# Smart Versus Not-Smart Devices

Comparing ordinary objects with devices that have computer features, such as answering spoken questions. Sensors detect things and trigger responses, but sensing or using electricity alone does not prove that a device has smart computer features.

## Ready when they can

- Compare described objects and identify a stated computer feature
- Explain how a smart speaker responding to spoken questions differs from a regular radio
- Identify what a movement sensor detects and how an automatic door or light responds

## Lesson: What makes a device 'smart'?

You have met computers inside everyday devices. People call some devices 'smart' because of their computer features. A smart speaker uses a computer to work with a spoken question and give a reply. 'Smart' does not mean it thinks or feels like a person.

**Example.** A regular radio plays broadcasts. Its controls change the station or volume. It does not answer spoken questions. A smart speaker can answer spoken questions. A smartwatch can use information about your movement to count steps.

*(drawing: The computer works with your question to give a reply.)*

A sensor detects something. A movement sensor detects movement. A door can respond by opening when someone approaches. A motion-sensor light can respond by turning on. Movement is what the sensor detects. Opening or lighting up is the response.

Electricity and movement alone do not prove that a device is smart. A fridge light may use a door switch with no computer. A toaster may sense heat. Check whether it has computer features and what they do.

**Recap.** Check whether a device has computer features. A sensor detects something; the device then responds. Electricity or movement alone is not proof.
