SHORT ANSWER
AI-pet sensors measure signals, not feelings or intentions. Touch pads detect contact, microphones capture sound, cameras provide pixels, and motion sensors estimate movement. Software combines those signals into uncertain interpretations that should remain bounded and explainable.
Touch and proximity
Capacitive pads, force sensors, bump switches, and distance sensors can distinguish a pat from a collision or detect that someone is nearby. Placement and calibration determine whether interactions feel responsive.
Sound and speech
Microphones can detect volume, direction, wake words, or speech. Background noise, accents, children’s voices, and multiple speakers remain difficult. Products should signal clearly when audio is active.
Vision and motion
Cameras can support navigation, face or object recognition, and gesture input. Accelerometers, gyroscopes, encoders, and joint sensors tell a robot how it is moving. Each sensor adds failure cases as well as capability.
Sensor fusion and uncertainty
Combining signals can reduce ambiguity, but no combination makes inference perfect. Safe systems avoid pretending they know more than the measurements support and provide hardware or software privacy controls.
