A device worn by a human performing a method using accelerometer data to classify human activities is disclosed. The method uses memory and computation efficiently. A stream of samples is divided into a sequence of sampling periods; each sample has an acceleration value for each axis (e.g., a 3-D accelerometer). Standard deviation of the values for each axis during each sampling period are calculated. A running sum of each axis' values can be maintained sample-by-sample. Each value is sorted into a bin of a histogram, by quantifying a deviance from a respective mean in standard deviations. A standard deviation produced from samples of a previous period can be used. The histogram is compared with histograms associated with particular activities and a classification output can be produced. Classification outputs from multiple sampling periods can be used for voting. A threshold amount of activity can be required to begin activity classification.

Efficient activity classification from motion inputs

A plurality of clients are connected to one or more servers. When a client initiates a connection with a server, the server responds to the request for connection by transmitting a message back to the client to determine whether the client is a network terminal or not. The client responds with a message that is received by an application dispatcher at the server which takes one of a pair of actions based on whether the client is a network terminal. If the client terminal is a network terminal, then the application dispatcher starts a server application in the server which responds to the client application in the client. Going forward, the server application responds to all future requests from the client application. If the client is not a network terminal, then the application dispatcher initiates a client application in the server to service the client terminal application requirements. Requests from the client application on behalf of the client terminal are subsequently serviced by a server application at the server which communicates to the client terminal via the client application at the server. In one embodiment, the application dispatcher includes a listener. The listener is assigned to a particular port number of the server. The listener is responsible for waiting for new incoming connections from a client terminal (e.g., a network terminal or a non-network terminal). When a new incoming connection is detected, the listener dynamically instantiates a resolver and passes the connection to the resolver. The behavior of the resolver can vary depending on the port number and requirements of the client terminal. For example, for a network terminal, such as a commercially available VeriFone Personal ATM.TM. (PATM.TM.) appliance or a Personal Computer (PC), the resolver is responsible for executing 'who are you' negotiation and for generating a session key.
