The invention provides in the United States Patent (USP) 3,671,668 and 3,718,759 (proposing) that shows as the prior art example and improve by Reiffel.
Accompanying drawing
Fig. 1 has described the product of signal.
Fig. 2 has described to control the path of the input equipment of a cursor.
Fig. 3 has described the demonstration in the cursor path and the chaff path of a segmentation.Describe
Fig. 1 illustrates the privacy product that shows to be used to have of a data processor 71 Information system, these processor 71 signals connect 72 to display devices 81, and have letter Number connect 52 input equipments 51 to data processor. By a people handle input equipment with The control cursor movement.
Here and " signal connection " in the entire article mean the transmission of signal between the equipment that signal connects.
Input equipment sends a movable signal to data processor, and this data processor is used to produce the cursor component of a shows signal that sends to display device.This cursor component makes display device show the cursor path that the expression cursor moves.
Privacy product comprises a computer-readable signal bearing medium 11, and its signal connects 14 to data processor.This medium has chaff component 12, and it makes data processor increase a chaff component in shows signal.The chaff component makes display device show a chaff path, and it makes a people subsequently can not discern the cursor path.
Sentence " can not be discerned the cursor path " and mean that anyone can not discern the characteristic in chaff path the people who moves except the control cursor, can not discern the characteristic in cursor path, can tell chaff path and cursor path except the people of control cursor which be that anyone can not the cursor path.
Infosystem can have (sequent) input equipment 61 in succession, and its signal connects 62 to data processor, is handled this input equipment in succession by a people subsequently and moves with control cursor subsequently.Input equipment in succession sends the movable signal of a continuation to data processor, and this data processor is used to produce the cursor component of the continuation of the shows signal that sends to display device.The cursor path in succession that the cursor that the cursor component of the continuation of signal makes display device show that performance continues moves.
Here, the chaff component of medium also makes data processor increase a chaff component in succession in shows signal, makes display device show a chaff path in succession, and this path is to be discerned from the cursor path by the people.
In addition, a segmentation component 13 that can also have medium, to such an extent as to it makes the cursor component cursor component of data processor segmentation shows signal make display device display highlighting route segment and cursor route segment in succession, when an input equipment is in succession being operated.
Input equipment 51 among Fig. 2 is depicted as a computer mouse 51A, and its signal connects 52A to data processor, and moves on a mouse pad 54A.Here, mouse moves completely, towards a center, forwards the head position 22 at deep diagonal angle through 21 beginnings of the head position at diagonal angle to, again the diagonal angle turn back to and through 23 centers, towards the deep head position 24 of returning and forward to the diagonal angle at diagonal angle, center.
Fig. 3 shows a display device screen 82.On this screen, the first cursor route segment 31 of the first cursor section of moving of expression relevant 21 is together with several chafves path 31A, 31B, and 31C is shown together.In addition, the second cursor route segment 32 of the second cursor section of moving of expression relevant 22 is together with several chafves path 32A, 32B, and 32C is shown together, and the 3rd cursor route segment 33 of the 3rd cursor section of moving of expression relevant 23 is together with several chafves path 33A, and 33B is shown together.
The people of control input equipment can tell which the expression cursor section of moving in cursor route segment and the chaff path, because the correspondence between the manipulation of input equipment and the cursor route segment.People-Ta does not in succession control cursor and moves-can not distinguish the cursor route segment in the chaff path.
Symmetrically, a people in succession of an input equipment in succession of control can tell which representative cursor in succession moves in succession cursor route segment and all chaff path, because in succession input equipment operation and the correspondence between the route segment in succession.This people-not in succession cursor move carry out-can not in all chaff paths, distinguish cursor route segment in succession.
Because situation is symmetrical with respect to the exchange of " people " and " people in succession ", therefore, do not describe in succession the cursor route segment and chaff path in succession.Although described path by the segmentation component of medium by segmentation, to such an extent as to this segmentation component can be removed the cursor path can be by segmentation.This is not described, because unsegmented cursor path is that what kind of we very clear.Under the situation that does not have the segmentation component, if what described is a kind of chaotic thing, then the chaff path can generate a chaotic thing.
The demonstration in a cursor path can only be the demonstration of cursor, can be the demonstration of the circuit that moves of performance cursor, and can be the array configuration of these demonstrations.The demonstration in a chaff path can be the demonstration of chaff cursor, can be the demonstration that comprises the circuit in chaff path, and can be these combination.
In Fig. 3, the cursor of demonstration is described 41 for importing the position 86 of demonstration.Chaff cursor-the 41A that shows, 41B, 41C-are the positions 85,84,83 that will import.Have, although this people can tell that the cursor of demonstration is position of positive input, people in succession can not tell these in chaff again.
Medium can make the cursor of demonstration glimmer with identical and different speed with the chaff cursor, and can make the cursor of demonstration and chaff cursor according to a kind of relation and change shape at random.The people that the control cursor moves can control cursor flicker and alteration of form.
Cursor flicker and alteration of form in Fig. 3, have been described.Cursor 41 is circles of a flicker, the first chaff cursor 41A has changed shape to a roundlet and wink-off, the second chaff cursor 41B changes shape to a great circle and wink-off, and the 3rd chaff cursor 41C has changed shape to a less circle and opened flicker.
Sound can be followed any demonstration and all showing paths.The demonstration in the cursor path that sound is followed-comprise flicker and alteration of form-can control by controlling the people that cursor moves.Can cause sound by medium.Haptic signal corresponding to the sound of following a cursor path can make it be sent to the input equipment that the control cursor moves.
The symmetry between people and the people in succession expand to a plurality of people in succession all the pairing between symmetry.Each is through different the moving of different input device controls.Each can be controlled different cursor flicker and cursor shape through different input equipments and change.Move (and cursor flicker and alteration of form, if exist) for each, the chaff component can cause the variation in endless chaff path, cursor and the flicker of chaff cursor, and cursor and chaff cursor shape change, and these combination.
Data processor can be the data processor of a special-purpose purpose, can be the data processor of general purpose, can be independent, can be the part of network, and can be independent and a part network in the time interval that replaces.
The computer-readable signal bearing medium can be the signal of an emission, a data storage medium, and the combination of the signal of an emission and a data storage medium.
The signal of emission can be the forms of broadcasting-commonly known in the art of any various point-to-point and power transfer wireless and through wired, cable, and optical fiber.The part of signal can belong to a form that transmits, and part can belong to the second kind of form that transmits, and part can belong to the various array configurations that transmit.
