Abstract
With increasing reliance on the location and orientation sensors in smartphones for not only augmented reality applications, but also for meeting government-mandated emergency response requirements, the reliability of these sensors is a matter of great importance. Previous studies measure the accuracy of the location sensing, typically GPS, in handheld devices including smartphones, but few studies do the same for the compass or gyroscope (gyro) sensors, especially in real-world augmented reality situations. In this study, we measure the reliability of both the location and orientation capabilities of three current generation smartphones: Apple iPhone 4 and iPhone 4s (iOS) phones, as well as a Samsung Galaxy Nexus (Android). Each is tested in three different orientation/body position combinations, and in varying environmental conditions, in order to obtain quantifiable information useful for understanding the practical limits of these sensors when designing applications that rely on them. Results show mean location errors of 10–30 m and mean compass errors around 10–30°, but with high standard deviations for both making them unreliable in many settings.
