Abstract: An apparatus [100] includes an application layer [205] to present an application behavior specification and a presentation specification. An engine layer [305] receives at least one input corresponding to a proposed modification to at least one of the application behavior specification and the presentation specification. A modality interface layer [215] interprets the at least one input and merges the at least one input into an output. An interaction management layer [210] (a) receives the output; (b) determines permitted modifications to the at least one of the application behavior specification and the presentation specification based on a set of pre-defined rules; and (c) generates a new application by modifying the at least one of the application behavior specification and the presentation specification at run-time based on the permitted modifications.

Abstract: A method (200) and mobile device (120, 130) for silently fetching data is disclosed. In one arrangement, the method can include the steps of receiving (218) a silent fetch request from an originating device (120) over a wireless communication channel (300) in which the silent fetch request requests information and checking (220) the authorization of the originating device. If the originating device is an authorized device, the requested information can be fetched (222) and transmitted (224) to the originating device. As an example, the requested information can be fetched from a receiving device (130) or from a network server (140) with which the receiving device is associated. As another example, the wireless communication channel can be a traffic channel that supports at least push-to-talk communications.

Abstract: When a wireless two-way communications device that has a plurality of user interfaces (and where at least two of these interfaces comprise different interface modalities) receives (101, 201) non-user input regarding an operational constraint (such as, but not limited to, an environmentally-sourced or an internally-sourced operational constraint), an automatic determination (102, 202) will follow regarding a plurality of differing user interface operational configurations as will comply with the operational constraint. One or more of these operational configurations are then presented (103, 203) to a user of the device in order to prompt provision of a user instruction regarding use of such operational configurations. Upon receiving (104, 204) a corresponding instruction from the user, the corresponding operational configuration is used (105, 205) to thereby accommodate the operational constraint in a manner that is relatively satisfactory to the user.
