Abstract

A method of styling a user interface for a device (400), and a device (400) having an adaptive user interface. Style information for the user interface is received. This style information is associated with nodes in a hierarchical tree, each node in the tree corresponding to a device characteristic. Each node corresponds to a more specific device characteristic than its parent node. A best matching node in the hierarchical tree is chosen, and style information for the chosen node and all parents of the chosen node is collected. The collected style information is then applied to the user interface.

Claims

1. A method of styling a user interface for a device, comprising obtaining style information for the user interface, the style information being associated with nodes in a hierarchical tree, each node in the tree corresponding to a device characteristic, whereby a child node corresponds to a more specific device characteristic than its parent node, choosing a node in the hierarchical tree, collecting style information for the chosen node and all parents of the chosen node, and applying the collected style information to the user interface.

2. The method of claim 1, wherein the chosen node corresponds to a device characteristic that matches the device.

3. The method of claim 2, wherein the chosen node is the lowest node in the tree corresponding to a device characteristic that matches the device.

4. The method of claim 1, wherein style information at a first level of the tree is made available in a first style sheet document, style information at a second level of the tree, lower than the first level, is made available in a second style sheet document, and a link is provided in the first style sheet document to the second style sheet document.

5. The method of claim 4, wherein the link to the second style sheet document is provided through a link element within the scope of a language element representing a parent of a node associated with style information in the second style sheet document.

6. The method of claim 1, further comprising determining a shortest path in the tree from the top node to the chosen node, and collecting the style information associated with the nodes on the shortest path.

7. The method of claim 6, further comprising collecting the style information starting with the top node.

8. The method of claim 1, further comprising transmitting the collected style information to the device before applying the collected style information to the user interface.

9. A device having an adaptive user interface, comprising means for obtaining style information for the user interface, the style information being associated with nodes in a hierarchical tree, each node in the tree corresponding to a device characteristic, whereby a child node corresponds to a more specific device characteristic than its parent node, and user interface means for choosing a node in the hierarchical tree, collecting style information for the chosen node and all parents of the chosen node, and applying the collected style information to the user interface.

10. A computer program product comprising means for obtaining style information for a user interface for a device, the style information being associated with nodes in a hierarchical tree, each node in the tree corresponding to a device characteristic, whereby a child node corresponds to a more specific device characteristic than its parent node, and user interface means for choosing a node in the hierarchical tree, collecting style information for the chosen node and all parents of the chosen node, and applying the collected style information to the user interface.
