This invention provides a foot state management interaction system including at least one management server including a network unit and a data processing unit. The network unit is used for network communication and is in communication with at least one terminal device for detecting a foot state. The data processing unit is electrically coupled to the network unit and is used for managing foot state information transmitted by the at least one terminal device for detecting the foot state. The at least one management sensor is used for matching a first terminal device in the at least one terminal device for detecting the foot state with a first user and outputting a corresponding message to the first terminal device based on the change of the first foot state information transmitted by the first terminal device so as to perform an interaction relevant to the first foot state information with the first user. In addition, the embodiment further discloses the terminal device for detecting the foot state and a foot state detecting system.一種足態管理互動系統，包括至少一管理伺服器，其包含網路單元及資料處理單元。網路單元用以進行網路通訊並與至少一足態偵測之終端裝置通訊。資料處理單元電性耦接於網路單元，並用以對至少一足態偵測之終端裝置所傳來的足態資訊進行管理。至少一管理伺服器係用以將至少一足態偵測之終端裝置中之第一終端裝置對應至第一使用者，以及基於第一終端裝置所發出之第一足態資訊的變化而輸出對應之訊息至第一終端裝置，以與第一使用者進行與第一足態資訊相關之互動。此外，實施例還揭示足態偵測之終端裝置與足態偵測系統。
