Questions about Nexa

Nexa is designed primarily for people with low vision who continue to use mainstream computers but find conventional interfaces increasingly difficult to navigate. This includes people with conditions such as age-related macular degeneration, glaucoma, diabetic retinopathy, inherited retinal conditions, and other causes of reduced vision.

Rather than replacing visual interaction altogether, Nexa helps people who still have usable vision perform everyday computer tasks more easily. While its initial focus is low vision, many of the underlying ideas may also prove useful to others who experience friction with everyday computer use.

The need is significant. The World Health Organization estimates that at least 2.2 billion people globally have a near or distance vision impairment, with most people affected being over the age of 50. While many cases can be prevented or addressed through eye care, millions of people continue to live with vision loss that affects their independence and ability to use digital technology.

Computers are now central to communication, access to information, work, services, and everyday life. For people living with vision loss, digital accessibility is therefore an important part of maintaining independence. This can be especially true for people who develop vision loss later in life, after years of using conventional computer interfaces.

Nexa focuses on one part of this wider challenge by helping people use mainstream computers more easily and remain more independent.

Screen readers are invaluable for many people who are blind or have profound vision loss, and Nexa is not intended to replace them.

However, many people who lose vision later in life still have usable sight and are accustomed to using computers visually. They often rely on accessibility features such as magnification, larger text, high-contrast themes, or speech while continuing to use familiar applications. For some, building on those existing skills feels more natural than moving to an interaction model that relies primarily on listening and keyboard shortcuts.

Nexa is designed to complement usable vision and existing accessibility features by making common computer tasks easier to perform with short, natural voice commands. It builds on familiar applications and workflows, helping people continue using mainstream computers with greater confidence and independence.

Voice is one of the most natural ways to express intent, so it is where we are beginning.

Over time, we are interested in exploring other ways of triggering and guiding actions as well.

No. Nexa currently works with a microphone and standard computer hardware.

We are also exploring external devices in the implementation, including a foot pedal, and remain open to other possibilities. Reach out if you have an idea or a use case where another input method could help.

The current prototype runs on Windows.

The longer-term goal is to support computers more broadly rather than being tied to a single operating system.

General-purpose assistants are designed for open-ended questions, content generation, reasoning, and broad task support.

Nexa starts from a narrower problem: how to make everyday interaction with the computer itself simpler, more direct, and more predictable.

We do not want to conflate a technology with the problem we are trying to solve.

Nexa will use the technologies that best support a natural, dependable, and understandable interaction. The technology matters only insofar as it improves the experience.

Nexa is a working prototype. It is usable today for a small set of interactions, and we are continuing to learn which workflows are most useful in practice.

We are looking for people and organisations willing to explore these questions with us through feedback, co-design, and small pilots.

Nexa begins with short, natural voice commands and a small set of dependable actions.

We want to learn from people with low vision, rehabilitation professionals, accessibility organisations, and real use cases before deciding what the interaction should become next.
