摘要:
The present invention relates to a system, method and medium for receiving and acting upon user input. In one embodiment, the user may only have access to a limited input device, like a stylus. Using the present invention, a user is provided with intuitive responses from the system based on inputs from the limited input device.

A digital rights management system for the distribution, protection and use of electronic content. The system includes a client architecture which receives content, where the content is preferably protected by encryption and may include a license and individualization features. Content is protected at several levels, including: no protection; source-sealed; individually-sealed (or “inscribed”); source-signed; and filly-individualized (or “owner exclusive”). The client also includes and/or receives components which permit the access and protection of the encrypted content, as well as components that allow content to be provided to the client in a form that is individualized for the client. In some cases, access to the content will be governed by a rights construct defined in the license bound to the content. The client components include an object which accesses encrypted content, an object that parses the license and enforces the rights in the license, an object which obtains protection software and data that is individualized for the client and/or the persona operating the client, and a script of instructions that provides individualization information to a distributor of content so that the content may be individualized for the client and/or its operating persona. Content is generally protected by encrypting it with a key and then sealing the key into the content in a way that binds it to the meta-data associated with the content. In some instances, the key may also be encrypted in such a way as to be accessible only by the use of individualized protection software installed on the client, thereby binding use of the content to a particular client or set of clients.

A server architecture for a digital rights management system that distributes and protects rights in content. The server architecture includes a retail site which sells content items to consumers, a fulfillment site which provides to consumers the content items sold by the retail site, and an activation site which enables consumer reading devices to use content items having an enhanced level of copy protection. Each retail site is equipped with a URL encryption object, which encrypts, according to a secret symmetric key shared between the retail site and the fulfillment site, information that is needed by the fulfillment site to process an order for content sold by the retail site. Upon selling a content item, the retail site transmits to the purchaser a web page having a link to a URL comprising the address of the fulfillment site and a parameter having the encrypted information. Upon following the link, the fulfillment site downloads the ordered content to the consumer, preparing the content if necessary in accordance with the type of security to be carried with the content. The fulfillment site includes an asynchronous fulfillment pipeline which logs information about processed transactions using a store-and-forward messaging service. The fulfillment site may be implemented as several server devices, each having a cache which stores frequently downloaded content items, in which case the asynchronous fulfillment pipeline may also be used to invalidate the cache if a change is made at one server that affects the cached content items. An activation site provides an activation certificate and a secure repository executable to consumer content-rendering devices which enables those content rendering devices to render content having an enhanced level of copy-resistance. The activation site “activates” client-reading devices in a way that binds them to a persona, and limits the number of devices that may be activated for a particular persona, or the rate at which such devices may be activated for a particular persona.

The present invention relates to methods and apparatus for increasing the perceived quality of displayed images. This is achieved in a variety of ways including the use of a plurality of device specific display characteristics when preparing images for display. It is also achieved through the monitoring of display device and/or ambient light conditions, e.g., on a periodic basis, and using the obtained information when controlling display output. Another approach to improving the perceived quality of displayed images involves the use of information relating to a specific user's ability to perceive image characteristics such as color. By customizing display output to an individual user's own physical perception capabilities and/or viewing characteristics it is possible to enhance the image quality perceived by the individual viewer as compared to embodiments which do not take into consideration individual user characteristics.
摘要:
Methods are provided for interpreting a touch in relation to touch targets displayed on a touch-screen display, the touch targets associated with an application. A touch is detected at a first touch-screen location. The application is queried to determined a first touch target located within a predetermined touch region of the first touch-screen location. The application is then queries to determine whether a second touch target is located within the predetermined touch region. The touch is them disambiguated to determine whether the touch was intended for the first touch target or the second touch target.
摘要:
Computer-readable media, computerized methods, and computer systems for intuitively invoking a panning action (e.g., moving content within a content region of a display area) by applying a user-initiated input at the content region rendered at a touchscreen interface are provided. Initially, aspects of the user-initiated input include a location of actuation (e.g., touch point on the touchscreen interface) and a gesture. Upon ascertaining that the actuation location occurred within the content region and that the gesture is a drag operation, based on a distance of uninterrupted tactile contact with the touchscreen interface, a panning mode may be initiated. When in the panning mode, and if the application rendering the content at the display area supports scrolling functionality, the gesture will control movement of the content within the content region. In particular, the drag operation of the gesture will pan the content within the display area when surfaced at the touchscreen interface.

An interface is provided between a handwriting receiving panel and an auto complete process. A user writes onto the handwriting receiving panel which recognizes the handwritten text. The handwritten text is forwarded to the auto complete process which provides suggested content to the user based on the handwritten text. The user can select the suggested content for use with another application. Alternatively, the user may add additional information to the handwriting receiving panel to enable the auto complete process to provide more or different suggested content.
摘要:
Aspects of the present invention reduce the number of false positive touch inputs made by a non-stylus object such as the user's finger or hand. When the stylus is located proximate to the touch-sensitive surface, the sensitivity of the surface to non-stylus input is disabled, reduced, or otherwise modified. For example, non-stylus inputs may be ignored while the stylus is within a proximity zone defined near the touch-sensitive surface. Further aspects of the present invention are directed to adjusting the threshold requirements of a non-stylus input depending upon where on the touch-sensitive surface the input is made. Still further aspects of the present invention are directed to calibrating various sensitivity thresholds for non-stylus input, as well as the size and/or shape of the proximity zone.
