Provided is a self-propelled reading device to read cards more reliably. Each of the cards includes a first end part configured to be adjacent to another card in a predetermined direction; a second end part configured to be on the opposite side of the first end part and adjacent to another card different from the first end part; and a surface printed with a pattern in which are coded coordinates indicating a positional relation relative to a reference line extended in the predetermined direction indicative of a region in which a self-propelled device is to travel. Each of the first and the second end parts has a positioning part regulating how the other card adjacent to the end part is to be placed. The positioning parts and the reference line have a predetermined positional relation therebetween.

A method for providing a racing game using an autonomous driving unit includes: outputting route information of a specific autonomous driving unit participating in the racing game; receiving mission performance information for a user mission which a participant or a team is to perform; adjusting the route information by referring to the mission performance information; applying the adjusted route information to driving of the autonomous driving unit; and determining a result of the driving of the participant or the team.

A robotic system is integrated with one or more mobile computing devices. Physical configurations of individual components of the system in physical space, or agents, under control of a user or users, are duplicated in a representation in virtual space. Some degree of real-time parity is maintained between the physical and virtual spaces, so as to implement a virtual environment that mirrors the physical one. Events occurring within one environment can directly influence and bear consequence on the course of events occurring within the other environment. Elements of virtual space thereby become truly interdependent and unified on a peer footing with elements in physical space. In at least one embodiment, the system is implemented as an application in entertainment, such as the manifestation of a video game in physical space.
