Virtual entry assistant using automated greeter
摘要:
A virtual security guard or receptionist automatically allows entry to an area by determining a user's identity and comparing that to an access list. If the user is authorized, then the user is allowed entry to the area. The receptionist can be implemented by either a sign, or by using a virtual receptionist to shows a picture selected from a media server that has many different pictures. Computer intelligence can be used to allow the receptionist to carry out almost any operation that is carried out by a real receptionist.
