Description
CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of the filing date of an India Provisional Application No. 4363/CHE/2013, filed Sep. 26, 2013, the contents of which are incorporated herein by reference.


TECHNICAL FIELD

The present disclosure generally relates to customized displays and customer-specific functions for keys on a keyboard.


BACKGROUND ART

Manufacturers of many consumer electronic devices, including TVs, DVDs, and DVRs, and mobile devices are currently bundling direct access to services of third-party providers into the platforms of such devices. A device manufacturer may implement a button on a remote or an icon on a mobile device so that an end-user may directly access a specific service from a third-party service provider. For example, an end-user of the remote can conveniently access a preferred service at the push of a button, e.g. selecting a button for an on-demand streaming media provider to gain direct access to a preferred movie selection. Additionally, instead of a button, an end-user of a mobile device may select a dynamic application icon, or a “live title,” to activate a preferred application. The live tile is dynamic in the sense that it can display real-time summary or content information, e.g. displaying the number of new email messages in an end-user's inbox.


However, such conventional techniques are not integrated within a personal computing (PC) space. A lack of access to the services of third-party providers via a personal computing experience presents a barrier between the end-users and the service providers.

In some aspects, each of the keys 102, 104, 106 may include live data, such as “Your order has now shipped,” “You have two messages in your inbox,” and “You have two offers available.”



FIG. 2 is a block diagram of the architecture 200 for the display of an image on a keycap on a keyboard. Various text and words, e.g., custom key images, may be display on the keycaps of a physical keyboard. As illustrated in FIG. 2, the architecture 200 may provide techniques to configure the keyboard 202 for the actual display of the custom key images. The keyboard 202 may be controlled by a Trusted Keyboard Manager (TKM) 204 that is running in a Trusted Execution Environment (TEE) platform 206. In embodiments, the TKM 204 and the TEE platform 206 are a portion of firmware 207. An operating system 209 may manage the system hardware and software resources, including the keyboard 202.


The TKM 204 may be primarily responsible for displaying a custom key image on the keyboard 202. On start-up of a PC device 208, the TKM 204 may have cached a set of generic images, e.g., runtime configurable display images, for display on the keycap of the keyboard 202. Thereafter, the TKM 204 may periodically consult with a platform manufacturer to obtain a list of additional images to display, including auto-complete recommendations or visible passwords. In embodiments, the TKM 204 may consult with cloud services 218 such as a platform manufacturer cloud service 214 or a third party cloud service 216 to obtain the list of additional keys to display.


On startup or during execution of an application 210 belonging to partner service providers, the application 210 can consult with its own service provider to obtain a signed image for a custom key. The application can then register itself (as illustrated at reference number 211) with the Keyboard Manager 212 running in the Operating System 209 or at the application layer and deliver the signed key image to the TKM 204. Thus, during execution of an application 210, the application 210 may deliver the generic custom key image to the TKM 204 for display. The TKM 204 may validate each custom key image before it is displayed by determining its validity and eligibility for display on the keycaps. As illustrated in FIG. 2, the keyboard manager 212 may interface with the keyboard 202 to display the generic custom key images. In the case of a virtual keyboard, the keyboard manager 212 may overlay the custom key images on top of the virtual keyboard of an operating system and may intercept a touch event corresponding to the custom keycaps.


In embodiments, the TKM 204 can automatically request or “get” a key image list from the cloud services 218 as illustrated at reference number 220. A signed image list may be sent to the TKM 204 from the cloud services 218 as illustrated by reference number 222. Similarly, a user can request or “get” a key image from the cloud services 218 as illustrated at reference number 224. A signed key image may be sent to the app 210 from the cloud services 218 as illustrated by reference number 226.


It is to be understood that the block diagram 200 of FIG. 2 is not intended to indicate that the architecture is to include all of the components shown in FIG. 2 in every case. Further, any number of additional components can be included within the block diagram 200, depending on the details of the specific implementation.



FIG. 3 is an illustration of a signed image 300 for display on a customized key. The customized keys may only display images generated and submitted by partners authorized to display on the keyboard. In operation, an authorized partner may deliver an image for display on the keyboard by delivering a signed image structure 300 to a device. As shown in FIG. 3, the signed image 300 may include an image to display 302, an assigned ID 304, a signature 306 generated using an assigned private key, and a public key certificate (cert) chain 308 of the authorized partner. A trusted keyboard manager (TKM) may then verify the signed image 300 by verifying the root of the cert chain 308, verifying each link on the cert chain 308, and validating that the signature 306 was generated by the owner of the private key associated with the last cert in the cert chain 308. If verification is met, the authorized partners may be given a unique identifier, a public/private key pair, and a public key certificate from the platform provider.


On initial startup in the PC space, the TKM may have cached a set of generic validated images to display on the customizable keys of the keyboard. The TKM may then periodically consults with a cloud service of the platform provider to obtain a list of additional keys to display. The cloud service of the platform provider may also be configured to return a list of pre-determined images obtained from a third-party cloud servicer associated with authorized partner. The list may then be delivered back to the TKM, which validates each image as described above.


On startup or during execution of an application belonging to an authorized partner, the application can consult with its own service provider to obtain a signed image structure for a customized key. As described above, the key image may be a specific customized key mapped to a service from a third-party service provider or to an application, as shown in FIG. 1(A), an user-specific opportunities key mapped to dynamic content from a third-party service provider or an application as shown in FIG. 1(B), or a key leased or sold as real-estate on the keyboard by a third-party service provider, as shown in FIG. 1(C). The application may register with the previously mentioned Keyboard Manager running in the operating system or at the application layer and deliver the signed key image to the TKM, which may validate each image. An updated signed key image can be delivered to the TKM periodically, as user content updates may be received by the application from its cloud service.


For each image received, either from a service provider or from an interactive application, the TKM can choose the location of the image on the virtual keyboard. The TKM may first determine if the image is new or a replacement based on the assigned ID number 304. If the image is a replacement image, the image may be displayed on an existing assigned key. If the image is new image, the TKM may prioritize the image among other requested images and assign a new key.



FIG. 4 is a block diagram 400 of architecture for managing the action when a user selects a customized key. If an end-user selects one of the customizable keys on a keyboard 402, a TKM 404 may intercept the pressed key 405 and inform a Keyboard Manager 406 of the identification of that particular key. In operation, the Keyboard Manager 406 may then inform a registered application 408 about the key press event. The application 408 may consult with cloud services 410 such as a platform manufacturer cloud service 412 or a third party cloud service 414. The application 408, during its execution, may then fetch and display opportunity content 416 associated with a opportunity or service 418. For keys delivered directly by a platform provider, and not an application, the Keyboard Manager 406 may consult the platform service 412 provided by a device manufacture to determine an appropriate action 420. In some embodiments, the resulting action 422 can include the launch of a web page. In embodiments, the TKM 404 and a Trusted Execution Environment (TEE) platform 406 are a portion of firmware 424.
