From "Reading by Hand: The Haptic Evaluation of Artists' Books" by Gary Frost:
Are there any additional approaches that will assist evaluation of artistic works in a book format? I suggest that there is an additional topic that could propagate additional tools.
This topic is the aesthetic consequence of a work of book art in the hands of the reader where tactile qualities and features of mobility are appreciated. This is a haptic [pertaining to the technology of touch] domain where the study of touch as a mode of communication is at work. Such evaluations call up deeply embedded perceptions and sensory skills where the hands prompt the mind and where the reader’s understanding can be far removed from the intentions of the artist. .... But how can we provide effective description for a more critical experience of the corporeal book? We can lift it, open it and turn a page. Is it docile or springy on opening, solid or tentative on closing? Is there a live transmission of forces through the structure or is it crippled? What instigates the reader’s ergonomic of comprehension and how are haptic features consequential to the evaluation of book art? .... [A]ll books are art in a world of subtle and critical manual evaluation. If we could delineate it, a manual evaluation or haptic criticism would lay out a physics for book art criticism, using words.
