There is provided an information processing device including: a global map acquiring unit that acquires at least a part of a global map representing positions of objects in a real space where a plurality of users are in activity; a local map generating unit that generates a local map representing positions of nearby objects detectable by a device of one user among the plurality of users; and an updating unit that updates the global map based on position data of objects included in the local map.

Electric charges depending on values of Nelectric signals and values of corresponding positive loads are held in first capture-and-storage circuitry. Electric charges having a size depending on values of (N&#x2212;N) electric signals and corresponding absolute values of negative loads are held in second capture-and-storage circuitry. A sum of Nmultiplied values obtained by multiplying each of the positive loads by each of the values of the Nelectric signals is calculated when a voltage held in the first capture-and-storage circuitry reaches a first threshold. A sum of (N&#x2212;N) multiplied values obtained by multiplying each of the absolute values by each of the values of the (N&#x2212;N) electric signals is calculated when a voltage held in the second capture-and-storage circuitry reaches a second threshold A sum of N multiplied values is obtained by subtracting the sum of (N&#x2212;N) multiplied values from the sum of Nmultiplied values.
