Use a Session and attached Stream to receive frames and capture photos.
Key concepts
- Session: Device connection lifecycle created through
Wearables.createSession(...) - Stream: Camera stream accessed via
camera.streamafter attaching the camera withsession.addCamera(...) - StreamConfiguration: Resolution and frame rate configuration for the stream
- PhotoData: Still image captured from glasses while streaming
Create a session and attach a stream

val session = Wearables.createSession(AutoDeviceSelector()).getOrElse { error ->
throw IllegalStateException(error.description)

session.start()
val camera: Camera = session.addCamera(
StreamConfiguration(
videoQuality = VideoQuality.MEDIUM,
frameRate = 24,
),
).getOrElse { error ->
throw IllegalStateException(error.description)
}
camera.stream.start().getOrElse { error ->
throw IllegalStateException(error.description)
}
Resolution options
| Quality | Size |
|---------|------|
| VideoQuality.HIGH | 720 x 1280 |
| VideoQuality.MEDIUM | 504 x 896 |
| VideoQuality.LOW | 360 x 640 |
Frame rate options
Valid values: 2, 7, 15, 24, 30 FPS.
Lower resolution and frame rate usually produce better visual quality per frame over Bluetooth.
Observe stream state
StreamState transitions: STOPPED -> STARTING -> STARTED -> STREAMING -> STOPPING -> STOPPED -> CLOSED
lifecycleScope.launch {
camera.stream.state.collect { state ->
when (state) {
StreamState.STREAMING -> {
// Frames are flowing
}
StreamState.STOPPED -> {
// Streaming ended
}
StreamState.CLOSED -> {
// Stream fully closed
}
else -> Unit
}
}
}
Receive frames
lifecycleScope.launch {
camera.stream.videoStream.collect { frame ->
updatePreview(frame)
}
}
Capture a photo
lifecycleScope.launch {
camera.stream.capturePhoto()
.onSuccess { photoData ->
val imageBytes = photoData.data
savePhoto(imageBytes)
}
.onFailure { error, _ ->
showCaptureError(error.description)
}
}
Clean up
Stop the stream when you no longer need camera data, then stop the parent session if the device interaction is finished.
camera.stop()
session.stop()
If you want to remove the capability entirely before re-adding it, call session.removeCamera().

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
Microscopy data management platform. Access images via Python, retrieve datasets, analyze pixels, manage ROIs/annotations, batch processing, for high-content screening and microscopy workflows.
Python library for working with DICOM (Digital Imaging and Communications in Medicine) files. Use this skill when reading, writing, or modifying medical imaging data in DICOM format, extracting pixel data from medical images (CT, MRI, X-ray, ultrasound), anonymizing DICOM files, working with DICOM metadata and tags, converting DICOM images to other formats, handling compressed DICOM data, or processing medical imaging datasets. Applies to tasks involving medical image analysis, PACS systems, radiology workflows, and healthcare imaging applications.
This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.
