system according to claim 1, further comprising a unit that determines a current use mode of the sheet, wherein of a group of pieces of information accumulated in the accumulation unit, the presentation unit presents a result of analysis based on a piece of information corresponding to the determined current use mode. ### Claim 3 (depends on 1) The information processing system according to claim 1, wherein the presentation unit presents aggregate information which is aggregated by assigning a set weight to each of the relevant information accumulated in association with the underlay mode and the relevant information accumulated in association with the cover mode. ### Claim 4 (depends on 2) The information processing system according to claim 2, wherein the presentation unit presents aggregate information which is aggregated by assigning a set weight to each of the relevant information accumulated in association with the underlay mode and the relevant information accumulated in association with the cover mode. ### Claim 5 (depends on 3) The information processing system according to claim 3, further comprising a unit that, as the weight of each of the underlay mode and the cover mode, holds a value that indicates a degree of deterioration of the sheet per unit time when the sheet is used in the mode, wherein the presentation unit determines a value that indicates the degree of deterioration of the sheet by aggregating an operating time of the sheet in the underlay mode and an operating time of the sheet in the cover mode by assigning the weight for each the underlay mode and the cover mode to the corresponding operating time, and presents the determined value. ### Claim 6 (depends on 4) The information processing system according to claim 4, further comprising a unit that, as the weight of each of the underlay mode and the cover mode, holds a value that indicates a degree of deterioration of the sheet per unit time when the sheet is used in the mode, wherein the presentation unit determines a value that indicates the degree of deterioration of the sheet by aggregating an operating time of the sheet in the underlay mode and an operating time of the sheet in the cover mode by assigning the weight for each the underlay mode and the cover mode to the corresponding operating time, and presents the determined value. ### Claim 7 (depends on 5) The information processing system according to claim 5, wherein when the sheet is used in the underlay mode, the presentation unit displays a first image schematically illustrating a state in which a user sitting on the sheet installed on a seat, when the sheet is used in the cover mode, the presentation unit displays a second image schematically illustrating a state in which the sheet covers a body part of the user sitting on the seat, and a display pattern of the sheet in the first image and the second image is according to the value that indicates the degree of deterioration. ### Claim 8 (depends on 6) The information processing system according to claim 6, wherein when the sheet is used in the underlay mode, the presentation unit displays a first image schematically illustrating a state in which a user sitting on the sheet installed on a seat, when the sheet is used in the cover mode, the presentation unit displays a second image schematically illustrating a state in which the sheet covers a body part of the user sitting on the seat, and a display pattern of the sheet in the first image and the second image is according to the value that indicates the degree of deterioration. ### Claim 9 (depends on 1) The information processing system according to claim 1, further comprising a location identifying unit that identifies a location where the sheet is used, wherein as the relevant information, the accumulation unit accumulates information on the location where the sheet is used identified by the location identifying unit in association with the use mode of the sheet when being used, and the presentation unit presents information indicating a relation between the location and the use mode based on the information accumulated in the accumulation unit. ### Claim 10 (depends on 9) The information processing system according to claim 9, wherein as the information indicating a relation between the location and the use mode, the presentation unit presents information corresponding to a ratio of use of the sheet in the cover mode at the same location. ### Claim 11 (depends on 10) The information processing system according to claim 10, wherein the presentation unit presents the location at which the ratio of use in the cover mode is higher than or equal to a threshold, as a candidate place where a user feels cold in a lower body. ### Claim 12 (depends on 1) The information processing system according to claim 1, wherein the accumulation unit accumulates data detected by a sensor provided in the sheet as the information related to when the sheet is used. ### Claim 13 (depends on 12) The information processing system according to claim 12, wherein the presentation unit obtains from another device on a network secondary information having a predetermined relationship with the data accumulated in the accumulation unit, and presents a result of analysis of the data and the secondary information related to the data in consideration of the use mode. ### Claim 14 (depends on 1) The information processing system according to claim 1, wherein the accumulation unit accumulates data obtained from an external information source of the sheet when the sheet is used as the information related to when the sheet is used. ### Claim 15 (depends on 12) The information processing system according to claim 12, further comprising a determination unit that determines the use mode of the sheet based on the data detected by the sensor provided in the sheet. ### Claim 16 (depends on 15) The information processing system according to claim 15, wherein the sensor provided in the sheet includes one or more first type sensors that detect a load or a pressure applied to the sheet, and when a load greater than or equal to a threshold defined based on a human weight is detected by the one or more first type sensors, the determination unit determines that the sheet is being used in the underlay mode. ### Claim 17 (depends on 16) The information processing system according to claim 16, wherein in addition to the one or more first type sensors, the sensor provided in the sheet includes a second type sensor that detects movement or phenomenon caused by an organic activity of a user in contact with the sheet, and when a load greater than or equal to the threshold defined based on a human weight is not detected by the one or more first type sensors and the phenomenon is detected by the second type sensor, the determination unit determines that the sheet is being used in the cover mode. ### Claim 18 (depends on 17) The information processing system according to claim 17, wherein when a load greater than or equal to the threshold defined based on a human weight is not detected by the one or more first type sensors and the phenomenon is not detected by the second type sensor, the determination unit determines that the sheet is in a non-use state. ### Claim 19 (depends on 1) The information processing system according to claim 1, wherein the presentation unit presents a time during which the sheet is used in the underlay mode or the cover mode as a time during which a user is seated. ### Claim 20 An information processing system comprising: a sheet that is usable in a use mode which is any one of an underlay mode and a cover mode; a determination unit that determines that the sheet is in one of a state in which the sheet is used in the underlay mode, a state in which the sheet is used in the cover mode, and a state in which the sheet is not used, based on data detected by one or more sensors provided in the sheet; and a unit that calculates a time during which a user is seated based on a length of time in which the sheet is determined to be used in the underlay mode or the cover mode by the determination unit.
