PEAS Representation

• PEAS is a model on which an AI agent works upon.
• Properties of an AI agent or rational agent can be grouped under the PEAS representation model.
• This specifies the setting for intelligent agent design.

• PEAS Representation stands for:

  • P - Performance Measure
  • E - Environment
  • A - Actuators
  • S - Sensors

Performance Measure -

• It is the unit function to judge the performance or success of the agent's behavior.

Environment -

• It is the real environment, surrounding, or atmosphere where the agent needs to perform activities.
• It keeps changing with time if the agent is in motion activities.

Actuators -

• These are the instruments, equipment, or organs using which the agent performs activities in the environment.
• It acts as a delivering part or output activity of the agent towards the environment.

Sensors -

• These are instruments, equipment, or organs using which agent captures the state or instances of the environment.
• It acts as a receptive part or input for the agent.

PEAS Representation of a Biometric Attendance System

Performance Measure

• Storage Capacity - Biometric attendance system can store and verify a large number of users' data.
• Scanning Time - How much time does the system take to scan or sense the user data like fingerprints or recognize the face.
• Verification Time - The success of a biometric attendance system depends highly on the time taken for the identification by the biometric machine.
• Durability - Biometric machine should be rugged, durable, and can work in extreme temperatures.
• Flexibility - Biometric attendance system should be easy-to-install and easy-to-use,
• Internet Connectivity - It is mandatory to keep the system working without bugs and keep track of clock-in and clock-out time for the users.
• Power Consumption - The system should use less power.

Environment

• There are multiple environments or surrounding areas where Biometric attendance system can be applicable such as
  • Banks
  • School and Colleges
  • Offices
  • Hospitals

Actuators

• Static Indicators - It shows bright green color when the user is verified if not then show bright red color.
• Database Storage - It holds all the data about all the users who check in, check out at what timings, when present, and when not.

Sensors

• Image Capture Surface - It captures things like fingerprints, and palm.
• Hand Geometry Sensors - It recognizes various things such as palm-width, finger-length, finger-width, finger-area, and finger-thickness.
• Optical Sensor - It works by focusing light on your fingerprint, palm, face, and retina to capture a digital image.
