A server is provided. The server provides virtual indoor space content corresponding to a real indoor space. The server includes a memory; a communication module; and at least one processor operatively connected to the memory and the communication module. The at least one processor may receive image data to generate the virtual indoor space content from a mobile terminal through the communication module, the image data including, for each of a plurality of indoor points, an omnidirectional image acquired from each indoor point and relative location information on the indoor point, and generate the virtual indoor space content by mapping a plurality of virtual points corresponding to the plurality of indoor points in a virtual indoor space based on the relative location information.

The disclosed system includes a user-mountable electronic device, an output interface, and at least one processor. The electronic device includes a housing and at least one sensor device located within the housing and configured to generate sensor output that indicates orientation or motion of the user-mountable electronic device. The at least one processor is operated to: receive the sensor output; identify, based on the received sensor output, a body part on which the user intends to deploy the user-mountable electronic device; determine a preferred orientation of the user-mountable electronic device relative to the identified body part; and cause the output interface to provide deployment guidance that indicates the preferred orientation of the user-mountable electronic device.

A calibration apparatus of an inertial sensor, obtains an angular velocity value from the inertial sensor, derives a distribution of a difference between temporally adjacent angular velocity values concerning a plurality of angular velocity values obtained during a given period, and determines, based on the distribution, whether the inertial sensor is in a motionless state during the given period. Then, if it is determined that the inertial sensor is in the motionless state, the calibration apparatus decides a bias value of the inertial sensor based on the plurality of angular velocity values and corrects the obtained angular velocity value based on the bias value.
