras, treating inherently continuous time and motion as discrete snapshots, which limits the integration of prediction and action. We discard this assumption. Starting from event cameras that capture only moments of change, we build a spatiotemporal perception framework that directly handles the flow of time. Our goal is to enable physical AI that does not “sense, then think,” but rather “thinks while sensing and acts simultaneously.” Furthermore, by co-designing semiconductor hardware to match this new form of perception, we seek to develop biologically inspired, energy-efficient intelligent systems, and to open up further new imaging applications.

Computer Vision, Machine Learning, Spatiotemporal Understanding

We tackle the still underexplored challenge of understanding a continuous and dynamic three-dimensional world, which remains difficult for modern computer vision and AI. In particular, by leveraging event cameras, we analyze data with high temporal resolution and wide dynamic range that conventional frame-based methods cannot capture, and propose principled theories for new spatiotemporal representations and their estimation. As research in areas such as world models and Embodied AI continues to advance, we aim to lead the redefinition of spatiotemporal perception at their core.

Hardware–Software Co-Design for Efficient and Robust, Bio-Inspired Intelligence

How can we achieve the high energy efficiency of biological systems and robust perception in unknown environments? We believe that hardware/software co-design is essential. By jointly advancing processor architectures that fully exploit the characteristics of AI algorithms and rethinking what those algorithms should be based on hardware constraints, we take a holistic approach from sensing to inference. Through this, we seek new principles for realizing intelligent systems that are both energy-efficient and high-performance.

Applications Unlocked by Spatiotemporal Sensing

Spatiotemporal sensing enables the observation of fast, subtle, and non-stationary phenomena that conventional frame-based measurements fail to capture, thereby opening up new application domains. Examples range from fine-scale dynamics, such as air fluctuations (density variations) and neural activity measurements, to non-rigid motion like human movement and sports analysis, as well as the realization of high-bandwidth, low-latency distributed communication in visible light communication systems. We aim to create new applications in measurement and communication using image sensors.
