New emotion reading technology claims to stop agitated criminals and potential terrorists on the street before they act. A firm has created software that can be embedded in CCTV cameras to track the age, gender, emotional state and identity of people and keep track of suspicious behaviour. If someone is feeling particularly stressed or angry the algorithms will flag it up with authorities who could intervene before anything happens. The company claims it can track the emotional state of a person from CCTV with more than 94 per cent accuracy.
