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 ( 104 a ; 104 b) 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 ( 107 a-d). A respective control interface ( 107 a-d) with a protocol that is compatible with a protocol of the device interface ( 105 a; 105 b) 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 ( 107 a-d) by accessing a statement included in the document ( 102 ), which statement specifies the control interface ( 107 a-d) to select.
