A touch input device includes two or more interleaved scroll sensors. A common area is interposed between two of the scroll sensors. A sense line snakes through the common area. Scrolling pressure applied to a sense layer causes the sense layer to contact and electrically connect the sense line to the scroll sensors thereby permitting the scrolling pressure position to be determined by measuring a voltage on the sense line. The scroll sensors are potentiometric and may be linear strip scroll sensors or rotary ring scroll sensors. The interleaved scroll sensors with the common area allow smooth scrolling action from one major leg to another major leg.

In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. When the current position of the excavator is between the upper boundary line and the lower boundary line, a predetermined reference point of a display range is set to a predetermined position between the upper and lower boundary lines. When the current position of the excavator is above the upper boundary line, the reference point is set above the predetermined position. When the current position of the excavator is below the lower boundary line, the reference point is set below the predetermined position.

Textual content arranged in lines and displayed on the screen of electronic device is browsed by a signal processor in response to a down direction selection signal from a down button on a keypad and any links displayed in the lines in a top half of the screen are highlighted link-by-link toward a central area of the screen, wherein after the highlighting progresses to a central area of the screen, in response to further assertions of the down button, scrolling of the textual content commences, line-by-line.

Smooth animation effects during zooming are provided by retaining content displayed at a previous zoom level. If the zoom operation is a zoom out operation, new content is stretched to a current zoom level, aligned with the retained content, and placed underneath it. If the zoom operation is a zoom in operation, new content is scaled down to the current zoom level, aligned with the retained content, and displayed on top of the retained content. The new content is then zoomed with the retained content. The retained content is then deleted. When zooming out, the retained content fades out. When zooming in, the new content fades in. Smooth scrolling animation is also provided by pre-rendering a portion of content and teleporting to a final viewport position and thereby skipping over blank content.
