Description

Technical Field

[0001] The utility model belongs to the technical field of pressure data collection, and in particular relates to an interactive pressure data collection device with action feedback. Background Art

[0002] The movement patterns and force intensity of human hands show a significant correlation with the individual's psychological state. Psychological research shows that by quantitatively analyzing the pressure distribution characteristics generated during hand interaction, it is possible to effectively evaluate the subject's emotional state, personality tendencies and other psychological dimension parameters. This provides a new technical path for psychological experimental research and emotional computing of intelligent interactive devices.

[0003] Usually, a pressure sensor array is used to realize multi-point pressure detection. The pressure sensor array is set on the surface of the object. When the human hand comes into contact with the object, the pressure distribution data of the contact area can be obtained by measuring the pressure value of each point. For example, patent document CN110006557A proposes a flexible pressure monitoring pad, which can be set on the surface of an object to collect individual pressure data. However, the current pressure data acquisition device is only used to collect pressure data and lacks interactive functions, so that individuals cannot obtain effective feedback during the test, which may induce rejection psychology and cause the data validity to decrease.
