  "textContent": "\"A proximity detection device and an information processing system\" which suppress omission of acceptance of an operation due to reflection by a user's wrist or arm are provided. [0002] When a right-moving gesture operation of moving the hand close to the display (2) from left to right in the display (2) is performed (a), the transition of the position where the hand returns to the left side due to the reflection by the wrist or the like may be detected (b). The detection control unit (323) which detects the approach of the hand to the display (2) and notifies the data processing device (1) of the position of the hand notifies the data processing device (1) of non-detection of hand approach at the time Pd when the amount of movement dx of the position of the hand to the right direction starts to decrease after exceeding the threshold value Th. The data processing device (1) calculates the amount of movement Δx to the right direction from the position xS when the detection of the approach of the hand is started until the position xPd-1 immediately before the time Pd when notification of the non-detection is provided, and accepts the right-moving gesture operation to perform a predetermined process when the amount of movement Δx exceeds the threshold value Th (d).",
