Background technology
The fast development of ICT (information and communication technology) brings the fast transition of information and communication environment, and mobile communication terminal is almost used widely in the whole world, and rapid MP3 salable broadcast device in market in recent years, hand-held access terminals MID, and even Web TV instantly.
The initial network equipment, as mobile phone, the function of support and the content of management are quite limited, and simple two navigation key just can satisfy user's use needs.Along with becoming stronger day by day and organize content increasing of cell-phone function, two navigation key have developed into widely popular four-way navigation key a few days ago.
But along with the fast increase of mobile phone memory capacity, the user need browse selection in a hundreds of project.For example the user wishes to navigate to the 500th in 1000 short messages, and the visit that traditional method of operating is, is consuming time longer.Moreover in Web TV, the media file tabular that server provides has up to ten thousandly, though be to arrange by letter, still has considerable listed files in same letter, and one one of user searches still inconvenience.
In order to promote user's searching speed, in high-end handheld device such as mobile phone, adopted touch-screen, the user can directly drag the progress edge strip and carry out the rapid navigation location, the mobile phone that also has is carried and has been total to the patent roller, this is equivalent to two navigation device of the high speed that a patent uses, in TV remote controller, also have to use to fly shuttle, increase the speed of visit.Though the principle and the means of touch-screen and roller are different, the both can improve the purpose of quick visit, has all introduced new hardware device, has increased cost.
In addition, also have, make the user navigate when mobile in " long distance " by increase a pattern of quickening to move for the navigation key of standard, can fast greatly mobile speed, reduce the required time of operation, change the shirt user experience.But no matter be to set up the special-purpose button that quickens, still adopt the acceleration browse mode of setting, pin button or turnover key up and down, carry out browsing of the last one/next one and page turning, or click turn over multirow, still to a screen, its speed of browsing is all fixed.Along with money is fast abundant, the increasing of media file, as a large amount of songs, movie and television contents, the user is more and more stronger to the demand of quick location.Fixedly the mode of acceleration still can not adapt to user's request.
By telepilot equipment is operated, the mode that will speed up is set in the telepilot end, and its speed of adjustment that can not be in good time according to the quantity of current page focus, it is comparatively clumsy that accelerated mode still seems, intelligent inadequately!
Therefore, be necessary to provide a kind of method of fast browsing, to satisfy the demand that the user browses quick location.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with reaching embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In order to realize purpose of the present invention, the present invention proposes the user the time in the face of resource entries on the page or operation focus, press remote keying.The infrared receiving device of terminal is received the infrared code value that telepilot is sent, and infrared driver reads this code value, and this code value is uploaded to application program.
After application program is received, carry out a judgement, if in the short time, for example in 1 second, receive identical code value several times continuously, as 3 times, that means that the user during this period of time carries out button operation with very fast frequency, even is exactly the operation of growing by not letting go, and the time interval that continuous several times user operation is just arranged is less than preset threshold, the time interval of twice operation diminishes perhaps, i.e. Δ t
2<Δ t
1, the expression user has accelerated operating speed.
In case detect such phenomenon, application program just can think that this moment, the user did not have too big interest to current the Resources list, is eager to continue to browse downwards, and application program can be catered to this tendency intelligently, begins to carry out the operation that acceleration rolls.
The algorithm that acceleration rolls is: the initial value of acceleration is 1, if the user continues in the regular hour scope, keep button operation behavior fast, button or length are pressed fast, one period identical time interval of every mistake, as 200 milliseconds, acceleration value adds one or certain rational round values, adds down always.The speed of browsing with raising.
In every one time interval of mistake,, follow following formula to receiving the system responses of one-touch:
V
n=V
n-1±a ......(1)
Wherein, V
N-1Be last whenever by one-touch should jumping focal point number, a is an acceleration, is an integer, as gets 3, if the time interval of the operation of twice of front and back does not develop to elongated direction, gets "+" number, the V that calculates like this in the formula (1)
nTo be to increase, whenever press the number V that one-touch should jumping focal point as the last time
N-1Be 10, the focus number that should skip behind this button is 13, and promptly the number of whenever skipping by a secondary foci increases by 3, and the speed of browsing is constantly accelerated.
As being 0.2 second between preceding single job, the time interval of this operation becomes 0.5 second, and the time interval of the operation that front and back are twice obviously increases, and shows that soon near the target localization point, the user has slowed down operation, gets "-" number, the V that calculates like this in the formula (1)
nTo reduce, be convenient to the operation of user the time near target localization point.
If user's operation has one significantly to suspend, as 1 second, then system was by quickening to change common browsing into, promptly whenever by once skipping a focus.
Owing to set acceleration a, along with the increase of number of operations, the speed of system's button can be in response to the in good time adjustment of user's operating speed.
Although formula (1) has been set acceleration, but for the table listings of checking big data, particularly to visiting as list of songs, when having thousands of first songs to allow the user select, fixedly the scheme of acceleration still has inconvenience to a certain degree, the response when system wishes that to the user rapidly the purpose of location can not be fast by quick button.
Therefore, to the improvement of said fixing acceleration scheme, degree of will speed up a and user key-press speed hook:
Wherein K regulates parameter, is a fixing integer.
Then system follows following formula to the response of receiving one-touch:
Δ t
N-1Be the time interval Δ t of twice button
N-1=t
n-t
N-1, the time interval is short more, and expression user key-press speed is fast more,
Value just big more, V
nThe speed increase also fast more, can be more the quick operational requirements of catering to the user of intelligence, in general user's key scroll is fast more, the expression current location is far away from target localization point, the speed V that need increase to browse this moment
n, get in the formula (2) "+" number.
The user is near target localization point; usually can slow down key scroll; interval between this moment twice button will be elongated; be that Δ t becomes greatly; t changes from small to big if system detects Δ; just expression has been put near target localization soon, and the speed that need slow down and browse this moment is got in the formula (2) "-" number.
So, adopt the visit speed technology of formula (2), the operating speed that the in good time sound of energy reflects the user improves the speed of location.
For this kind equipment of Web TV, often the quantity of focus is a uncertain state on the page, sometimes the song choices in the list of songs has thousands of, and the quantity of focus has only dozens of in the news pages, is a fixing integer if regulate parameter K, and the parameter K value is big, visit to the big data quantity focus is comparatively suitable, and to the less situation of page focus quantity, too fast acceleration can bring the inconvenience of operation equally.
Therefore, one preferably method be to regulate parameter K can adjust dynamically with the quantity of current page focus, a scheme is
Wherein m is the quantity of focus in the current page, P is an evolution constant of default, simple proposal is to round as regulating parameter K after the quantity m with the current page focus opens 4 powers, for example there are 10000 songs selective in the current song tabulation, the adjustment parameter K gets 10 after opening 4 powers, if the focus quantity of current page is 100, opens and adjust parameter behind 4 powers and get K and get 3.The size of P also can be provided with stage by stage according to the size of m, and more than or equal to 10000, P gets 4 as m, and m is less than 10000, and P gets 3.
Also can set the parameter of adjusting a wage scale according to the quantity segmentation of focus, promptly in the focus quantity 100, the parameter of adjusting a wage scale is 1, focus quantity is regulated parameter and is established 3 between 100 to 1000, and the focus number is managed between 1000 to 10000, regulating parameter establishes 10,10000 and establishes 50 with the adjusted parameter.Purpose realizes regulating parameter exactly to be increased and increases gradually according to focus number reason.
Close the quantity of filtering the current page focus, the speed of user key-press examined eventually, system quickens to browse as follows:
So, system browses acceleration and can adjust dynamically along with the quantity of current page focus, and focus quantity m is big more, and surfing is fast more, can respond user's key scroll simultaneously in good time, and the speed of button is fast more, and the acceleration of browsing is also fast more.System more intelligence, more cater to user's operation expectation, improved locating speed, more human nature.
Because Δ t changes from small to big, and gets " one " in formula (2), (3) and can fall the speed V that browses at the end to a certain extent
n, but Δ t is big more, and the interval of twice operation just is long more,
Or
More little, as to browse speed V
nThe reduction amplitude is also more little, and this does not conform to user's operation expectation.
In order more to cater to the needs that the user is slowed down, the further improvement of the deceleration part in formula (2), (3) is as follows:
Δ t wherein
N-1Be that first is significantly greater than more previous interval of delta t
N-2, suppose Δ t
N-1Equal 0.6 second, Δ t
N-2Equal 0.15, adopt in the formula (4)
The deceleration ratio of determining 4, system reduces surfing V by 4 times speed
n, as long as the user does not have continuous quick operation, V signal for faster appears,
nSpeed can reduce significantly, then system's operation demand at heart of more meeting the user.
Be understandable that in order to reduce V faster
nSpeed, the further improvement of formula (4) is as follows:
The desirable integer of q wherein, value is big more, V
nThe range of decrease is fast more.
Be understandable that the time interval of twice operation of the quantity m of page focus and front and back can independently use, if only examine the quantity m of filter page focus, formula (3) can be changed to:
Being understandable that resource of the present invention is browsed method for changing speed, is to establish an initial velocity v starting aero mode
0, by setting initial velocity v
0, make user's operation that an initial velocity v be arranged
0, can accelerate the efficient that the user operates greatly.
Further be with initial velocity v
0With the quantity m hook of focus, so as big more at the quantity m of focus, initial velocity v
0Also corresponding the change greatly, this quantity m according to focus calculates initial velocity v with a mathematical formulae
0, perhaps set initial velocity v stage by stage according to the size of the quantity m of focus
0Size.
Be understandable that resource of the present invention is browsed the method for speed change, it quickens can to switch at any time with the process of slowing down, in the process of quickening, as long as after once time interval obviously exceed the previous time interval, i.e. Δ t
N-1Significantly greater than Δ t
N-2, then enter the decelerating phase; In like manner in the decelerating phase, the user has accelerated operation, and system has detected the condition that meets acceleration, enters boost phase again.
Further improve and be that system can also be to V
nSet a upper limit, so that V
nThe actual performance of maximal rate compliance with system is with V
nBe limited within the reasonable range.
The method for changing speed that resource of the present invention is browsed, comprehensively examine and filtered the quantity of focus in the page, the acceleration of system and the quantity of focus are linked up with, the also response to user's operating speed of combination, the induction user's of system operating speed starts to be quickened to browse, also answer user's slow-down operation, and the speed that reduction is rapidly browsed, therefore, this programme is scheme compared to existing technology, does not increase any hardware and becomes also, and remote control equipment also need not to increase special button, utilize existing four navigation keys to get final product, seem more intelligent, more humane.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
