Guides

The SmartEyeglass API allows you to control what is displayed on the device, and to access and control the device sensors, such as the accelerometer, compass, camera, microphone, and so on. In this section, you’ll find a number of different guides talking you through the depths of SmartEyeglass development.

  • Registration
    Every extension must provide basic configuration information about the app and its capabilities to the Smart Extensions framework.
  • User interface
    This guide shows specific techniques for defining an application UI for the SmartEyeglass display. You can render bitmaps or XML-based layouts, handle user-interaction events, and customize transitions between screens in your UI with built-in animation effects.
  • Widgets
    Define a widget that is suited to the SmartEyeglass display and use it as the entry-point card for your app.

  • Sensor data
    You can access data collected by the various sensors. SmartEyeglass has an accelerometer, a magnetic field sensor, and a gyroscope (a rotation vector sensor) that provide information about the user’s head movement, attitude, and direction. A light sensor provides information about ambient brightness.

  • Camera
    The SmartEyeglass built-in camera can record still pictures or video, or it can save a real-time JPG stream to memory.
  • AR rendering
    Learn how to overlay a dynamic display onto real-world objects as they appear in the view the user sees through the SmartEyeglass.
  • Voice-to-text input
    SmartEyeglass can receive voice input from the built-in microphone, and translate voice into text.

  • Audio I/O
    The SmartEyeglass device acts as a Bluetooth headset. You can use the Android Bluetooth Hands-Free Profile (BT HFP) API to capture sound and play back audio as you would for any standard Bluetooth headset.
  • Settings guide
    Utility methods allow you to control settings such as safe display mode, whether the connection is Bluetooth or WiFi, and whether to play a sound on the controller’s speaker in response to particular events.
