New development of smart carpet and its applications

A floor sensor system was set up to detect gait activities by recording the amount of pressure applied in different places when someone walks across it.

Fans of Tom Cruise may recall vividly in his movie Mission: Impossible (1996), Tom intruded to a room of cyber look through the ceiling. He was hovered just inches above the floor to gain access to a computer, being very careful not to touch the floor. 

Two decades later, we have smart carpet that would make Tom Cruise and his partners even more difficult to get their jobs done.

Smart carpet is generally referred to the floor finishes with embedded electronic devices that enable detection of movements that exert upon it. It is used for monitoring activities of elderly especially those who live alone.

Alongside the development of new behaviour biometric, smart carpet now becomes even more versatile. 

Research team at the University of Manchester

The prominent case here is the research team led by Prof. Krikor OZANYAN and Dr Patricia SCULLY at the University of Manchester. They adopted efficient machine learning methodology to classify gait data from raw tomography sensor data accurately without the need to reconstruct images.

A floor sensor system was set up to detect gait activities by recording the amount of pressure applied in different places when someone walks across it. The team did not use piezoelectric wires or pressure sensors / tiles as other researchers used to be. They used low cost standard polymer optical fibre that form grids to transmit and receive lights.

By using artificial intelligence, the changes in location and amount of lights as caused by human motions, e.g. walking or exercising, are recorded, plotted and analyzed. The complexity of the research lies not only on identifying the types of footstep patterns but also in the necessity to cope with the footstep spatial and temporal variances in the data captured from a real-world gait recording system.

The result was encouraging with high accuracy in identifying pre-defined variants of gait. 

Possible uses of smart carpet

The applications of magic carpet can be group into 2 categories: health and safety; and security. It can be installed to monitor old people’s movements in elderly home, as well as patients in clinics and hospitals, and thus becomes an integral part of the healthcare systems.

For security purpose, such a carpet can be placed to track and identify people who walked past on it at residential and office buildings. They can also be applied in areas where volume of people is high and constant surveillance is required to ensure public safety. These places include transport terminals (e.g. train stations and airports), museums, government premises, tourist attractions and places for entertainment and leisure.

… by leveraging machine learning, organizations can largely diminish the security concerns that come with Internet of Things (IoT). Machine learning enables data exchanges to be monitored within the organization, and with external parties to detect anomalies that are not considered the norm. Machine learning can also aid in predicting threats, in its ability to analyze historical data from specific trends, which can be evaluated from the big data produced by the algorithms.

MIT using radio waves to monitor patients’ health through walls

 

A professor at the Massachusetts Institute of Technology has developed a device that can monitor your health using radio signals and machine learning, even through walls.

The gadget looks like a box and works like a Wi-Fi router; the low-power wireless signals reflect off nearby people’s bodies and carry information back to the box, the MIT tech review said. The box analyzes the information and offers up health data. The device senses your movements, even if you’re just breathing, by recording changes in the electromagnetic field around you.

Smart elderly home

Recent IT developments for elderly home

Alongside the growing ageing population, the governments around the globe have been investing in IT to provide smart home for the elderly. The major reason behind perhaps is to alleviate the medical and healthcare burden arising from the increasing average life expectancy.

The design priority of smart home for the elderly, especially for those who live alone, should be in the following order: safety > health > general wellbeing.

Internet-of-Things (IoT)

Smart elderly home usually comes with the concept of Internet-of-Things (IoT). IoT is the network of physical devices, e.g. electrical appliances, sensors and personal computers, embedded with software and electronics. Such a network enables integration and automation with speedy connectivity and exchange of data among the devices. With the advancement of internet and high-speed cellular network technologies, IoT is also connected to outside systems, e.g. hospital or healthcare systems, for performing safety and health monitoring and emergency purpose.

The networks that enable smart elderly home are normally

  • Personal Area Network (PAN) or Wireless Sensor Network (WSN) for general sensors
  • Wireless Body Area Network (WBAN) or Body Sensor Network (BSN) for biomedical sensors

Upon completion of analyzing data collected on the environment, as well as users’ activity and physiological conditions, the central unit of a system responds by activating relevant appliances, e.g. air-conditioning, and/or sending signals to the caregivers in healthcare centres or hospitals via the internet or mobile network.

Safety

One example of safety measures is the Smart Elderly Monitoring and Alert System in the Singapore’s public housing, developed by Astralink Technology, a Singaporean company with innovative products featuring voice, data and video. The system is installed in the one-room rental apartments for senior citizens. It makes use of motion sensors and cameras to monitor the living patterns of the elderly, and alert the caregivers and family members via an app if there is any anomalies, based on the cloud analytics with the elderly profiles.

Apart from Astralink Technology, Sensor City is another company deploying infrared sensors to monitor the safety of the aged by anonymously tracking their movements.

Health and general wellbeing

Home automation is one of the main features in elderly home to enhance the residents’ health and general comfort and convenience. Common IT facilities cover

  • security system
  • door locks
  • video door phone system, e.g. Nest Hello
  • lighting control
  • air-conditioning control
  • curtain control
  • automated furniture (beds, chairs, dining table and wardrobe, etc.) for both health monitoring and wellbeing
  • fridge, e.g. Samsung Family Hub Refrigerator

Meanwhile, machine-speaking personal assistants, e.g. Google Home and Amazon Echo, are being adopted to integrate individual systems and gadgets.

Furthermore, short range communication technology is deployed. For instance, old people including those who are susceptible to losing their ways are monitored through wearable electronics using radio frequency identification (RFID). The use of RFID can also be extended to recording use of community facilities, assisting the elderly to read out texts, and conducting health training through interactive media.

For longer distance monitoring, Global Positioning System (GPS) tagging system is used. For example, Mindme Locate uses satellites to find out the users’ location accurately. 

Emerging technologies

  • Smart carpet – it is a carpet with pressure points sensor underneath to detect the presence of people. For the elderly, in case they fell down or behaving abnormally, alerts will be sent to the monitoring centre who can come their rescue.

  • Smart Mirror – a prominent example is Wize Mirror which gives the user a check-up each time when he/she stands in front of the mirror. It has built in 3D-scanners, multispectral cameras and gas sensоrs which help tо identify early signs оf seriоus illnesses. The analysis оf the human face (facial expressiоns, skin tоne and fatty tissue cоntent) also helps tо indicate the initial diagnоsis.

  • Smart contact lens – a technology developed by Goolge X in partnership with Novartis, a Swiss multinational pharmaceutical giant. The lens contains a tiny and ultra slim microchip that is embedded in one of its thin concave sides. It aims to offer an easier and more comprehensive way of monitoring the glucose levels of diabetics.
