![]() Delirious patients often don’t know where they are, what time it is or what’s happening to them. This isn’t a situation where you can assess the patient’s pain by asking “is your arm still painful today?”. So we want to be able to assess and address that pain, but to do so accurately you need an idea of what and where that pain is, and the intensity. When your patient can’t engage with this then things become very difficult, and pain has such a knock-on effect on the patient’s comfort, mood, even the extent of their delirium. Lilian Stolk: Why is facial recognition technology so suitable to research a possible link between pain and delirium?Įmily West: There has always been a drive to be able to assess pain in a somewhat objective way, but many scales that we currently use rely on self-report. To better understand the potential use of facial recognition technology in healthcare, I asked Emily some further questions. They are looking at the “noise” that the hospital setting brings, and seeing if that affects how Painchek works. ![]() In Emily’s research project, Painchek is used to look at the pain and discomfort by people that are hospitalised for dementia. Research shows that the tool scores high in accuracy, sensitivity, and specificity. It uses the smartphone camera to record a short video, and analyses facial muscle movements that indicate pain. The tool Emily and her team uses, Painchek, is already in use by several Australian elderly care institutions. In her case, those patients are people with dementia. She is currently trialling a facial recognition tool that recognises pain in patients that are unable to verbalise their pain themselves. Multidisciplinary researcher and artist Emily West may have an answer. Can the technology bring something good to humanity, without taking our freedoms away? To make it possible to find missing persons with the help of facial recognition technology, we always have to be followed by CCTV cameras on the street. You might wonder if that risk is worth giving your face away to a tech giant like Facebook. ![]() Facebook wants to scan our faces under the guise that they will use that information to prevent photos of us circulating on the platform without us knowing. These technologies are always sold to us with the promise that they will make our lives better, but often the disadvantages outweigh the benefits. In this dossier we’ve highlighted the risks and focused on the scary side of facial recognition technologies, but it’s also interesting to shed a light on their possibilities.
