What is the Internet of Things (IoT) and what does it mean for Assistive Technology?

What is the Internet of Things (IoT) and what does it mean for Assistive Technology?

The term "Internet of Things" (IoT) has become quite popular in recent years, and for good reason. With the increasing availability of low-cost sensors and devices that can communicate over the internet, the IoT has the potential to transform our daily lives, from the way we interact with our homes to the way we manage our health. But what does the IoT mean for assistive technology (AT)? Let's take a closer look.


First, let's define what we mean by assistive technology. AT is any tool or device that helps people with disabilities or limitations to perform tasks that they might otherwise find difficult or impossible. This can include everything from mobility aids, such as wheelchairs and walkers, to communication devices and software that help people with speech or hearing impairments. AT can also include devices that help people manage chronic conditions, such as insulin pumps or medication reminders.


So, how does the IoT fit into this picture? At its core, the IoT is all about connectivity. It's about connecting devices and sensors to each other, to the internet, and to the cloud. This connectivity can enable all sorts of new capabilities, such as remote monitoring, real-time data analysis, and automated control of devices and systems.


For people with disabilities, the IoT has the potential to provide new levels of independence, convenience, and safety. Here are just a few examples:


  • Smart home devices: IoT-enabled devices such as smart thermostats, lights, and door locks can be controlled remotely, via voice commands, or through automated routines. For people with mobility limitations, this can make it easier to manage their homes and perform daily tasks. For example, a person with limited mobility could use a voice assistant like Amazon Alexa to turn on the lights, adjust the thermostat, and unlock the front door, all without having to get up from their chair.


  • Wearable sensors: Many IoT devices are small, low-power sensors that can be worn on the body. These sensors can collect data on a person's activity level, heart rate, sleep patterns, and more. This data can be analysed in real-time to provide insights into a person's health and well-being. For example, a person with Parkinson's disease might wear a sensor that detects tremors and sends an alert to a caregiver if the tremors become severe.


  • Medical devices: Many medical devices are now equipped with IoT capabilities. For example, a glucose meter for people with diabetes might connect to the internet and send data to a cloud-based app. This app could analyse the data and provide insights on how to better manage blood sugar levels. Similarly, an inhaler for people with asthma could track usage and send alerts when it's time to refill the prescription.


Of course, there are also challenges to be overcome when it comes to the IoT and AT. For example, privacy and security are major concerns when it comes to collecting and sharing sensitive health data. Additionally, the complexity of IoT systems can be daunting, especially for people who are not tech-savvy.


Despite these challenges, the potential benefits of the IoT for assistive technology are enormous. As more and more devices become connected, and as the technology becomes more mature and user-friendly, we can expect to see a wide range of new AT products and services that harness the power of the IoT. Whether it's making homes more accessible, improving health outcomes, or enhancing communication and social interaction, the IoT has the potential to transform the lives of people with disabilities in profound ways.
