Alexa skills can already do a lot of these voice activated actions. For example, I can ask Alexa to find my phone or call someone directly. With some additional accessories it can even turn on and off lights, outlets, garage doors and more.
What’s interesting is that elderly people can actually have fun interacting with Alexa by asking questions about history, tell jokes and just remind them of something.
Since Alexa keeps improving overtime and over the air with new skills, I don’t really see a need for a special device for elderly. It is getting cheaper and better every day.
