Hi, I'm trying to help a visually impaired friend and make her home more accessible. I know there's voice activation technology out there, from mobile phones to smart TVs and Alexa etc but don't really know how to get started and don't want to recommended the wrong things. She's also considering Hive heating. Does anybody know of a dummies guide or a service which could help? The RNIB and Guide Dogs websites have helped to a point but the technology seems to be updating quicker than the websites. We don't have any local shops to visit for help. Thank you
