When users face difficult situations, they can press the function key of the WeVoice Glasses to switch to video call mode. Available volunteers can choose to answer the call and the first volunteer who takes the call will be connected to the user. When they are having video call, volunteers can view users’ surroundings through the glasses' camera. Furthermore, with the use of speaker and microphone installed on the glasses, volunteers can provide appropriate audio assistance to the users. Our new version of WeVoice Glasses can also help users identify texts, banknotes and colors to bring them more favors.
