The EchoVision glasses can definitely provide assistance in identifying books and periodicals as well as reading them. The current three action (or AI) modes of Scene Description (Q and A), Live AI and Reading Mode offer powerful capabilities in this regard.
In terms of orientation and providing directions to something, the answer is a bit nuanced. The glasses can be a valuable tool in assisting with this, but due to the latency in providing you information it is not recommended that they be used alone as an orientation and mobility tool. User's should always primarily rely on their fundamental orientation and mobility training for that. So long as you understand the limitations of this technology you can learn to use it as a valuable supplement to your O&M skills.
