Have you ever seen those electronic yellow lines on TV football games which show the line of scrimmage and the position of the first down marker?
How about applying this technology to mundane household chores?
For example, when you vacuum. Sometime’s we forget where we vacuumed and where we didn’t. If we all had our own yellow electronic lines we could see that overlap the real surface, we could see where we have and haven’t vacuumed yet. Same thing for sweeping.
Let’s go even farther. What about farming? What if we could lay out where to sow and where to make sure we drive our tractors in a straight line? Maybe we won’t even need a tractor driver. Maybe we could sit on the side of the field and drink margaritas while our happy tractors do all the work for us.
