We will be now exploring applications involving

- Medical Imaging
- Computer Vision
- Medical Records
First, the Unboxing
Account Set Up
One of the Glass devices has been attached to the account
and its associated
and tested it by capturing and sharing simple videos.
In order to start developing applications for the Glass,
we installed in an Ubuntu Linux 12.10 the software development kit
Glass Development Kit
that in turns requires the
This is how the configuration looks like, when using Eclipse as an IDE.
Beginners Set up
We followed the set up for beginners:
and verified it by writing a first simple app for the Nexus 7 tablet
This required to select a specific version of the SDK, that in this case turned out to be
Minimum version SDK - API 15
and to put the tablet in developer mode, using the Geek-loving cryptic method:
"On Android 4.2 and newer,
Developer options is hidden by default.
To make it available, go to Settings > About phone
and tap Build number seven times."
This is how the devices are presented when the Glass is paired via Bluetooth with the
Nexus 7 tablet, and the tablet itself if connected to the laptop via the USB cable.
The Glass itself must also be set up in Debug mode, in order to upload apps to it.
We did that by getting into the Settings Menu in the Glass.
We then tested the basic examples for the Glass
and verified that we could upload them from the Laptop, using Eclipse,
into the Glass device, via a direct USB connection.
Design for Glass
The following are the design guidelines for Glass applications:
Modifying an Example
To bootstrap an example, we visited the Google Glass organization in Github.
and cloned the Compass example:
then imported into Eclipse, using the options
File -> New -> Project -> Android Project from Existing Code
and then browsing to the directory where we cloned the Git repository.
Verified that the application could be run in the Glass.
Time to Edit
We then forked the Compass sample repository in Github
Import it as a project in the Eclipse environment
The set up:
- Screen casting from the Glass into a Nexus 7 tablet
- Uploading code into the Glass from the Ubuntu Linux Laptop via USB cable
The application running after disconnecting the USB cable, still screencasting into the tablet.
Here is the screenshot of the resulting application, taken from the Glass.
Knowing how to force the Glass to turn off, is helpful as we debug code :-)
The process of uploading code, tends to heat up the Glass quite a bit.
At intervals we had to take breaks to let the Glass cool down.
What to do Next
The task that we will be trying next, is to get inspiration from the
to build an initial application that use the min3D library to render simple graphics.
We will be sharing the progress in this exploration soon.
