i often feel scared when i am out walking or running alone. so when i saw that apple watches were being used to detect heart—attacks, i had a kind of lightbulb moment and i thought, maybe this could be applied to women's safety? but as the team have discovered, it is difficult to simulate distress. we looked at loads and loads of police reports and loads and loads of cctv footage of people being attacked and we tried to find things that were common amongst everything, and we saw the struggling motion the pushing motion, that kind of change from being very regular and repetitive to something that was erratic. so they created a test which allowed them to collect the data to train an algorithm which could recognise similar events. 26 plus 58. this smartwatch tech is an early development, but if the team managed to crack it, it could be something we see being used by women in the future.
