What about an Alexa type device(s) that you/she can initiate voice or video calls with? You can setup stuff like medication reminders and probably tons of other options.
If you fall and can't get up, you can call a buddy for help through Alexa.
Alert feature
You can't predict when you'll need help, Ask My Buddy lets you immediately alert someone in your Personal Alert Network that you need them to check on you. You may alert just 1 or all of your contacts with just one command. Simply say, 'Alexa, Ask My Buddy to alert YourContact' or 'Alexa, Ask My Buddy to send help', and Ask My Buddy will immediately send an alert, notifying them to check on you right away. Alerts will be sent by text message, an email, and a voice telephone call.
Premium users can let Contacts know what type of help they may need just by saying a few more words after the Send Help command. Contacts will receive the added information in each text message, email, and voice call. ‘Alexa, Ask My Buddy to Send Help I have fallen and am on the floor’
Check In feature
Have you wished that you could easily let your family that you are doing ok? Ease their minds with a 'Check In' message to your contact by saying "Alexa, Ask My Buddy to check in with yourContact" or you can check in with all of your Contacts at once. Check In messages are sent the same way alerts are, by text message, an email, and a voice telephone call. Use Check In messages each day to let your family know you are doing OK, or use the Check In after you return from taking a walk, even kids can use it to let parents know they arrived home from school.
Ask My Buddy is not a substitute for 911, but rather an additional tool offering the security of knowing help is just a shout away.
