Exploring Geometric Shapes with Touch
"... Abstract. We propose a new technique to help users to explore geometric shapes without vision. This technique is based on a guidance using directional cues with a pin array. This is an alternative to the usual technique that consists of raising the pins corresponding to dark pixels around the cursor ..."

Geometric Shape Detection with Soundview
- In Proceedings of the International Conference on Auditory Display (ICAD
, 2004
"... We present the results of user studies that were performed on sighted people to test their ability to detect simple shapes with SoundView. SoundView is an experimental vision substitution system for the blind. Visual images are mapped onto a virtual surface with a fine-grained color dependent roughn ..."

RECTANGULAR LATTICES AS GEOMETRIC SHAPES
"... Rectangular lattices were introduced by Grätzer-Knapp [3] for planar semimod-ular lattices. This notion is an important tool by the description of planar semi-modular lattices. J(L) denotes the order of all nonzero join-irreducible elements of L and J0(K) is J(L) ∪ 0. Let X,Y be posets. The disjoi ..."

Rectangular lattices were introduced by Grätzer-Knapp [3] for planar semimod-ular lattices. This notion is an important tool by the description of planar semi-modular lattices. J(L) denotes the order of all nonzero join-irreducible elements of L and J0(K) is J(L) ∪ 0. Let X,Y be posets. The disjoint sum X+Y of X and Y is the set of all elements in X and Y considered as disjoint. The relation ≤ keeps its meaning in X and in Y, while neither x ≥ y nor x ≤ y for all x ∈ X, y ∈ Y. If R is a rectangular slim semimodular lattice then J(R) is the disjoint sum of two chains C1 and C2 wich means that that x ∈ C1, x ∈ C2 are incomparable. The width w(P) of a (finite) order P is defined to be max{n: P has an n-element antichain}. The width of J(L) is called the dimension of a semimodular lattice L and will be denoted by dim(R). An other dimension concept is Dim(L). n = Dim(L) is the greatest integer such that L contains a sublattice isomorphic to the 2n-element boolean lattice. If L is a distributive lattice then dim(L) = Dim(L). On the other hand Dim(M3) = 2 and dim(M3) = 3.
