There can be financial barriers to testing and it can seem overwhelming.īy coming into the lab people not only see and test the technologies, but also learn what testing they can do in their own workspaces for free. We know that some public sector organisations, especially local government, can struggle to get access to assistive technologies. Since we blogged about the lab, we’ve seen a huge increase in visitors coming in to use it as an assistive technology space. GDS’s Accessibility Empathy Lab is open to anyone from the public sector.
