Application: Human Computer Interface
Description
A human-computer interface (HCI) is the point of interaction between humans and computers, enabling users to communicate and control digital systems effectively. Advances in HCI include natural language processing, brain-computer interfaces, and immersive technologies like augmented and virtual reality, which aim to make interactions more seamless and human-centric. Example scenarios include:
- Information dissemination: Airports, stadiums, hotel lobbies, receptions
- Healthcare: Medication transport, patient care, companionship, surgery
- Industry: Manufacturing automation and warehouse
- Public safety: Surveillance, policing, disaster recovery
