As data compression grows, users are able to carry more and more data in portable devices. In addition, the data can be in a variety of forms. However, portable devices are small, including having small input devices. Trying to maneuver through long lists of data becomes increasing difficult and frustrating to users.
A method of navigating items on a display on a computing device with a touch sensitive input device is disclosed. An input may be accepted at a first location on the input device and a deadzone may be created around the first location. If the input moves outside of the deadzone, a location at which the input leaves the deadzone may be stored. An input direction may be determined by using a direction from a first location to a current location. If the input moves a number of tick distances wherein the number of tick distances is greater than o, the display of items may be rotated by a factor of the number of tick distances in the input direction. If the input is removed from the device and the velocity of the input movement is above a threhold, the items on the display may be displayed in a manner in which the items rotate past on the display in the input direction at an initial velocity that decreases and in which the initial velocity is in relation to the velocity of the input movement. Similar to a bike wheel, the list of items will rotate in relation to the velocity of the input applied including speed up, slow down, stop and change directions.
a, 2b and 2c are illustrations of a portable computing device displaying items where the items move in response to user inputs;

At block 300, the input device 116 may accept an input 405 at a first location 410 on the input device 116. The input 405 may be a touch of a finger or from a stylus or any other manner of creating an input 405 on the touch input device 116. At block 310, a deadzone 420 may be created around the current location 410. The deadzone 420 is a zone surrounding the current location 410. In one embodiment, the zone is of a size such that unintentional shifting on the input device 116 is not considered leaving the deadzone 420. The deadzone 420 allows a user to make small input 405 moves without unintentionally activating undesired action. In one embodiment, the size of the deadzone 420 is 50% of the area surrounding the current location 410. Of course, other deadzone 420 sizes are possible. In addition, the size of the deadzone 420 may be adjusted by the user or by applications on the device.
At block 320, if the input 405 moves outside of the deadzone 420, a location at which the input 405 leaves the deadzone is stored in a memory 111.
At block 330, an input direction may be determined by using a direction from a previous location 410 to a current location 520. For example, the current location 520 may the first location and the previous location 410 may be the location at which the input left the deadzone 500. A vector may be created that connects the current location 520 and the previous location 410. This vector may be used to determine if the user desires to move up through a list of items, down through a list of items, of traverse in virtually any direction through a list of items when a variety of directions are enabled. For example, in a two dimensional list where movement is either up or down through a list, the motion across the input device 116 which primarily moves left to right but also move a bit upward (such as in
At block 340, if the input 405 moves at least one number of tick distances, the display of items on the display may be rotated by a factor of the number of tick distances in the input direction from block 330. In some embodiments, the factor is one, but other factors are possible. Referring to
Once an input 405 moves a tick distance 630, the items 115 on the display may be rotated by a factor of the number of tick distances 630 in the input direction from block 330. The moving of a tick distance 630 may be indicated by a notification to the user, such as a click sound or a brief shake of the device using haptic feedback. Of course, other feedback is possible and is contemplated. Referring to
At block 350, if the input 405 leaves the input device 116, a variety of things may occur and control may pass to block 360. If the input 405 stays on the input device 116, the method may return to block 340.
At block 360, a determination is made whether the the velocity of the input 405 movement is above a threshold. The velocity may be determined in a variety of ways. As is known, velocity is determined by dividing distance by time. In one embodiment, the velocity is determined by using a location of the input 405 at sampled times and the distance the input traveled during the sampled times is used to determine the velocity. In another embodiment where tick lines are used, a plurality of times that the input crossed a plurality of tick lines is used and the distance the input traveled over the tick lines is used to determine the velocity. In another embodiment, the time the input 405 left the deadzone 420 and the location of leaving the deadzone 500 is stored. Next, the time the input 405 left the perimeter 510 of the input device 116 and the location at which the input 405 left the perimeter 510 of the input device 116 is stored. The two times are subtracted and the distance is determine between the location of leaving the deadzone 500 and location at which the input 405 left the perimeter 510 of the input device 116. From this data, the velocity of the input 405 may be determined. Of course, other manners of calculating velocity are possible. The threshold may be any velocity. Control may pass to block 370
At block 370, the items 115 on the display 114 may be displayed in a manner in which the items rotate past on the display 114 in the input direction at an initial velocity that decreases and in which the initial velocity is in relation to the velocity of the input 405 movement. At a high level, the item 115 may be songs and the songs may rotate sequentially through the display 114 like a bicycle wheel turning with the songs being on the wheel. The speed of a spinning bicycle wheel relates to the velocity of the force applied to the wheel and the wheel eventually slows down. The wheel may slow faster if brakes are applied or may stop altogether if the brakes are applied very hard. In addition, a force applied to a bicycle wheel in the opposite direction in which it is spinning will not immediately bring the wheel up to a high velocity in the opposite direction but will slowly start the wheel spinning in the direction of the force.
Similarly, the items 115 may rotate through the display 114 at a velocity in relation to the velocity of the input 405. A fast input 405, i.e., a fast swipe across the input device 116, may result in a fast rotation of the item 115 list. Similarly, a slow input 405 may result in a slow rotation of the item 115 list. Threshold may be set and input 405 over a threshold may result in the maximum velocity being created.
The velocity also may relate to the number of items 115 in the list. If a number of items 115 is above an item limit, the velocity of rotating the items 115 may be greater and if the number of items 115 is below the item limit, the velocity may be lower. For example, the velocity through a 3,000 song list will be faster than rotating through a 10 song list even though a swipe input 405 of the same velocity may be applied in each case.
In addition, once the list is rotating, subsequent inputs 405 may have a variety of outcomes. Referring to
If the subsequent input 520 extends beyond the hold period of time, the rotation of the items 115 may be slowed further. In effect, if a user inputs 405 for a time longer than the hold period, the rolling of the items 115 will slow similar to grabbing and holding the brakes on a bicycle.
If there is an input 405 out of the new deadzone 530 before an expiration of the hold period of time and the input 405 is a tick length 630, the display of items 115 may be rotated by a factor in the input direction for each tick length 630 passed. In addition, the rotation of the items 115 may stop after moving the tick length 630.
If the input 405 passes the perimeter 510 of the input device 116 and if the input 405 is in a direction of the current item 115 rotation, the velocity of the rotation may be increased. Similar to applying more force to a spinning wheel in the same direction, the velocity of the wheel and the velocity of the list 115 rotation will increase. If the input 405 is in a direction opposite the current item rotation, the items may be rotated in the direction of the input at a velocity in relation to the velocity of the motion and the velocity at which the items 115 were moving before the input 405. Similar to applying pressure to a spinning wheel in the opposite direction, the wheel may slow, stop or spin in the opposite direction depending on the velocity of the force. The rotation of the items 115 may respond in a similar manner. For example, if the items 115 are is spinning forward at 10 songs per second and a swipe input 305 is applied in the opposite direction at 20 songs per second, the result may be going in the opposite direction at 3 songs per second. Also similar to a bike wheel, when the velocity of the rotating items 115 falls below a threshold, the list of items 115 will stop rotating.
The result of the method is that long lists can be quickly scanned with simple and intuitive movement. By incorporating the concept of a wheel into scrolling through a list of items 115, input movements become intuitive to users. As a result, users can navigate through lists of songs, photos, games, telephone numbers—virtually any list—in an improved manner.
