| Outline of Research at the Start |
This project will clarify the meaning and importance of active perception. It will do so by 1) conducting a systematic literature review and meta-analysis of existing evidence on comparing active and passive perception and 2) behavioral experiments inquiring into different aspects of active perception. The results of this project will inform further theoretical developments, lead to more refined experiments into perceptual mechanisms, and have implications for the design of sensory and motor augmentation and rehabilitation devices.

| Outline of Final Research Achievements |
This project explored the benefits of active vs. passive perception by means of a systematic literature review and a behavioral experiment. Our systematic review identified 86 relevant studies from four different sensory modalities. We extracted data that allowed us to relate perceptual outcomes to task specifics and found that while active perception generally improves perceptual accuracy, results vary significantly by sensory modality and task. In our behavioral experiment, we used a 2D object size estimation task with an interface composed of a robotic arm and sensory substitution device. Results indicated that cognitive involvement enhances perceptual accuracy, but no significant difference was found between active and passive modes of exploration. The study also highlighted the need for improved experimental interfaces for more comprehensive research.

| Academic Significance and Societal Importance of the Research Achievements |
The research advances understanding of how active and passive exploration impact perceptual performance, contributing to cognitive science. It also informs the design of perceptual interfaces, sensory substitution devices and rehabilitation programs.
