Extended reality (XR) technologies have transformed humancomputer interaction through immersive overlays, spatialized cues, and adaptive rendering [1, 40, [7]]. Yet these systems presume intact vision, effectively excluding over 40 million people with incurable blindness [[24]]. Visual neuroprostheses seek to restore a…

This paper describes a novel bionic eye binocular vision system designed to mimic the natural movements of the human eye. The system provides a broader field of view and enhances visual perception in complex environments. Compared with similar bionic binocular cameras, the JEWXON BC200 bionic binocular camera developed…

Degenerative diseases of the retina produce a severe deterioration in visual perception. Visual prostheses enable partial vision restoration by eliciting phosphenes (perceived spots of light) through electrical stimulation. By using augmented reality (AR) to simulate bionic vision (SBV), this study aims to provide…

Efforts to restore vision via neural implants have outpaced the ability to predict what users will perceive, leaving patients and clinicians without reliable tools for surgical planning or device selection. To bridge this critical gap, we introduce a computational virtual patient (CVP) pipeline that integrates…

By 2020 roughly 200 million people worldwide will suffer from photoreceptor diseases such as retinitis pigmentosa and age-related macular degeneration, and a variety of retinal sight restoration technologies are being developed to target these diseases. One technology, analogous to cochlear implants, uses a grid of…

Retinal degenerative diseases cause profound visual impairment in more than 10 million people worldwide, and retinal prostheses ('bionic eyes') are being developed to restore vision to these individuals. Analogous to a cochlear implant, these devices convert video from a head-mounted camera into electrical pulses used…

Retinal degenerative diseases such as retinitis pigmentosa (RP) and age-related macular degeneration (ARMD) lead to a gradual loss of photoreceptors in the eye that may cause profound visual impairment in more than 10 million people worldwide. Analogous to cochlear implants, retinal neuroprostheses (also known as the…

The World Health Organization has estimated that by the year 2050, roughly 114.6 million people will be living with incurable blindness and 587.6 million people will be affected by severe visual impairment . Although some affected individuals can be treated with surgery or medication, there are no effective treatments…

'Michael Beyeler'] Over the past decade, extended reality (XR) has emerged as an assistive technology not only to augment residual vision of people losing their sight but also to study the rudimentary vision restored to blind people by a visual neuroprosthesis. A defining quality of these XR technologies is their…

–This work presents a bunched of promising technologies to treat blind people: the bionic eyes. The strategy is to combine a retina implant with software capable to interpret the information received. Along this line of thinking, projects as Retinal Prosthetic Strategy with the Capacity to Restore Normal Vision from…

The “bionic eye” – so long a dream of the future – is finally becoming a reality with retinal prostheses available to patients in both the US and Europe. However, clinical experience with these implants has made it apparent that the vision provided by these devices differs substantially from normal sight. Consequently…

—Biology can provide biomimetic components and new control principles for robotics. Developing a robot system equipped with bionic eyes is a difficult but exciting task. Researchers have been studying the control mechanisms of bionic eyes for many years and considerable models are available. In this paper, control…

Introduction: Retinal implants have now been approved and commercially available for certain clinical populations for over 5 years, with hundreds of individuals implanted, scores of them closely followed in research trials. Despite these numbers, however, few data are available that would help us answer basic questions…

The enabling technology of visual prosthetics for the blind is making rapid progress. However, there are still uncertainties regarding the functional outcomes, which can depend on many design choices in the development. In visual prostheses with a head-mounted camera, a particularly challenging question is how to deal…

Photoswitches exhibiting large structural variation, visible light responsiveness, and multifunctionality are important for both chemistry and bionics research. However, beyond the limited variety of functional motifs, removing high-energy UV light in photoactivatable systems remains a challenge. Herein, we report a…

Symbiotic corals have evolved as a highly optimised photon augmentation system leading to space-efficient microalgal growth and photosynthetic quantum efficiencies that approach theoretical limits^1–3^. Corals are characterized by an elastic animal tissue hosting microalgae and a light scattering calcium carbonate…

A longstanding engineering ambition has been to design anthropomorphic bionic limbs: devices that look like and are controlled in the same way as the biological body (biomimetic). The untested assumption is that biomimetic motor control enhances device embodiment, learning, generalization, and automaticity. To test…
