| Basic Definition | Eyewear with an integrated image sensor that can capture still photos or record video from the wearer’s viewpoint. | A broad category of connected eyewear that may provide audio, notifications, sensors, displays, or other digital functions. A camera is not required. |
| Primary Function | Hands-free visual capture, first-person recording, visual documentation, and sometimes live sharing. | Hands-free access to information, communication, audio playback, navigation assistance, activity sensing, or device control. |
| Camera Capability | Usually includes a front-facing camera, with image quality, field of view, stabilization, and recording limits varying by model. | May include a camera, but many designs rely only on microphones, speakers, motion sensors, touch controls, or a small display. |
| Typical User Interaction | Photo or video capture may be started with a physical button, touch control, voice command, or an accompanying mobile application. | Interaction commonly uses voice commands, touch gestures, buttons, head movement, a phone application, or visual controls. |
| Output and Feedback | Captured media is generally stored on internal memory or transferred to a paired device. Some models provide audio or visual confirmation during recording. | Feedback may include audio through open-ear speakers, notifications, visual overlays, indicator lights, or information shown on a connected device. |
| Display Requirement | A display is optional. Camera glasses can record without showing information in the wearer’s field of view. | A display is also optional. Some smart glasses provide a heads-up display, while others offer audio-only functions. |
| Privacy Considerations | Higher privacy sensitivity because people nearby may be recorded without realizing it. Visible recording indicators, consent practices, and local laws are important. | Privacy concerns depend on the sensors included. Microphones, location services, biometric sensors, and cameras can each create different risks. |
| Connectivity | Often connects to a smartphone through Bluetooth or Wi-Fi for media transfer, remote control, software updates, or cloud features. | May connect through Bluetooth, Wi-Fi, cellular connectivity, or a companion device, depending on the available functions. |
| Battery Demand | Recording video generally consumes more power than passive audio or basic sensor functions, so continuous recording can shorten operating time. | Battery life varies widely. Audio playback, active displays, wireless communication, cameras, and frequent sensor use usually increase power consumption. |
| Storage Requirements | Requires local storage, phone storage, cloud storage, or a combination of these to save photos and video files. | Storage needs are usually lower when the glasses only stream audio, display notifications, or relay sensor data. |
| Best-Suited Activities | Hands-free documentation, short-form personal recording, outdoor activities, demonstrations, inspections, and accessibility-related visual assistance. | Calls, music, navigation prompts, notifications, translation support, activity tracking, accessibility assistance, and hands-free device control. |
| Key Limitation | Video quality can be affected by movement, lighting, lens position, battery capacity, storage limits, and restrictions on recording in private or protected locations. | Functionality can be limited by battery life, phone dependence, network coverage, comfort, compatibility, limited display space, or the absence of a camera. |
