Operating method for computing devices

In combination with a computing device having a processor, memory, software, at least two button means for input engaged upon a vehicle steering wheel, and a visual display device, the method comprising:

• providing a first visual indicator on the visual display device which indicates a first function that is to be performed by the computing device if only a first button is pressed;
• providing a second visual indicator on the visual display device which indicates a second function that is to be performed by the computing device if only a second button is pressed;
• providing a third visual indicator on the visual display device which indicates a third function that is to be performed by the computing device if said first button and said second button are both pressed simultaneously;
• sensing which buttons are pressed;
• performing the first function on the computing device if the first button is pressed;
• performing the second function on the computing device if the second button is pressed;
• performing the third function on the computing device if the first button and the second button are both pressed simultaneously;
• and
• whereby said computing device can be controlled by a user while holding said steering wheel.

In combination with a computing device having a processor, memory, software, at least two button means for input, a visual display device, a grid of characters in a character screen depictable on said display device, and a curser for designating individual of said characters, the method comprising:

• providing a first visual indicator on the visual display device which indicates a first direction of motion for said curser that is to be performed by the computing device if only a first button is pressed;
• providing a second visual indicator on the visual display device which indicates a second direction of motion of said curser that is to be performed by the computing device if only a second button is pressed;
• providing a third visual indicator on the visual display device which indicates a third function of character that is to be performed by the computing device if said first button and said second button are both pressed simultaneously;
• sensing which buttons are pressed;
• performing the first function on the computing device if the first button is pressed;
• performing the second function on the computing device if the second button is pressed;
• and
• performing the third function on the computing device if the first button and the second button are both pressed simultaneously, whereby text can be input to said computing device by moving said curser with said first and second functions and designating characters of said text with said third function.
