A foot state management interactive system includes at least one management server, which includes a network unit and a data processing unit. The network unit is configured to perform network communication and communicate with at least one terminal device for foot detection. The data processing unit is electrically coupled to the network unit and is configured to manage foot state information transmitted from at least one foot state detection terminal device. At least one management server is configured to map a first terminal device of at least one foot detection terminal device to a first user, and output a corresponding one based on a change in the first foot status information sent by the first terminal device. The message is sent to the first terminal device to interact with the first user in relation to the first foot state information. In addition, the embodiment also discloses a terminal device for foot detection and a foot detection 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。
