Time Machine is an Augmented Reality (AR) system for enhancing tourists' traveling experience. Based on optimized panoramic images, we proposed a novel spatiotemporal interactive approach which imbues users the ability to interact with both the spatial world and its history. Time machine utilizes panorama of a specific place at different time for achieving interactions with temporal dimension. It also adopts interior panorama of landmark building which can be used by the user to interact with the physical world. Additionally, the panoramas optimized by aperture-coded camera can alleviate the noisy foreground information such as crowds and address defocus blurring to improve the quality of panorama.
