Abstract: An information processing system includes a portable sheet having a first face and a second face, a sensing unit that senses a physical quantity acting on the first face and a physical quantity acting on the second face, and a controller that executes a control based on a combination of physical quantities, the combination of physical quantities being a combination of the sensed physical quantity acting on the first face and the sensed physical quantity acting on the second face.

Abstract: An information processing system includes a sheet-shaped apparatus placed in a specific place, the sheet-shaped apparatus including a sensor built in the sheet-shaped apparatus to sense information indicating whether a user is present over the place in which the sheet-shaped apparatus is placed, an acquiring unit that acquires environmental information about the place, and a providing unit that provides information based on the information sensed by the sensor and on the environmental information acquired by the acquiring unit.

Abstract: A processing system includes a sheet-shaped device, a determination unit, and a controller. The sheet-shaped device is attachable to a seat in an area from a seat surface of the seat to a surface of a backrest of the seat. The sheet-shaped device includes a sensor that detects whether a user is sitting on the seat surface and that detects whether the user is leaning against the surface of the backrest. The determination unit determines a type of sitting posture of the user by using a signal from the sensor. The controller controls a control target in accordance with the determined type of sitting posture.

Abstract: An information processing system includes: a sheet that is usable in a use mode which is any one of an underlay mode and a cover mode; an accumulation unit that accumulates relevant information related to when the sheet is used in association with the use mode of the sheet when being used; and a presentation unit that presents a result of analysis of the information accumulated in the accumulation unit, in consideration of the use mode.
