Ask Envision is a virtual assistant feature on Envision Glasses that uses GPT-4 by OpenAI to answer natural language questions about text-based content, enhancing accessibility for people with visual impairments.
I was one of the early testers of this feature and its works unbelievably well. Makes it really easy to understand the context and obscure details about the scanned content that would normally be difficult to grasp for low vision or a visually impaired person.
