Multi-finger touch method for adjusting car audio volume

The invention relates to a volume adjustment method for a car audio, and in particular to a method for multi-finger touch adjustment of a car audio volume.

Referring to FIG. 1 , a control panel 10 for a general car audio is displayed. The audio control panel 10 has a volume adjustment button 14 (or a button) in addition to the switch button 11 , the selection button 12 , and the channel selection button 13 . The volume adjustment knob 14 is controlled by forward and reverse rotation to adjust the output volume of the car audio.

However, since the volume adjustment knob 14 (or the button) occupies insufficient control area of the entire audio control panel 10 and is easily confused with other function buttons, when driving, if the driver wants to adjust the volume, the line of sight must be temporarily Leaving the driving path and transferring to the audio control panel 10, and then paying considerable attention to find the volume adjustment button 14 to adjust the volume, so that the volume adjustment method will disperse the driving focus and affect the driving safety. Especially when the volume of the car audio is adjusted to the button type, because there are too many function buttons on the control panel, it is easy to be confused with other function buttons, which makes it more difficult to find the volume adjustment button. Therefore, it will affect driving safety.

According to this, how can I develop a volume adjustment method for the car audio, which can To solve the above drawbacks, that is, the motivation of the invention of the present invention.

An embodiment is omitted, and the method includes: detecting the multi-finger 31, 32 touching the touch screen 21 of the touch panel, and determining whether it is a first application, as shown in FIGS. 3 and 9. Mode, if not, the volume adjustment function is not turned on, if not, the volume adjustment function is turned on; in this embodiment, the first application mode is an application having a multi-finger 31, 32 zoom-out function, and is the same as the first embodiment, No longer.

Referring to FIG. 3 and FIG. 7 , when the multi-finger 31 is detected as the first index and is moved toward the first direction 41 , the touch screen 21 displays a bar-shaped volume display unit 213 , and the movement of the first direction 41 is performed. The volume is increased in volume and the length of the volume display unit 213 is increased. In this embodiment, the first index is an example of a second index, and the first direction 41 is taken as an example.

Referring to FIGS. 7 and 8 , when the multi-finger 31 is detected as the first index and the second direction 42 is moved, the touch screen 21 displays a bar-shaped volume display unit 213 along with the second direction 42 . The amount of movement reduces the volume intensity and shortens the length of the volume display unit 213; in this embodiment, the first index is an example of a two-finger, and the second direction 42 is an example of a leftward.

Referring to FIG. 9 and FIG. 10, when the multi-finger 32 is detected as the second index and is moved to the third direction 43, the mute function is used. In this embodiment, the second index is a four-finger example. The three directions 43 are cited as the leftward example, and may of course be rightward, upward, or downward.

Referring to FIG. 10 and FIG. 11 , when the multi-finger 32 is detected as the second index and then moved to the third direction 43 , the mute function is cancelled.
