  • any applications supporting or servicing the abovementioned ones may also be tracked and/or manipulated.
  • the following exemplary enhancement scenario may take place (FIG 5):
  • the user is surfing the web (e.g. using Internet Explorer) he may have several tabs open; the active tab's thread is enhanced.
  • a downloading application e.g. e-Mule
  • a media player e.g. iTunes
  • MP3 file for the mobile media player (e.g. iPod).
  • flash banners on the on the active tab's website are receiving less Graphic Processing Unit and resources.
  • identification may further include prioritizing of said computational actions or action sets and/or determination of their level of enhancement or diminution.
  • pre-defined enhancement decisions may be configured manually or may be pre-defined per certain activities/situations/scenarios (FIG. 6). For example: a user may want to focus (i.e. to enhance) on a specific on-line game requiring fast internet and disk access while having indexing services running in the background.
  • An exemplary system configuration in which some of the enhancement decisions are pre-defined by the user is shown in figure
  • dynamic enhancement may be initiated or changed based on what the user expects at a specific time.
  • Dynamic enhancement may use various methods and/or inquiries for determining the user expected and/or preferred results, these may include, but are in no way limited to the following examples: a. Tracking the working application - application that the user is currently working with. b. Tracking the visible application - application visible to the user. It may also be any application that the user senses in any other way, like sound. c. Tracking the background applications, those that are running but the user is neither seeing nor using. d. Tracking the background applications that are serving 3 r party applications, such as, Domain Name System (DNS) service, providing access to internet explorer. e.
  • DNS Domain Name System
  • Tracking the working thread inside the application no need to boost all internet explorer tabs while the user is seeing only one.
  • Tracking the working window objects - may be a window, a part of a window, toolbar, tab, flash object, etc.
  • Tracking applications that service working applications for example: Remote Procedure Call (RPC)
  • RPC Remote Procedure Call
  • IE Internet Explorer
  • Tracking needs for resources based on application(s)-peak for example, Internet Explorer (IE) needs to load a page now. This may be done by recognizing that an application is in a certain consumption level, or a certain change or speed of change of a specific resource, triggering re- prioritization. For example, IE consumes more than 30kb/sec. of bandwidth - page is loading - allocate more resources to IE - page download is complete (e.g. IE consumes less than 5kb/sec.) - stop preferred allocation to IE - application needs to load - allocate accordingly.
  • enhancing the performance of applications, processes, threads and/or other computational actions currently being used/engaged by the user may comprise understanding and identifying the computational actions or action sets (e.g. applications, processes) for which performance is to be enhanced and enhancing their performance by allocating them preferred allocation of computational resources, at the expense of those used by some or all of the complementary, 'not to be enhanced' computational actions or action sets.
  • computational actions or action sets e.g. applications, processes
  • an application's own activity may cause it to be designated as important/relevant. Certain activities may be defined as important/relevant activities and applications adapted to engage in such activity may be designated as important when they are actually engaged so engaged. For example, if an application such as a web browser is loading a web-page, and the activity of loading a web-page is defined as an important/relevant activity, resources of application not engaged in activities defined as important/relevant activity may have their resources reallocated to the web-browser.
  • an enhancement may happen substantially immediately, or after a certain threshold is reached or passed.
  • an enhancement may not make sense for every lkb DNS request, a lkb/sec file update, or for every application that the mouse courser has 'touched'.
  • one or more thresholds may be set before an enhancement is actually executed.
  • an enhancement may not be executed under certain conditions. For example, if a certain application is visible, but is consuming no, or substantially modest, resources, there is no need for the enhancement to be executed.
  • Predictive enhancement may prepare the system for what a user's next/following action(s), for which any combination of some or all of the following methods may be used.
  • predictive enhancement decisions may be based on what the user is about to do or intends to do and enhancing certain resource allocations in preparation for these user actions.
  • Various methods and/or inquiries may be used for predicting user intentions/future-actions, these may include, but are in no way limited to, the following examples: a. Tracking the mouse movements may indicate in many cases where the user is looking and where the user is going to click next. At this point, it may be helpful to prepare the application, thread, object, etc. to react immediately to this user's mouse behavior.
  • This type of prediction may, for example, trigger the operation of a given application icon towards which the user's mouse is advancing and thus may lessen the time span between the instant when the user clicks and the instant when said applications window has fully responded.
  • Tracking of various other pointing devices may be used in a substantially similar way.
  • tracking the mouse movements may indicate where the user is looking and where the user is going to click next (FIG. 8). At this point, it may be helpful to prepare the application, thread, object, etc. to react immediately to the user's actions. Tracking the cursor caret may be used in a substantially similar way as the mouse curser movements when keyboard is used. Furthermore, any other pointing device, known today or to be devised in the future, may be substantially similarly used. Predictive enhancement may substantially affect the user's experience by initiating the uploading of what the user wants (i.e. soon to command/request) prior to the temporal instant of the actual interfacing.
  • predictive enhancement may track applications recently started by the user. Such application(s) may not be visible yet (as opposed to the mouse movement tracking where applications are already open). As the majority of the users consider a PC to be fast in accordance with the speed of a newly engaged application showing, satisfying this condition with a substantially immediate application opening, even if other functionalities of the application where delayed as a result, may create an impressive improvement of user experience. Certain newly started applications may not be enhanced. Applications started by other visible applications, for example, may be handled as those started by the user and may thus be enhanced, whereas background applications may start other background applications which may not necessarily need an enhancement, as their enhancement may not be acknowledgeable by the user.
  • the monitoring module may predicatively estimate or guess a given application's importance to the user (i.e. the user is about to use the application) based on mouse cursor location.
  • the application may monitor and take into consideration proximity (FIG. 9A) and velocity (direction and speed) (FIG. 9B) of the mouse cursor relative to a screen or other interface elements of the given application when predicting whether the user is about to interact with the given application, thereby making the given application an important/relevant application.
  • mouse cursor proximity to a screen/interface-element of a given application may indicate importance/relevance of the application to the user.
  • a decision on how to rearrange the computer resources' access and allocation may be reached.
  • main enhancement levels may be selected from: Full, Partial, None, and
  • the enhancement may be applied by slow-down to any object in the computer, operating system, subsystem or application. It is important to notice that throughout this document the concepts and terms related to the 'enhancement' and/or
  • 'slow-down' may be named and/or referred to by use of different names, for contextual and ease of understanding related reasons.
  • Partial - application is visible / noticeable, but the user is not working with it.
  • a YouTube stream running in the background may be visible on the screen while the user is working on another application, or it may be in the background, but the user can hear it. With this scenario, the YouTube stream is what the user is looking for, but it is not where his attention is focused.
  • Another example is a web page containing many visual flash commercials that drain CPU power. Most users will be working on another application leaving this window visible.
  • Graphics may be slowed down, or refresh rate dropped partially because the user is still expecting to get a reasonable graphics experience.
  • None - some applications may be untouched, for example, due to stability issues.
  • Slowdown - enhancement of other applications is achieved by sacrificing these particular applications, or parts of their execution time, and actively slowing them down by limiting their access to various system resources.
  • enhancement may be implemented in the context of changing processes' priorities and allowing more execution time for one or more prioritized processes. Further focus may be given to user expectations and thus quality-of-service may be enhanced by actively slowing down to various levels all or a part of the non needed contenders contending on a needed resource by the enhanced application(s).
  • the slow-down may sacrifice certain resource elements (e.g. cause a degradation of quality, a dropping of IO messages) in order to allocate resources for applications of higher importance/priority.
