     DETAILED DESCRIPTION 
     Embodiments of the invention are described below with reference to drawings in detail. 
     Referring to  FIG. 1 , a schematic of a processing system  100  is shown wherein the methods of this invention may be implemented. The processing system  100  is only one example of a suitable system and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, the system  100  is capable of implementing and/or performing any of the functionality set forth herein. In the system  100  there is a computer system  112 , which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with the computer system  112  include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, handheld or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like. 
     The computer system  112  may be described in the general context of computer system-executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. The computer system  112  may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices. 
     As shown in  FIG. 1 , the computer system  112  in the system environment  100  is shown in the form of a general-purpose computing device. The components of the computer system  112  may include, but are not limited to, a set of one or more processors or processing units  116 , a system memory  128 , and a bus  118  that couples various system components including the system memory  128  to the processor  116 . 
     The bus  118  represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include the Industry Standard Architecture (ISA) bus, the Micro Channel Architecture (MCA) bus, the Enhanced ISA (EISA) bus, the Video Electronics Standards Association (VESA) local bus, and the Peripheral Component Interconnects (PCI) bus. 
     The computer system  112  typically includes a variety of computer system readable media. Such media may be any available media that is accessible by the computer system  112 , and it includes both volatile and non-volatile media, removable and non-removable media. 
     The system memory  128  can include computer system readable media in the form of volatile memory, such as random access memory (RAM)  130  and/or a cache memory  132 . The computer system  112  may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, a storage system  134  can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to the bus  118  by one or more data media interfaces. As will be further depicted and described below, the system memory  128  may include at least one program product having a set (e.g., at least one) of program modules  142  that are configured to carry out the functions of embodiments of the invention. 
     A program/utility  140 , having the set (at least one) of program modules  142 , may be stored in the system memory  128  by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating systems may have one or more application programs, other program modules, and program data or some combination thereof, and may include an implementation of a networking environment. The program modules  142  generally carry out the functions and/or methodologies of embodiments of the invention as described herein. 
     The computer system  112  may also communicate with a set of one or more external devices  114  such as a keyboard, a pointing device, a display  124 , a tablet, a digital pen, etc. wherein these one or more devices enable a user to interact with the computer system  112 ; and/or any devices (e.g., network card, modem, etc.) that enable the computer system  112  to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces  122 . These include wireless devices and other devices that may be connected to the computer system  112 , such as, a USB port, which may be used by a tablet device (not shown). Still yet, the computer system  112  can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via a network adapter  120 . As depicted, a network adapter  120  communicates with the other components of the computer system  112  via the bus  118 . It should be understood that although not shown, other hardware and/or software components could be used in conjunction with the computer system  112 . Examples include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc. 
       FIG. 2  depicts a functional set of components and a flow of control for monitoring user initiated movements of a device and controlling sensitivity of the device based on detecting changes. Monitor and control a device sensitivity component  210  may be implemented in a computer system  112  including I/O interface(s)  112  that capture user control and devices metrics. The metrics captured may reflect movement against a surface, a rotation, a change of position or any other user initiated movement controlling a device. The operating system typically provides an infrastructure to capture the movement and interfaces to allow the movement to be processed by an application. The application may have menu items allowing a user to select entries on a graphical user interface (GUI) or may allow a user to control and adjust images or icons represented on a screen or in a physical system. Examples include, but are not limited to image manipulation, drawings, charts, avatars, character movement such as in a game console, and a mechanical device controlling a device at a distance. The feedback of the movement may be presented as a visual feedback by showing updates on screen or even on virtual 3D glasses. In some example embodiments, the updates may be contained within the computer system  112  and visual feedback may be determined by an application running on the computer system  112  and shown on display  124 . In other example embodiments, an application running on the computer system  112  may be utilizing I/O interfaces  112  to interface with an external device  114  to remotely control or operate the external device  114 . The external device  114  could be small and control, for example, a laparoscopic surgery or large and, for example, control an arm of a grasping device on a space shuttle. Feedback to the user from the external device  114  may be via an image captured by a camera. The metrics are received by the monitor and control a device sensitivity component  210  which receives a first controlling motion of a user causing a first directional rate of movement of a device. The process receives a second controlling motion of the user causing a second directional rate of movement of the device. The process compares the second directional rate of movement of the device to the directional rate of movement to determine a device movement change and controls the device sensitivity based on the device movement change. The monitor and control a device sensitivity component  210  may support application programming interfaces (APIs) allowing applications to communicate application states to the monitor and control a device sensitivity component  210 . 
     An aspect of the invention is described in an example scenario. The user movement metrics that control the device movement are processed by the system. The system interprets the user movements as device movements and maps the user movements to device metrics. During the conversion of the user movement to device movement, the monitor and control a device sensitivity component  210  may change the interpretation of the user movement to device movement to control the sensitivity of the device to the user movements. The device metrics, or device input data, may be converted and represented in memory structures as directional vectors. 
     In the example scenario, the system compares the directional vectors periodically by opposing direction monitor  220  which calculates a change of vector rate and compares the change of vector rate to a change of direction adjustment criteria. If the change of direction rate meets a change of direction adjustment criteria, the flow of control proceeds to lower sensitivity  250  which updates the sensitivity setting  270  and the flow returns to control device input  210 . In an embodiment, the change of direction adjustment criteria reflects missing a target and a backward or corrective movement. By lowering the device sensitivity  250  more movement is required by the user to cause the device to move at the same rate with the previous sensitivity. If the change of direction rate does not meet the direction change adjustment criteria, the flow of control proceeds to leave the current sensitivity setting alone  230  and the flow returns to monitor and control device sensitivity component  210 . 
     Another aspect for monitoring and control device sensitivity component  210  is to analyze the device movement data by magnitude change monitor  240 . The magnitude change monitor  240  checks for changes in the amount of movement of the device in a manner similar to the opposing direction monitor  220 . The amount of movement change may be determined by calculating a magnitude difference between the second vector and the first vector. The magnitude difference is compared to a change of magnitude adjustment criteria. If the magnitude difference meets the magnitude adjustment criteria, the flow proceeds to change the sensitivity  260  transferring control to update sensitivity setting  270  and the flow proceeds to monitor and control sensitivity setting  210 . If the change of magnitude is increased, then the user is trying to move the device faster and the process increases the device sensitivity. Increasing the sensitivity requires less user movement to cause the device to move at the same rate with the previous sensitivity. If the change of magnitude is decreased then the user is trying to move the device slower and the process decreases the device sensitivity. The adjustment that decreases the sensitivity allows for more user movement to move the device less. This may be considered a finer granularity of control. The components may be separated or be combined, for example, in the device support, in the operating system, or in the application process  142  making calls to other components. All the process steps in  FIG. 2  may be performed by the monitoring and control device sensitivity component  210 . 
       FIG. 3  depicts a more detailed flow of an example embodiment depicting an aspect of the invention described herein. In the example embodiment, the device is a mouse and the user moves the mouse against a surface. The default for dynamic sensitivity activated  300  is on and the flow proceeds to sensor monitoring  310 . The sensor monitoring  310  corresponds to monitor and control a device sensitivity component  210  which monitors user initiated device movement changes. If no significant changes from normal usage are detected the process proceeds to no significant change detected  330  and no further action is taken. If significant changes are detected, the process proceeds to detect significant user device movement change  335  and continues to determine a type of change  340 . There are three types of changes that may be detected. 
     A first type of change is a normal use detected  355  which corresponds to step  230 . From step  355 , the process proceeds to normalize the dots per inch (DPI) to the user profile  315 . In this case, the user has performed an operation that is consistent with a user profile (learned normal use and preferences)  315 . Various approaches may be used to create the user profile  315 . One approach may be to start from statistical information gathered from many users related to the device. The information could range from generic usage to application specific with details related to application operations. Another approach may be to capture a history specific to the user and utilize a user interface allowing the user to indicate preferences. Again the preferences could range from generic usage to application specific with details related to application operations or even specific menu items or application states. The system may support defaults for new applications, for example, by the type of new application. 
     At step  340 , a second type of change, a smaller, controlled  320  condition may be detected and the DPI is lowered  325 . This corresponds to steps  220 ,  250 , and  270 . The conditions for the DPI is lowered  325  operation is received by sensor monitoring  310  and communicated to user profile  315  which contributes to establishing a history of usage. At step  340 , a third type of change, a broader, sweeping  335  condition may be detected and the DPI is increase  325 . This corresponds to steps  240 ,  260 , and  270 . The conditions for the DPI is increased  360  operation is received by sensor monitoring  310  and communicated to user profile  315  which contributes to establishing the history of usage. 
       FIG. 4  depicts more details of an example implementation of monitor and control a device sensitivity component  210  and sensor monitoring  310 . An aspect of the invention is described in an example scenario. Often, a computer system  112  supports I/O interface(s)  112  where user control of a devices metrics are captured or input into applications processes  142 . The device metrics may be represented in memory structures. In this example embodiment, the process begins with sensor monitoring  310 . In the example embodiment, device movement detected  405  receives information about the device input. The information is captured and stored as structured data. The structured data may be a set of data, for example, coordinates and time. For illustration purposes only, each entry is referenced as a row in a table, where the E1M1 is the first entry in row 1 for M1, E1M2 is the 2 nd  entry in row 1 for M2, . . . , continuing to E1Mn being the nth entry in row 1 for the metric Mn. Similarly, E2M1 is the first entry in the row 2 for M1, E2M2 is the 2 nd  entry in row 2 for M2, . . . , and E2Mn which is the nth entry in row 2 for Mn. This continues for all the input data, where EkM1 is the first entry in row k for M1, EkM2, is the second entry in row k for M2, . . . , continuing to EkMn which is the nth entry in row k for Mn. The metrics may be a 3D co-ordinate and time. In that case, each row would be a 3D co-ordinate (X, Y, and Z) and a time or a time ordered data. The entries may reflect changes or deltas instead of absolute co-ordinates. In any case, the input data may be converted into directional vectors to build a vector of movement  410  and store the information in cache vectors  420 . The vector of movement  410  may represent a duration of time where the first directional vector and the second directional vector are for the duration of time. The process proceeds to step  415  where vector operations may be used to determine magnitudes of vectors and answer the question: Is there a large difference between magnitudes  415 . If there is not a large magnitude difference, the process continues to detect movement  405 . If there is a large magnitude difference between the magnitudes  415 , the process continues to step  425  to answer the question: Is the first magnitude larger  425 ? If the answer to the first magnitude larger  425  question is no, then the previous vector was smaller than the current vector and the process proceeds to increase sensitivity  430  and the process proceeds to detect movement  405 . If the answer to the first magnitude larger  425  questions is yes, then the process continues to answer the question: Are vectors in opposite directions  450 ? If the answer to are the vectors in opposite directions  450  is yes, then the user has made a corrective action and the processes proceeds to decreases sensitivity  440  and then the process proceeds to detect movement  405 . If the answer to are the vectors in opposite directions  450  is no, then no corrective actions is made and the process proceeds to detect movement  405 . Adjustments to the flow would be affected by user profile  315 .
