Provided are methods, systems, and devices for activating components of a computing device based on a mode associated with the state of objects including a computing device. Sensor data based sensor outputs from one or more sensors that detect one or more objects can be received. Based in part on the sensor data, the state of the one or more objects can be determined. The state of the one or more objects can include one or more spatial relations of the one or more objects with respect to a computing system. When the state of the one or more objects satisfies one or more operational criteria, a mode associated with activating a component of the computing system can be activated. The component can include a microphone component, a camera component, or a text input component. The component can be associated with performing including input detection.
