Assistive technology and environmental control systems help disabled people to use appliances within their homes. I have an environmental control system from a company called Possum, which provides various pieces of assistive technology. I was referred to Possum by an occupational therapist with the NHS, and the company came out to install a system. I have a Vivo which is akin to a smart speaker. It performs similar functions to smart speakers but it works via infrared rather than through the internet, and with a micro button (a clicker in my case) which is connected directly to the Vivo or to a wireless receiver box.
The Vivo is very useful as I can use a single button to perform multiple tasks at home fully independently. I can turn on lights, use the radio, answer an intercom, and phone people. It also allows me to call for assistance and help when I need it. Furthermore, it can be programmed based on your needs such as controlling a television or even opening curtains, or your front door should you want to get the tech installed. In addition to the Vivo, I have a hand-held pager as another way to communicate with my parents as I can ring it through the Vivo system.
Possum have been very helpful when it comes to support, and they come and service the product each year and deal with any problems. I have had it for about 2 years and I would really recommend checking it out if you are interested. It definitely gives me more independence and it is very simple to operate and maintain.
