“…when subjects encode the environment layout independently of themselves, lead to the creation of more accurate cognitive maps (Gaunet and Thinus-Blanc, 1996). More recently, Lahav and Mioduser (2008) have found congruent results in a study in which blind people explored a multi sensory virtual environment. Using a force feedback joystick (Microsoft SideWinder), subjects used an allocentric strategy to explore the 54-square-metres room containing seven objects.…”

Nowadays, thanks to the accessibility of GPS, sighted people widely use electronic charts to navigate through different kinds of environments. In the maritime domain, it has considerably improved the precision of course control. In this domain, blind sailors can not make a compass bearing, however they are able to interact with multimodal electronic charts. Indeed, we conceived SeaTouch, a haptic (tactilekinesthetic) and auditory virtual environment that allows users to perform virtual maritime navigation without vision. In this study we attempt to assess if heading or northing "haptic" views during virtual navigation training influences non-visual spatial knowledge. After simulating a navigation session in each condition, a blind sailor truly navigated on the sea and estimated seamark bearings. We used the triangulation technique to compare the efficiency of northing and heading virtual training. The results are congruent with current knowledge about spatial frames of reference and suggest that getting lost in heading mode forces the blind sailor to coordinate his current "view" with a more global and stable representation.

“…The avatar moves in a physical workspace, depending on the haptic device, that the user explores in an exocentric way.

Experiments with VE representing real environments investigate the possibility that a preliminary virtual exploration can support the construction of an effective cognitive map, helping blind to navigate the real counterpart in a more autonomous and secure way.…”

“…Moreover, it outlines that blind users require detailed and articulated 3D virtual worlds so that it is important to find more automatic ways to create such environments. (Lahav & Mioduser, 2008) developed a 3D multimodal indoor VE that can be navigated with the Microsoft Force Feedback Joystick. They compared the performance in the real environment of people trained on the VE with those of the control group that directly explored the real one.…”

“…Naturally, the above motivations apply to all students. However, studying how blind people recognise or perceive geometrical objects has different applications, with orientation and mobility training being perhaps the most important applications for the visually impaired [12][13][14]. Orientation and mobility instruction needs to include the teaching of abstract terms such as point, line, parallel to, above, under, besides and perimeter familiarisation, all of which can be practised in a haptical virtual environment [14].…”

Research has been conducted on how to aid blind peoples' perceptions and cognition of scientific data and, specifically, on how to strengthen their background in mathematics as a means of accomplishing this goal. In search of alternate modes to vision, researchers and practitioners have studied the opportunities of haptics alone and in combination with other modes, such as audio. What is already known, and has motivated research in this area, is that touch and vision might form a common brain representation that is shared between the visual and haptic modalities and through haptics learning is active rather than passive. In spite of extensive research on haptics in the areas of psychology and neuropsychology, recent advances and rare experiences in using haptic technology have not caused a transfer from basic knowledge in the area of haptics to learning applications and practical guidelines on how to develop such applications. Thus motivated, this study investigates different haptic effects, such as free space, magnetic effects and the bounded box when blind people are given the task of recognising and manipulating classes of 3D objects with which they have varying familiarity. In parallel, this study investigates the applicability of Sjöström's guidelines on haptic applications development and uses his problem classification to capture knowledge from the experiments. The results of this study show that users can easily recognise and manipulate familiar objects, albeit with some assistance. There is an indication that users completed tasks faster and needed less assistance with magnetic effects. However, they were not as satisfied with this mode. While the results of this study show that haptics have the potential to allow students to conceptualise 3D objects, much more work is needed to exploit this technology to the fullest. Objects with higher complexity are difficult for students, and, in their opinion, the virtual objects (as presented) leave much room for improvement. Sjöström's error taxonomy proved useful, and four of five sub-guidelines tested were confirmed to be useful in this study.
