Solutions for the visually impaired.

Former Member

Hi! My name is Eric. I am moderately visually impaired and I have a question. I have a friend who is completely blind and has a child who is just starting to run around and tries to get into trouble (Of course she doesn't see it as trouble, she's just having fun)! image However, sometimes it is difficult to keep track of the child, and know if she's somewhere she shouldn't be. Does anyone have any ideas on what could help her out? I'm thinking of some type of system that would notify her if the child is going somewhere in the house she shouldn't be without supervision. But also will let her find her if she goes somewhere to hide, or just falls asleep on the floor so she doesn't trip over her. Maybe even tell her the child's location in the house. Suggestions on existing products, or parts that could be used to make the product are welcome. This will be an indoor application, so GPS is probably out. Also, would like something relatively inexpensive. Thanks for your time, and for any suggestions. Eric..

    How about a bell tied to the back of a wearable clothes. Sound can be picked up by mics located at various places around the house connected to a microcontroller with bluetooth. A simple app on a phone can be used collecting the info.

    Hi Eric

    How about putting a belt on the child with a module that emits a low frequency noise every couple of minutes. Low frequency travels distances well and isn't obnoxious. The unit could have a separate receiver where the mother could push a remote button to manually trigger the sound when necessary.

    Thanks for the reply. Sound is definately one of the solutions I'm considering. My only concerns would be that the child will hear the device and think it's a toy and take it off. Also, I don't know if I could use the sound to accurately find the child in a room if she's asleep. The big thing is the mother is worried about is finding the child without getting on hands and knees and exploring the room. I really appreciate you taking the time to respond to my post. Thank you.

    You could try Bluetooth beacons. For example, installing a beacon in a place where the child should not be for starters. You can adjust the transmit power to cover a certain radius (as in area of the room/house etc) and every time the child is within the beacon area it triggers an event like a general alarm that the child would recognize as an area which is off limits for her while helping the mother know where in the house she is. Different areas could have different variations of the alarm to enable the mother to know her precise location.

    Of course the child would need to have a beacon like bracelet or something similar on her all the time. But when the wearable does not make any sound or show any sort of display, it is unlikely the child will suspect it, find it to be a nuisance and take it off.

    I can help you create and install this system, feel free to write to me if you want more info.

    How about a Panasonic Grid-EYE IR sensor in each room ?

    It should be able to indicate where the child is currently is located in a room unless they are able to crawl under something. Even then you could use the last known detected position to work out where they hid.
