RealWear Explorer offers a host of essential tools to make developing on HMT an easier experience including:

  • Install APKs onto HMT by drag-and-dropping from the PC or Mac
  • One-click snapshots of the HMT screen
  • Quick access to ADB command line

Explorer-UI
 

The main part of the RealWear Explorer window is used to mirror the contents of the HMT screen. The screen will continuously refresh at a rate of two times per second to show faithfully what the user would see when wearing the headset.

Furthermore, clicking anywhere on the screen can be used to activate the HMT user interface elements – for example clicking the “My Apps” button has the same effect as speaking “My Apps” inside the headset.

Likewise, the computer keyboard can be used to type into text fields on the HMT user interface. In this way the developer can view and interact with the HMT application without having to continually wear the device.

adb-1

 

The “ADB” option opens up a new command prompt window, allowing for Android adb commands to be entered and run.

RealWear Explorer allows you to install APKs (Android applications) on the HMT, also known as “side-loading”. To side-load an app to your HMT, drag an APK file from the computer desktop onto the “drop zone” of RealWear Explorer.

  • Drag-and-drop APK file from desktop onto the “drop zone”.
  • RealWear Explorer will install the APK and report progress.
  • On completion a message will be displayed to indicate success or failure.

RealWear Cast

connectwithcast

RealWear Cast provides a faster way of mirroring the screen from your HMT and allows you to connect to your HMT wirelessly.

By default RealWear Explorer mirrors the screen using ADB over USB. When mirroring the screen in this mode there is a cap of 2 frames per second which may be too slow for some users.

RealWear Cast can work wirelessly over WiFi, or wired over USB. When connected using RealWear Cast it is possible to stream at up to 30 frames per seconds.

To use RealWear Cast over USB:

  • Connect the HMT to RealWear Explorer using a USB cable to begin streaming at 2 FPS.
    • If the latest RealWear Cast app is installed on your HMT faster streaming will begin automatically.
    • If RealWear Cast app is out of date RealWear Explorer will help you to update it. Once updated, faster streaming will start automatically.
    • If RealWear Explorer isn’t installed RealWear Explorer will help you to install it. Once installed, faster streaming will start automatically.

To use RealWear Cast over WiFi:

  • Ensure that the HMT and the computer are on the same subnet.
  • Connect the HMT to RealWear Explorer using a USB cable to begin streaming over USB.
  • If streaming using RealWear Cast over USB begins automatically, select the “Disconnect from RealWear Cast” button.
  • Select the “Connect using RealWear Cast” button again, which will connect wirelessly rather than over usb.
  • Follow the instructions on the wizard to pair your HMT with RealWear Explorer.
  • Accept any prompts on the HMT to allow RealWear Explorer to capture the screen.
  • RealWear Cast will begin streaming wirelessly automatically. It is now safe to disconnect the USB cable without interrupting the stream.

RealWear Explorer will also remember your paired HMT. When RealWear Explorer is not connected to any HMT the last 5 paired devices will be listed. Select the device you would like to view and RealWear Explorer will begin streaming.

RealWear Explorer Configuration Options

options

RealWear Explorer has a limited number of configuration options that can be accessed by selecting the options button.

settings

This will display an Options Panel, allowing the following settings to be made:

  • ADB File Location: By default, RealWear Explorer ships with its own copy of the ADB executable. However, this option allows different versions of ADB to be specified.
  • Editor File Location: The Editor is the system text editor used to open and read the “logcat” files from HMT. This option allows the user to specify a different text editor to use.
  • Toggle Sound: Enables or disables sounds in RealWear Explorer.
  • RealWear Cast FPS: This allows you to choose the maximum frames per second that RealWear Cast will use when streaming. A higher value will use more processing power but will result with a smoother stream, a lower value will use less power but the steam will be jerkier.
  • Never ask to install RealWear Cast: When enabled, this setting will stop RealWear Explorer from prompting to install RealWear Cast when the HMT is connected to your computer.

Presentation Mode

Presentation Mode allows RealWear Explorer to be run in full screen. This provides a way to present HMT functionality in a distraction free way.

All RealWear Explorer functions still are available when in presentation mode.

To exit presentation mode use the escape key on your keyboard.
