Next generation Kinect is as small as a stick of gum

The next generation Kinect, code-named Capri, is 1/10th the size of the current Kinect and is as small as a stick of gum.

Capri size of a stick of gum

It has a range of 0.8m to 3.5m letting you control your smartphone or tablet with a wave of the hand or scan a room in 3D (and possibly even record movies in 3D).  PrimeSense is planning on releasing it at the end of the year and it should be in phones and tablets next year.

PhoneGap is a free open-source plugin for Eclipse that lets you write Android and iPhone apps in html/javascript (it even has jQuery-like UI plugins). As of version 0.9.1 it’s still very rough and it was a real pain to install and compile projects. Hopefully you won’t have to go through the same pain I did, so I updated the phonegap getting-started wiki with these notes:

Make sure android sdk and ant are not installed in directories that have a space in the name (i.e. do not install in c:\Program Files).

After installing java jdk (NOT the jre), eclipse, android sdk (following all their directions and getting a helloworld app working), rubyinstall, ant, and phonegap, make sure you have these environment variables set up:
WINDOWS: (Right-click My Computer (or Computer), Properties, Advanced tab, Environment Variables button)
• ANDROID_HOME (for example: C:/android-sdk-windows)
• ANT_HOME (for example: C:\apache-ant-1.8.1)
• JAVA_HOME (for example: C:\Program Files\Java\jdk1.6.0_20)
• Path = (includes these) (for example: C:\Ruby191\bin; C:\apache-ant-1.8.1\bin; C:\Program Files\Java\jdk1.6.0_20\bin; C:\android-sdk-windows\tools)

Once you have all that set up, you’ll start to have meaningful errors when you try to build the example phonegap project.

Random notes:
• The droidgap script in your phonegap folder is set to target_id 8, but you need to run “android.bat list targets” from your phonegap folder to get your list of target_ids for each platform you have installed. For example if I only have 1.6 and 2.2, then the target_id in the droidgap script for 1.6 would be set to “1” and 2.2 would be “2”.
• In the build command, the package name can not be just the app name, you’ll need to add “com.” or something to make the phonegap compiler happy (i.e. “example” “com.example”).
