Zhuang et al. study the energy efficiency of location sensing in 1. First, they put forth of battery effects of location sensing, then they suggest new location sensing methods. They explain that these methods improve the battery life by up to 75% by reducing the number of GPS invocations. This work is close to our study in terms of location sensing. However, in our work other factors in AR applications are also considered and different GPS and sensor processing methods are analyzed in terms of energy consumption.
