Abstract: Technology is the main medium to spread inclusive education and reduce digital
divide in almost all domains of disability. Accessibility measures, as e.g. alternative
text, long description, often including raw table data, haptic graphics, do exist but in
many aspects do not provide a good alternative user experience. Other, more
sophisticated methods tend to be complex or expensive. We propose a new method for
blind and low vision persons (BLV) to access 3D geometrical shapes using
haptic/vibrating features of of-the-shelf mobile devices based on using a mobile
application. The application converts 3D geometrical shapes into a 3D virtual model.
The user can move the mobile device and thereby virtually explore and feel the 3D
geometrical shapes. We develop a low cost inclusive application using augmented
reality where sighted user can access objects/models visually (also using haptics if they
want) together with BLVs, who explore the 3D geometrical objects. Each 3D shapes
can be assigned with different vibration patterns and height with respect to the
geometrical shape. This approach provides an easy to implement, inexpensive and of
the shelf experimental setting for improving and augmenting the user experience in
accessing 3D geometrical shapes. The approach is also considered for experimenting in
STEM education and or other subjects using graphical representation. We expect a
broad field for ideation, experimenting and sharing to support new approaches for
accessibility and inclusive education and cooperation.
