Abstract

Embodiments relating to facilitating communication between an adaptive input device and a device desktop application program in a computing system are disclosed. One example embodiment includes a computing system that comprises an device desktop and an adaptive device input/output module that is configured to receive an output command from the device desktop application program; identify an image rendering protocol of the device desktop application program in the device desktop; and create an image of the one or more user interface elements according to the image rendering protocol.

4. The computing system of claim 3, where the predefined presentation mark-up language is an extensible application mark-up language (XAML);

and

where the adaptive device input/output module, in creating the image according to the first image rendering protocol is configured to;

transmit a user interface change indicator to the device desktop application program, the user interface change indicator configured to cause the device desktop application program to transmit a notification message to the adaptive device input/output module responsive to a user interface event; and

in response to receiving the notification message from the device desktop application program, render a bitmap grid as the image of the one or more user interface elements to be forwarded to the adaptive input device for display.

5. The computing system of claim 3,

where the adaptive device input/output module, in creating the image according to the second image rendering protocol is configured to:

create an image buffer;

print the image to the image buffer; and

retrieve the image from the image buffer, which is responsive to a user interface event, to be forwarded to the adaptive input device for display.

6. The computing system of claim 3, where the adaptive device input/output module is further configured to receive touch input from the adaptive input device;

if the output command is formatted according to the predefined presentation mark-up language, then the adaptive device input/output module is configured to format the touch input as an adaptive input device message according to a first message formatting protocol;

if the output command is not formatted according to the predefined presentation mark-up language, then the adaptive device input/output module is configured to format the touch input as an adaptive input device message according to a second message formatting protocol; and

forward the adaptive input device message to the device desktop application program.

7. The computing system of claim 1, further including the adaptive input device;

wherein the touch input system of the adaptive input device includes at least one mechanical depressible button for receiving the touch input; and

wherein the graphical display system of the adaptive input device includes a graphical display disposed on the mechanical depressible button for presenting the one or more user interface elements of the device desktop application program.

9. The computing system of claim 1, where the device desktop is further configured to receive from the adaptive input device non-touch input in the form of voice input via a microphone, three dimensional gestures from a three dimensional image sensor, and/or a presence indicator from a presence sensor that detects a presence of a user in a vicinity of the adaptive input device.

8. The computing system of claim 8, further comprising an access control service configured to:

determine whether the hidden desktop application is an approved application;

if the hidden desktop application is an approved application, then permit the one or more adaptive user interface elements to be displayed at the adaptive input device; and

if the hidden desktop application is not an approved application, then prohibit the adaptive user interface elements from being displayed at the adaptive input device.

10. A method of facilitating communication between an adaptive input device and a device desktop application program managed by an operating system of a computing device, the method comprising:

receiving an output command from the device desktop application program, the output command including one or more user interface elements of an input device user interface;

if the output command is formatted according to a predefined presentation mark-up language, then creating an image of the one or more user interface elements according to a first image rendering protocol;

if the output command is not formatted according to the predefined presentation mark-up language, then creating an image of the one or more user interface elements according to a second image rendering protocol; and

forwarding the image to the adaptive input device for display.

11. The method of claim 10, further comprising, determining whether the output command is formatted according to the predefined presentation mark-up language.
