What assistive technology is available?

Find out what items of assistive technology you can get hold of and what they do.

There are many different technologies that can be adapted to the needs of someone with dementia. Some pieces of assistive technology have been designed specifically for people with the condition but a lot of potentially helpful technology has not. Friends and family may already be using products or devices that could benefit a person with dementia.

This page gives an overview of some of the technologies, devices and services available, but does not go into detail about every type. Your local council social services, an occupational therapist or assisted living centre can provide advice and information on what is available locally.

Some types of technology may not be needed immediately, but it can be helpful to know what is available and what may be able to help in the future. Some of the devices may be used for more than one purpose, and how they are used will depend partly on the person who is using them.

Daily living

These are devices that help someone who has difficulties with memory loss, orientation or communication that are affecting their daily life.

Automated prompts and reminders

One type of reminder, based on a motion sensor, plays a pre-recorded voice prompt when there is movement nearby. For example, a sensor placed near the front door could remind someone to lock the door, or one in the kitchen could remind someone to turn the oven off.

Another kind of reminder does not detect movement but is set to play a message at a certain time. For example, someone may record a message reminding them to take their medication or telling them that they have an appointment. They could also set their phone calendar to remind them.

Technology now also allows family members or other people not living with the person with dementia to access a tablet in the person’s home and support them with reminders. This means the person with dementia has a display of appointments, visitors and activities, as well as the reassurance of knowing where people who can help are and how to contact them.

Clocks and calendars

There are lots of products available to help people with dementia keep track of the day and date. Automatic calendar clocks can be helpful for people who lose track of which day it is. Many show both the date and day of the week. Some clocks also show clearly whether it is morning or evening. These can help prevent people getting confused about the time, particularly in the light summer evenings. Clock and calendar apps can also be downloaded for tablets, which you can set up to suit your own tastes and needs.

Medication aids

There are lots of different medication aids available. It may help to talk to a pharmacist about the best option. Simple boxes for pills (known as dosette boxes) have separate compartments for days of the week and times of day (for example morning, afternoon, teatime, bedtime). They can help people remember to take their medication on the right day and at the right time, especially in the early stages of dementia. Simple versions are available from the local chemist.

Automatic dispensers for pills that are taken regularly are also available. These are pre-filled – ask your local pharmacist whether they offer this service – and then locked. When the medication needs to be taken, the dispenser sets off an alarm and the right compartment opens, allowing the person to access their medication. The alarm may continue until the pills are removed from the dispenser. There are also devices that can send an alert to a friend or relative to notify them if the medication hasn’t been taken, or if the device isn’t working, has low battery or needs refilling.

Locator devices and solutions

These can be used to help someone find things they regularly misplace, such as keys or a wallet. A small electronic tag is attached to each item. In one system, the person has a dedicated locator device and, if they mislay the item, they can click a button on the locator device to make the tag beep.

The locator device will need to be kept somewhere obvious. These systems can be confusing and difficult to use for some people with dementia. They may be more helpful for carers, or when carers are able to support the person to use them.

An alternative (and less intrusive) approach is to attach a small tile to each item and link these to a smartphone using a simple app. One system like this stores the last place your phone ‘saw’ the tile. This location can then be displayed on the phone’s map function.

Communication aids 

These can support people with dementia to stay in touch with others. The most common type of devices are adapted telephones. These can be pre-programmed with frequently used numbers. The person can then call a friend or relative by pressing a single large button or a button with their photo on it. Some telephones are even designed so only preset numbers can be dialled. Many smartphones also offer this option using their touch-screen function.

Another option is video chat, where people talk to and see each other via a computer, tablet or smartphone. These technologies – which include the well-known Skype service – are free to use once both parties are set up, although you will need to have internet access.

For a person who has problems with speech, communicating using cards that combine pictures and text may help. Someone caring for the person might use these cue cards to offer different options for an activity, for example. The person would then point or nod to choose the one they want.

Talking mats is a popular app which takes this idea onto a tablet or computer. People can communicate how they feel, or who they want to spend time with – for example, by selecting the picture or symbol from the options offered. Talking mats is increasingly used to engage people with dementia living in care homes.

It is important that people with dementia can feel safe in their home, especially if they live alone. Technology that supports someone to remain safe can help them to stay living at home for longer. Often safety devices can be linked to telecare systems (see ‘Telecare’ below).

Technology designed to support a person’s safety includes the following:

  • Automatic lights that come on when the person is moving around. They can help to prevent trips and falls.
  • Automated shut-off devices that can stop the gas supply if the gas has been left on, or turn off a cooker if it’s been left on. These may need to be installed, which may cost money, and there may be costs for reconnecting the gas supply.
  • Water isolation devices that can turn off a tap if it’s left running, preventing flooding.
  • Special plugs that allow users to choose a certain water depth in a sink or bath. If the water goes above that level, the plug opens and the water drains. They can also include a heat sensor that changes the colour of the plug when it reaches a certain temperature. This can help prevent floods and scalds.
  • Fall sensors that can register if a person has fallen.
  • Telephone blockers that can be used to stop nuisance calls.

Safer walking

People with dementia may have a need to walk about. Often this is not a problem for the person – they may find it a positive experience, and walking can have both physical and psychological benefits for them. However, there may be times when walking does present risks, such as the person getting lost or leaving the house during the night when they are not appropriately dressed. Carers may find this walking behaviour difficult.

Some people may consider safer walking devices or apps. These need to balance the aim of keeping a person safe with restrictions to their privacy. Types of safer walking device include:

  • An alarm system– This provides an alert when someone has moved outside a set boundary (for example the front garden). These devices cannot locate a person.
  • Tracking devices or location monitoring services – These use satellite or mobile phone technology to locate and track the person. The types of devices include watch-based devices, smartphone apps, key rings and pendants. These are generally used when there is a particular risk of the person getting lost or going missing. The location of the person carrying the device can be viewed on a computer, tablet device or mobile phone. Many tracking devices also allow the person to press a panic button if they get lost.

Many new mobile phones also have location finder technology. This could be considered instead of a stand-alone tracking device. When purchasing a device to enable safer walking, it is important to consider how reliable it is. For example, will it work when the person is indoors, and how often will it need charging?

The signal required for tracking devices to work can be patchy, which means the device may not work in all areas. Some of the devices can be difficult to use (especially for a person with dementia) and the person may not want to wear a device or risk forgetting that they should have the device with them. The person with dementia may also not be able to respond appropriately when an alert happens (for example being told to stay where they are). Safer walking technology can enable some people with dementia to have greater freedom and independence, and can ultimately reduce the use of unpleasant solutions such as drugs and physical restraints. It may also mean that carers worry less about the person’s safety. The use of safer walking technology has many possible benefits, but it also raises important ethical questions around capacity and consent.


Telecare usually refers to a system or devices that remotely monitor people living in their own home, enabling them to access support or response services when necessary. The various pieces of technology are connected via a telephone line or over the internet. Telecare systems can include community alarms, sensors and movement detectors, and video conferencing.

Telecare systems are often used to support independence and personal safety. They may help to reduce the risks associated with living alone, and can be useful for people living with dementia. Telecare can provide assistance to the person to help them to do things (such as a phone call to remind them to take their medication). It can also alert others of dangerous situations (for example if they were to have a fall or leave the gas on). Sensors around the home can be linked to a nominated person or call centre. The system monitors a person’s activities and can trigger an alarm to the person or call centre if a problem occurs. The alarm can also be triggered by a person pressing a panic button or community alarm.

Telecare has traditionally been provided by a community alarm or monitoring service provided through social services. However, it is now possible to set it up privately.

Telecare comes in various forms and may be used for a range of situations:

Community alarm – This is a pendant worn by the person that they press if they become worried or if there is an incident (for example if they have a fall). The person will need to remember to wear the pendant.

Medication reminders – An automatic pill dispenser can be linked to a call centre. If the medication isn’t taken at a set time, an alert is raised and the person is contacted to remind them to take their medication.

Floods – Sensors can be fitted on skirting boards or floors in the kitchen or bathroom. If taps have been left running and cause a flood, the system will shut off the water and raise the alarm.

Extreme temperatures – Sensors will send a warning signal if the temperature is very low, very high, or changes suddenly. This can be useful in the kitchen – for example, to detect a pan that has boiled dry. It can also detect if the temperature in a room is low enough to pose a risk of hypothermia.

Absence from a bed or chair – A sensor is placed on a bed or chair. If a person gets up and doesn’t return within a pre-set time, or if they don’t get up in the morning, an alarm is raised.

Getting up in the night – Sensors placed by the bed can be used to activate an alarm when the person gets up in the night – for example, to alert someone to help them get to the toilet. Similarly, lights with movement sensors can switch on if a person gets out of bed or enters a room.

Leaving the home – A system may be set up to trigger a response if the front door is opened, perhaps during specified times (for example at night), or if a person does not return within a specified time.

Devices to monitor daily activity – These are unobtrusive movement sensors that can oversee  a person’s activity in their home over a period of time. They can sometimes help relatives or community services get a better idea of a person’s activity during the day and night. This can allay fears that the person with dementia is not coping well, and may help others to step back and not become too closely involved. Alternatively, it may show that the person needs more assistanceand can be used to start discussions about the type of support that may help. An alert can easily be set to tell the person monitoring if something unexpected happens, such as a visitor at an odd time or the person leaving their home in the middle of the night.

More information on what is available in the person’s local area will be available from their local authority, local assisted living centre, or by searching online.

Telecare systems - what are the ethical considerations?

As with tracking devices, using telecare systems poses ethical challenges.

Devices to support engagement, social participation and leisure

While assistive technology has traditionally been used to help people with dementia remain safe and continue with everyday activities, it is increasingly being used to support a person’s social life and provide opportunities for activities and enjoyment. This can help them to maintain their relationships, skills and wellbeing.

With the increasing availability of tablets, smartphones and apps, there are many new options to help people stay in touch and engage with those close to them. They also offer opportunities for activities, which is important for supporting thewellbeing of a person with dementia. These can include reminiscence, creative activities (such as music), video calling and life story work.

Other types of assistive technology that can be used for leisure include:

  • digital photoframes – these can be programmed to show a slide show of photographs and may help support conversation with others
  • puzzles and games
  • sensory stimulation – devices that use touch, sound and light (such as a sensory cushion)
  • electronic games and apps (such as a video-sharing app to support discussion about the past)
  • mental stimulation (such as ‘brain training’ devices)
  • easy to use equipment (such as music players and radios).

A tablet used to deliver these can itself become a topic of conversation, and so lead to more interactions for the person. This is particularly true for ‘intergenerational’ interactions, where the shared experience of the technology gives a younger person a connection that might otherwise not have existed.
