Converting classes with the Parcelable protocol 5 Jul 2013 | 12:21 am
Many good tutorials can be found about the Parcelable protocol in Android. If the Android framework has to serialize a set of values (either for AIDL-based IPC or for Intent-based message passing), it...
Tap detection supported by the gyroscope 21 Jun 2013 | 01:02 am
Once upon a time I made a Londroid presentation that briefly mentioned the possibility of detecting taps on the phone's body with an accelerometer (it is in slide 31). You may rightly ask, why do you ...
Advantages and limitations of PhoneGap for sensor processing 29 Apr 2013 | 12:58 am
This is my Droidcon Tunis 2013 presentation about the effect of the web application model on battery consumption. Test programs related to the slideset are available here. You have to be logged into ...
Data capture application for car speed, accelerometer, compass and gyro fusion experiments 11 Mar 2013 | 01:07 pm
In my previous post I wrote about my enthusiasm of integrating car sensors with the mobile device's own sensors. The first step was to implement a data capture application that saves sensor data into ...
Call for papers for Droidcon Tunis 2013 2 Mar 2013 | 03:42 am
Last year I had a presentation at Droidcon Tunis. The conference was inspiring with a clever and enthusiastic audience and the presentation became a success with over 16000 views since the end of the ...
Car sensors 23 Feb 2013 | 03:06 am
My conclusion from the speed bump post was that the built-in accelerometer in the Android phone is probably not enough to detect the obstacle. Alexander Kosenkov commented that maybe the accelerometer...
Detecting speed bumps with accelerometer 20 Feb 2013 | 02:43 am
Somebody came in from the internet some months ago and asked whether speed bumps (also called sleeping policemen) can be detected with an Android phone. You know, speed bumps like this: I was cautiou...
Universal orientation, gravity and motion acceleration sensor 20 Jun 2012 | 02:13 am
We have seen a number of fusion possibilities for 2 sensors. We have seen accelerometer supported by gyroscope so that gravity and motion acceleration may be reliably separated. See this Droidcon Tun...
Better motion control using accelerometer/gyroscope sensor fusion 14 May 2012 | 08:11 am
This is my Droidcon Tunis 2012 presentation. Thanks for the great audience in Tunis! Better motion control using accelerometer/gyroscope sensor fusion View more presentations from Gabor Paller.
