Hi Chris,

Thanks for coming up with some applications. I was really thinking in terms of line drawing, and at an abstract, implementation neutral, level. Adding some applications has made me think about this some more.

I think this comes back to my old friend serialisation. In some tasks, such as the example of establishing the distance between two points, each point can be selected in a serial manner, requiring only a single point of input to be in use at any one time. Stretching objects is an interesting example, and one where I concede that multiple points of interest could be useful. Given a situation where an object is required to be stretched to a specific size, although both points can be stretched in a non-uniform manner, multiple points of input would be advantageous. This could be achieved serially, but it would be harder. The first step would be to calculate the position of the first point, and then move that point to that position. Moving the second side is easier, and would be a case of altering the spatial relationships of the second point so that it occupied the desired distance from the first point.

Multiple input points will provide a user with the functionality of
announcing the distance between to points in millimeters, inches, miles or
kilometers (on a map), and any number of very valuable measurements that can
only be known by the application that handles the scaling and presentation.
Thus, if one is augmenting a map to their house generated by MapPoint, they
can do so with some degree of precision.  Also, if they are a kid doing a
drawing for dad they need to make sure it fits on the blank father's day
card stock that the rest of the kids are using in class.  So, I think that
having more than one point of input is very important.

Taking the whole concept from drawing into a tactile graphic system for
science and mathematics the user, with multiple input points, can, with
their hands, "stretch" a curve with far greater precision if the program
they use can provide them with x/y/z points relative to one or more other
points that they can make with spare fingers.

Hi Chris,

Whilst multiple points of input aren't necessary for drawing, the technique
typically only uses a single point of input with the other points being for
reference, I can see some benefit in multiple input points.  Sticking with
the topic of drawing, the additional input points could be used to alter
state, similar to the manner in which alt, ctrl, shift, etc. alter state on
a keyboard.  This would allow someone to use the same finger motion, or
motion of an input device, to semantically indicate different actions based
on the state of the system, determined by other input points.

Whilst not necessary, multiple input points do make for an interesting
addition, and therefore Apple could potentially deny people the opportunity
to explore these possibilities, as they have attempted to do with
possibilities in the past.  Is the LPF still active?  If so, you may have
found another convert.

Apple has recently announced that they have filed for a patent on a
multi-point touch screen which can probably solve half of the problem by
providing multiple simultaneous hot spots.  As far as reasonably priced
tactile output is concerned, there is a group called orbital (I think) doing
some very interesting work which, I hear, has come a long way since I saw it
a few years ago.  If one can "marry" these technologies, full page
interactive Braille and graphics might be possible in a profitable product
that could sell for under $1500.  I think we're at least three years out
before this can be a reality but adding touch input to tactile output (both
technologies are flexible and neither seems entirely incompatible with the
other) might not have the financial backing to move it forward.

Apple, in spite of their meager screen reader, isn't too friendly too blind
people or technologies related to blindness but they do love licensing
patents and a multipoint touch technology can find homes well beyond
anything they care to do.  Orbital is small, venture funded and very
aggressive so they want to license things everywhere.

Hey there to all,

My dream machine would also incorporate a touch tablet feature for
input and tactual output, where we could draw lines, select areas for
fills, and so on, by touching spots with fingertips, and then, well,
doing something to signal that a point-and-click should occur.

It should also allow for erasures, or slight re-draws, if finger-drawn
input hasn't been to one's exact liking.
