Cool. Thanks for the links.

hi lisa,
no, I don't think so. The talking tactile pen is just a description probe that you use to access labels for the things you are touching. TTP, TTT and other devices that associate spoken description with tactile pictures are tools that improve comprehension of tactile pictures.
by the way, here are some links to our latest stuff that you may like to know about:

We are also about to release new Talking Tactile Pen museum guides for Boston Museum of Fine Arts and Smithsonian National Air and Space Museum. I will send you info about those when they are completed.

    Hi Steve,

    OK, haptic out then for the use I was thinking. But would you use
    haptic for the talking tactile pen and tactile graphic used with it?

    Thanks,

    Lisa

    Hi Lisa,

    Good question. I use the term *tactile graphic* to refer to any
    touchable image, where pictorial or spatial information is
    intended to be communicated through the pressure and abrasion of
    various materials against skin. Haptic is different and adds other
    sensory channels, such as proprioception and balance, so I only
    use that term when the whole body is involved, not just hands and
    fingers. Under *tactile graphic*, I include the various techniques
    available to designers, including raised-line and textured drawing
    (basically 2D pictures that have been outlined and accentuated
    with touchable features) and *bas-relief* (which accurately
    depicts 3D forms, but with one axis foreshortened). *Models* are
    fully 3D representations, and are probably the easiest to
    understand through touch.

    Hi,

    Again I am calling to the collective knowledge and wisdom of this
    group. My question is about what to call a tactile graphic. Hmm,
    you think, strange question after all these years and shouldn’t
    the questioner know better?

    Ok, here are the questions – is the term “tactile graphic” better
    than the term “relief graphic” ? Is the term “haptic graphic”
    better than both? Or does it not make much difference?

    By saying tactile one gives the idea that the graphic is to be
    touched, but saying relief, doesn’t necessarily. Haptic perhaps
    gives the additional information that there should be movement to
    gain information – that is the hand should move over the graphic.

    Like to hear what you think.

    Thanks,

    Lisa
