The objects and advantages associated with the present invention can be readily understood by those skilled in the art. The following examples are intended to describe the present invention in further detail, but are not intended to limit the scope of the invention.

First, please refer to FIG. 1, which is a schematic diagram of a system architecture of a display device of the present invention. The display device 10 includes a clock signal source 11, a storage device 13, a sensor 15, a processor 17, and a display unit 19. In an embodiment of the present disclosure, the display device 10 is mounted on a shoe. display Device 10 can also be mounted, such as, but not limited to, a glove, a garment, or a handheld electronic device.

The clock source 11 is used to define the duty cycle of the display device 10. The clock source 11 can be, for example but not limited to, a quartz oscillator, an in-line quartz-free oscillating circuit, or any other device that can stably define a duty cycle.

The storage device 13 is configured to store a plurality of graphic information. The storage device 13 can be, for example but not limited to, a flash memory, a conventional hard disk, a read-only memory, or other volatile or non-volatile memory that can be used to store information.

The sensor 15 is configured to detect acceleration information received by the display device 10 and generate a set of acceleration signals according to the acceleration information. The sensor 15 can be, for example but not limited to, a single axis accelerometer, a dual axis accelerometer, a three axis accelerometer, or other device that can be used to detect acceleration information. In the embodiment of the present disclosure, a three-axis accelerometer is used as an example.

The display unit 19 is for displaying graphics. Display unit 19 can be, for example but not limited to, a liquid crystal display or a light emitting diode display. The display unit 19 can also be a touch display device.

The processor 17 is coupled to the clock signal source 11 , the storage device 13 , the sensor 15 , and the display unit 19 . The processor 17 is configured to determine the graphic displayed by the display unit 19 from the plurality of graphic information stored in the storage device 13 based on the acceleration signal generated by the sensor 15 during each duty cycle of the display device 10.

The internal components of the display device 10 and their coupling relationship have been described above, and the operation of the display device 10 will be described below. The operation of the display device 10 is described in detail below.

Please refer to Figures 2A to 2G. Fig. 2A is a timing diagram of the acceleration signal generated by the sensor 15 at a step when the display device 10 is mounted on the shoe as the wearer of the shoe walks. Figures 2B through 2G show various states of the foot in a step. In this embodiment, the sensor 15 measures the acceleration of the three axes and produces three acceleration signals. The three axial directions are: vertical axial direction (up and down), first horizontal axial direction (front and rear), and second horizontal axial direction (left and right).

Before the start of a step, the underside of the shoe 27 is completely attached to the ground and is in a state of temporary rest, as shown in Figure 2B. Since the shoe 27 is not subject to any acceleration at this time, the values of the acceleration signals in the three axial directions are all close to zero, as shown in block 21.

When the pace begins, the foot is lifted up and there is a slight forward movement, as shown in Figure 2C. Therefore, the acceleration signal corresponding to the vertical axis and the first horizontal axis starts to have a non-zero value. However, since the front end of the shoe 27 is still in contact with the ground, the overall axial offset of the shoe 27 is not significant, so the acceleration signal corresponding to the second horizontal axis remains at a value close to zero, such as block 22. Shown.

Then, the entire foot leaves the ground and continues forward and upward, as shown in Figure 2D. At this point the shoe 27 is subjected to significant upward and forward acceleration due to This has an apparent value for the acceleration signal corresponding to the vertical axis and the first horizontal axis. Since the shoes 27 are suspended, the acceleration signals corresponding to the second horizontal axis will have different degrees depending on the individual walking. The three axial acceleration signals at this time are as shown in block 23.

After that, the foot moves to the apex of the entire step, as shown in Figure 2E. At this time, the upward and forward acceleration of the shoe 27 is lowered, so that the acceleration signal values corresponding to the vertical axis and the first horizontal axis are restored to near zero. And because the shoes 27 are suspended, the acceleration signals corresponding to the second horizontal axis will have different degrees depending on the individual's walking. The three axial acceleration signals at this time are as shown in block 24.

The foot then slides down the root of the shoe 27 as shown in Figure 2F. Since the system is subjected to the positive force of the ground in an instant, the acceleration signal in the vertical axis will have a peak at this time, and due to the instantaneous force, the three axial directions of the sensor 15 will be oscillated to different degrees, so the sensing The value of the acceleration signal transmitted by the device 15 varies drastically as indicated by block 25. In block 25, it can be seen that the values of the three axial acceleration signals are oscillating at the end of the time interval.

Finally, the bottom surface of the shoe 27 is attached to the ground, which is the final state of a step, which is also the initial state of the next step, as shown in Fig. 2G. Since the shoe 27 is not subject to any acceleration at this time, the values of the acceleration signals in the three axial directions are all close to zero, as indicated by block 26.

Please return to Figure 1, based on the above analysis of the pace, incumbent At the point in time, the processor 17 can use the acceleration signal transmitted by the sensor 15 to determine which state is currently in the step and generate a status information. The processor 17 transmits one of the pieces of graphic information stored by the storage device 13 to the display unit 19 based on the status information.

In general, the plurality of status information generated at one or more steps respectively correspond to the graphic information stored by the storage device 13. Because of the mechanism of persistence of vision, an observer can observe that the graphical information is combined into a complete pattern. The complete pattern can be, for example, but not limited to, a trademark, a slogan, or a pattern set by the user.

Although the rate of travel is not constant, such as the slowest pace of walking, slightly faster when crossing a pedestrian crossing, faster when going to work, and the fastest when walking in a race or race. However, even at different travel rates, the pace is usually consistent. Accordingly, in an embodiment of the present invention, the processor 17 can determine the rate of the current step according to the status of two consecutive pictures relative to the 2B and the block 21, and the processor 17 determines the storage device 13 according to the rate of the current step. The time at which the graphic information is stored is displayed on the display unit 19.

In an embodiment of the present invention, the storage device 13 has a motion mode in addition to a plurality of graphic information. The motion mode includes an acceleration signal corresponding to each different state in a step. The sport mode also includes the height and angle of the foot in each of the different states. The processor 17 further determines the angle at which the graphic information stored by the storage device 13 is displayed on the display unit 19 according to the motion mode. The sport mode includes a preset sport mode. This preset motion mode The formula includes the preset height of the palm, the angle of the foot, and the corresponding relationship of the acceleration of the foot.

In an embodiment of the invention, the sport mode further includes a record mode. In this embodiment, the processor 17 continuously stores the acceleration signals generated by the sensor 15 in the storage device 13 to form a recorded motion mode. The processor 17 selects one of the graphic information stored in the storage device 13 according to the recorded motion mode, the preset motion mode, and the acceleration signal generated by the sensor 15 during each duty cycle of the display device 10. The processor 17 displays the selected graphic information on the display unit 19. The processor determines the angle at which the selected graphic information is displayed on the display unit 19 according to the motion modes.

In an embodiment of the present invention, in order to prevent the processor 17 from judging an error as the signal violent oscillation problem shown by the block 25 in FIG. 2A, the processor 17 can determine the pace state according to the state of each signal by the grading method. .
