LpGlass and Head Tracking Revisited

We had the opportunity to try out one of the new augmented reality glasses AiRScouter produced by the Japanese company Brother. We first tried one at a Brother product exhibition here in Tokyo. Although the glasses are a little heavier than normal glasses, they fit quite well and the overlay image is well visible.


We experimented with the glasses a bit and set-up a prototype application for augmented reality using our LPMS-B sensor for head tracking, codename: LpGlass. The video below shows a demo of our LPMS-B IMU attached to the AiRScouter.

Similar to the Google glasses there seem to be a huge number of applications, especially for augmenting task environments for medical procedures, industrial assembly, education etc.

LPMS-B on Android

Here is a first demo of the Android driver of our LPMS-B inertial measurement unit. The LPMS-B is controlling the orientation of a simple 3D cube on the screen of a Samsung Galaxy Tab 10.1. Improvements that are soon to be completed are faster response times and enhanced GUI functionality for calibration.

Case Prototypes

Finally we are ready to show somw progress of the sensor development. Below you can see the new design and a few designs of the case of the Bluetooth version of the sensor (LPMS-B). Actually these have been ready for quite some time, but we were just to busy with finishing the firmware etc. to show them around.

For this image we made half of the case transparent, so you can see the sensor mainboard and the battery inside. Using this larger battery, the size of the sensor has become bigger than the initial prototypes, but the continuous runtime is up to 10 hours. We are planning on producing differently sized cases for different applications, requiring different battery runtimes.

Please note that this 3D print here does not show the final material that we are going to use for the case. The final version will probably be blue and made of non-transparent or semi-transparent plastic.
