This webinar lasted 60 minutes and included an opportunity to pose questions to the guests. The panel were able to answer many questions from attendees during the live session, which you can find by watching the webinar playback or accessing the transcript. Here are some additional questions we weren't able to answer at the time:

Q: Just out of curiosity, how much do wearables usually cost? 

Alex from AbilityNet: Wearables start at less than £50 for a smartwatch but for smart glasses that are accessible to blind users expect to pay at least £1500.  This is because of the added functionality that they have.

Q: Does the Soundscape app know which direction your head is looking when it uses binaural sound directions? 

Davinder from RNIB: If using supported accessories such as apple Air  Pods yes it does. This is because the supported headset needs to have additional sensors in it to enable them to carry out this task independently of the phone. Supported headsets are listed on the app and online details. 

Q: Does "Specialised Help" in the ‘Be My Eyes’ app work with non-Apple devices?  

Davinder from RNIB: The specialised help is available via the Be My Eyes platform. The app works on both apple and android and therefore once logged in and registered on any platform of choice, the user has access to the specialised help section.

Q: Can you change the speed of the Envision glasses because it talks very quickly?

Karthik from Envision: Yes, the speed, volume, and voice can be changed on the glasses.

Q: Does the Envision glasses read only the text on an email or would it recognise also the images?

Karthik from Envision: The Glasses can read text, recognize objects, faces, cash, light and even colours.

Q: Can "scan text" read hand-written documents?

Karthik from Envision: The Glasses can read handwritten documents in more than 60 differnet languages. Including cursive handwriting.

Q: Is the reader always on the right hand side or can be be on the left?

Karthik from Envision: The reader is always on the right hand side but you can also use your voice to operate the Glasses.

Q: Can everybody hear the audio or just the person using the glasses?

Karthik from Envision: The speaker is located next to your right ear so it’s mostly only audible to you. Having said that, you can always connect the Envision Glasses to any bluetooth headphones or speakers. That way the audio is only available to you.

Q: Can you refer us to ANY independent current reviews of excellent inexpensive android tablets for use by elderly people with “heavy hands” and inexperienced with such devices? And that can be used with screen readers … with good / loud “audio.”

Alex from AbilityNet: If you would like to call our free phone help line 0800 048 7642, I can support you with some advice and information on this.
