The description will be made using an example in which an exercise state of a user of the electronic device is being monitored and provided through a “Walk mate 501” program, as shown in
Referring to
Thereafter, the electronic device determines its current velocity in step 303. For example, the electronic device may detect its current velocity using a GPS receiver. As another example, the electronic device may detect the current velocity based on the step count of a user per unit time. In this embodiment, the electronic device recognizes the user's motion or lack thereof using an acceleration sensor.
Thereafter, in step 305, the electronic device displays each of the images based on the image conversion weight and the current velocity of the electronic device. For example, when the current velocity of the electronic device is “4”, the electronic device calculates the conversion rate of the first image 511 as “0.4” based on the weight “×0.1” 521 of the first image 511. Then, the electronic device displays the first image 511 from the right to the left of the display unit based on the conversion rate “0.4” of the first image 511. Also, the electronic device calculates the conversion rate of the second image 513 as “1.2” based on the weight “×0.3” 523 of the second image 513. Then, the electronic device displays the second image 513 from the right to the left of the display unit based on the conversion rate “1.2” of the second image 513. Also, the electronic device calculates the conversion rate of the third image 515 as “2” based on the weight “×0.5” 525 of the third image 515. Then, the electronic device displays the third image 515 from the right to the left of the display unit based on the conversion rate “2” of the third image 515. Also, the electronic device calculates the conversion rate of the fourth image 517 as “12” based on the weight “×3.0” 527 of the fourth image 517. Next, the electronic device displays the fourth image 517 from the right to the left of the display unit based on the conversion rate “12” of the fourth image 517.
Additionally, when it is detected that the moving direction of the electronic device has changed, the electronic device may change the conversion direction of the images. For example, while each of the images may start out displayed from the right to the left based on the image conversion weight and the current velocity of the electronic device, if the moving direction of the electronic device changes, the electronic device may change the image conversion direction to the opposite direction, i.e., from the left to the right, and display the images.
Additionally, when the current velocity of the electronic device increases, the electronic device may display an image 531 in such a manner that a first region 541 is distorted and magnified to a second region 543, the second region 543 is distorted and magnified to a third region 545, and the third region 545 is distorted and magnified to a fourth region 547, as shown in
Referring to
After the application program is operated, the electronic device determines an image conversion weight for each of the images in step 403. The image conversion weight is a parameter for determining an image conversion rate according to a user's exercise state, using characteristics by which, when the user of the electronic device walks on the road, the sky image 511 appears as if viewed farthest from the user's eyes by having the slowest conversion rate, and the road image 517 appears as if viewed closest to the user's eyes by having the fastest conversion rate. For example, as shown in
After the image conversion weight is determined, the electronic device determines the current velocity and altitude in step 405. For example, the electronic device may detect the current velocity using a GPS receiver. As another example, the electronic device may detect the current velocity based on the step count of a user per unit time. As another example, the electronic device may detect the current altitude using a pressure sensor. In this embodiment, the electronic device recognizes a user's motion or lack thereof using an acceleration sensor.
After the current velocity and altitude of the electronic device are determined, the electronic device calculates an image conversion rate and a slope of each of the images based on the current velocity and altitude in step 407. For example, when the current velocity of the electronic device is “4”, the electronic device calculates the conversion rate of the first image 511 as “0.4” based on the weight “×0.1” 521 of the first image 511, the conversion velocity of the second image 513 as “1.2” based on the weight “×0.3” 523 of the second image 513, the conversion velocity of the third image 515 as “2” based on the weight “×0.5” 525 of the third image 515, and the conversion velocity of the fourth image 517 as “12” based on the weight “×3.0” 527 of the fourth image 517.
As an example of a calculation of slope, when the altitude of the electronic device at the current time is higher than that at a previous time, the electronic device determines a first reference line 563 which has an ascending slope, as indicated by a first angle 561, compared to an imaginary reference line 559 forming a right angle with the left side 553 of the display unit 551, as shown in
Thereafter, the electronic device displays the image based on the image conversion rate and the slope in step 409. For example, the electronic device converts the first image 511 from the right to the left of the display unit based on the conversion rate “0.4” of the first image 511 and displays the converted image. Also, the electronic device converts the second image 513 from the right to the left of the display unit based on the conversion rate “1.2” of the second image 513 and displays the converted image. Also, the electronic device converts the third image 515 from the right to the left of the display unit based on the conversion rate “2” of the third image 515 and displays the converted image. Also, the electronic device converts the fourth image 517 from the right to the left of the display unit based on the conversion rate “12” of the fourth image 517 and displays the converted image. In addition, the electronic device tilts the angle of the fourth image 517 based on the first imaginary line 563, as shown in
Additionally, when it is detected that the moving direction of the electronic device has changed, the electronic device may change the conversion direction of the images. For example, while each of the images starts out converted and displayed from the right to the left based on the image conversion weight and the current velocity of the electronic device, when the moving direction of the electronic device changes, the electronic device changes the image conversion direction to the opposite direction, i.e., from the left to the right, and display the images.
Additionally, when the current velocity of the electronic device has increased compared to that at a previous time, the electronic device may display an image 531 in such a manner that a first region 541 is distorted and magnified to a second region 543, the second region 543 is distorted and magnified to a third region 545, and the third region 545 is distorted and magnified to a fourth region 547, as shown in
Additionally, when the altitude of the electronic device has increased, the electronic device may recognize that a user of the electronic device is travelling on an uphill road. Therefore, the electronic device reduces the display of the third image 515 on the display unit 571 from the first region 573 as shown in FIG. 5E(a) to the second region 575 as shown in FIG. 5E(b). On the other hand, when the altitude of the electronic device has decreased, the electronic device may recognize that the user of the electronic device is traveling on a downhill road. Therefore, the electronic device magnifies the display of the third image 515 on the display unit 571 from the second region 575 as shown in FIG. 5F(a) to the third region 577 as shown in FIG. 5F(c).
The above-described electronic device calculates the image conversion rate and the slope of each of the images based on the current velocity and altitude of the electronic device. When the current velocity or altitude of the electronic device changes sharply, the electronic device may perform an abrupt image conversion based on the change in current velocity and altitude.
More specifically, when the current velocity or altitude of the electronic device is sharply changed, the electronic device may calculate the image conversion rate and the slope of each of the images by applying Equation (1) such that the image conversion rate or the slope is non-linearly accelerated, as shown in
TC=T0;
TC=TC+ratio×(T1−TC), Equation (1)
where T0613 is an initial velocity or an initial altitude, T1615 is a current velocity or a current altitude, TC 621 is a calculated velocity or a calculated altitude, and ratio is a weight. In Equation (1), TC has an initial value equal to T0.
For example, when the weight is “0.2”, the initial velocity or the initial altitude is “5”, and the current velocity or the current altitude has abruptly increased to “10”, the electronic device uses a velocity or altitude value TC which is calculated by repeatedly applying Equation (1), rather than using the current velocity/altitude T1, i.e., “10”, which, when input in the methods of
TC=5;
TC=5+0.2×(10−5)=6;
TC=6+0.2×(10−6)=6.8;
That is, when the velocity is sharply changed from an initial velocity or altitude “5” to a current velocity or altitude “10”, the velocity value or the altitude value used in the methods of
Thus, the electronic device may calculate the image conversion rate or the slope of each of the images based on an nonlinear velocity or altitude value which is calculated using Equation 1.
In the above-described embodiment, the electronic device converts each of the images, such as the first image 511, the second image 513, the third image 515, and the fourth image 517, which are separated from one another, according to the exercise state of the user, as shown in
In another embodiment, the electronic device may divide the display unit thereof into a plurality of regions and control the dynamic appearance of data displayed in each of the plurality of regions according to the exercise state of the user thereof
As described above, by displaying each of images based on the current velocity and the altitude of the electronic device, the user of the electronic device may be intuitively provided information according to the user's current moving state.
