CONTROL INTERFACE SELECTION

摘要

A software entity (101) e.g a web-browser, arranged to be run on a control computer (103) which can be networked with controllable devices (104a; 104b) e.g. PDAs and/or Mobile phones to transmit a signal from the control computer to the controllable devices as a result of processing a document (102) which defines operations to be performed by the software entity (101); the control computer (103) is arranged to comprise a collection (106) of control interfaces (107a-d). A respective control interface (107a-d) with a protocol that is compatible with a protocol of the device interface (105a; 105b) of a given device is employed to provide communication between the control computer and the given controllable device. The software entity (101) is arranged to determine which control interface (107) to select from the collection (106) of control interfaces (107a-d) by accessing a statement included in the document (102), which statement specifies the control interface (1 07a-d) to select.
