I'm in a Minneapolis hotel bar Slick, dark and red-lit Sipping a husky tempranillo Resting after a busy day Mindlessly checking email on my phone Reading the latest headlines Minding my own business.
I ask her what she thinks about the over-the-phone readings some psychics are turning to.
That will probably mean combining positioning information from multiple sensors in a smartphone: Wi-Fi and mobile-phone signals, GPS readings, data from accelerometers and gyroscopes, and images of the surroundings from the phone's camera.
I just wandered over to the Spice booth to see their weird optical-disk-reading phone.
Although the phone's compass angle readings changed considerably depending on the phone's placement orientation, we found that we can use the compass sensor's reading regardless the mobile phone's placement or orientation.
From these two figures, it is obvious that the mean is not zero even when the phone is static, the readings of acceleration in three axes fluctuate frequently over the time domain, and the errors also change in different orientations.
8 This linked via Bluetooth connection to a mobile phone, which automatically transmitted readings to a central server managed by IEM Ltd (Stuttgart, Germany).
17 This was linked by a short range wireless connection to a mobile phone, which automatically transmitted readings to a central server managed by IEM.
We did an experiment to check the readings of the phone's orientation sensor when the phone is carried in different positions, and to see whether the orientation sensor could still accurately detect a user's walking path turning points and variation.
