1.1. Background 1 3 Box 1: The components of a visual prosthesis 1. A camera captures the visual information from the surroundings. While alternative solutions such as intra-ocular sensors are being explored, most designs feature a head-mounted camera, worn on a pair of glasses. The implications of using head-steered visual input are further investigated inChapter6. 2. The mobile computer processes the camera frames, and decides how the brain should be stimulated. The mobile computer makes use of intelligent scene processing algorithms that extract the most relevant visual features from a scene. The evaluation of efficient scene processing algorithms is a central theme in this dissertation, and plays a particular prominent role inChapters2 to4 3. The neural interface consists of electrode arrays that stimulate neurons in the visual pathway. Our research focuses on intracortical prosthetic interfaces that have many electrodes implanted in the primary visual cortex (V1). The perceptual effects of electrical stimulation in the primary visual cortex are studied inChapter5. Elements in this figure were created with generative AI (seeSauer et al., 2022). Prompts: “a person with glasses looking sideways” and “a busy city scene with a tram”.
