Excellent article from Australia's only eHealth and Health IT Magazine looking at the latest developments in Sensor Alarms. Traditionally an expensive and cumbersome affair motion sensing has been the subject of some criticism for it's acceptability and reliability in use. Auto-ID Lab in association with the Adelaide Geriatrics Training and Research with Aged Care (G-TRAC) Centre hope to minimise these problems and "are developing a system using very low-cost, wearable sensors allied to a customisable alarm system based on individual falls risk, along with a more intuitive, discreet alarm system that can be integrated with common nurse call systems".
What is so interesting about these sensors is the size:
“Traditionally, if you look at algorithms that are in practice in terms of deciding whether a person is on or off the bed, they are almost all pressure mat-based,” Dr Ranasinghe said. “If the pressure is below [a certain level] or above it, you are in or out of bed. We have a different approach … we train the computer to recognise patterns and the computer can learn what the person is doing based on these patterns.”
