“…Deze studies laten zien dat een combinatie van informatie van verschillende zintuigen tot een completere en stabielere mentale kaart leidt. 40,[45][46][47] Praktische suggesties op basis van informatie uit verschillende zintuigen ❖ Het verkennen van een tactiel kaartje voordat iemand de echte omgeving in gaat, kan oriëntatie in de echte omgeving verbeteren. Om de informatie op de tactiele kaart echt goed te integreren in de cognitieve kaart, of om allocentrische kennis te testen, kun je tijdens het navigeren in de echte omgeving af en toe vragen om de huidige positie aan te wijzen op de tactiele kaart.…”

Het zelfstandig vinden van de weg is een van de problemen waar veel mensen met een visuele beperking tegenaan lopen. Je kan natuurlijk een begeleider meenemen, of je weg uitstippelen met een navigatie-app op je telefoon, maar voor het zelfstandig vinden van de weg is het handig als je zelf een beetje in je hoofd hebt hoe je bepaalde routes moet lopen, of hoe je bepaalde plekken, binnen of buiten, kunt vinden. Onze hersenen zijn heel goed in het opslaan van informatie uit onze omgeving. Ze kunnen een soort mentaal kaartje vormen, dat ons kan helpen om de weg te vinden. In dit artikel wil ik informatie geven over zo’n mentaal kaartje bij personen met een visuele beperking (verder in dit artikel afgekort tot PVB), onderbouwd door wetenschappelijk onderzoek, en praktische tips die eventueel gebruikt kunnen worden bij oriëntatie- en mobiliteitstrainingen.

“…Currently, the types of TEMs that can be created are tactile flashcards, tactile maps, and tactile peg puzzles, which can be developed within a few hours. It is in contrast to a development period of weeks using traditional methods such as swell paper or hot stamping [3], which are both expensive and time-consuming. Furthermore, two BVI teachers and six BVI students tested the tactile educational materials described in the mentioned paper.…”

Nowadays, users need to work simultaneously with many files and folders on their computer and various resources on the Internet, including several software pieces. It means that they have many windows open simultaneously, and they must continuously switch between different opened applications such as web browsers, text editors, or audio-visual programs. These problems are also crucial to blind or visually impaired users, for whom this issue is even more difficult. Due to the nature of their work, i.e., they do not use the mouse and cannot see the video and graphic content, they have to remember, at each moment, which programs they have open and which they no longer use. In this paper, we propose an approach that consists of universal software, where, on the one hand, the user can collect and view data; on the other hand, he can produce ready-made output packages in simple web pages. This solution consists of two main parts: an offline softwareWPad and the online - Personal Knowledge Information System (PIKS). We propose a simplified and more automated version of an earlier developed WPad software system called WPad for BVI, which visually impaired persons and other beginners can use. The solution was tested by two BVI users (one BVI student and one BVI teacher) and several non-disabled teachers and students from Poland and Slovakia. Feedback from users was collected that will be used to improve the system further.

Mental Rotation Skill Shapes Haptic Exploration Strategies

Haptic exploration strategies have been traditionally studied focusing on hand movements and neglecting how objects are moved in space. However, in daily life situations touch and movement cannot be disentangled. Furthermore, the relation between object manipulation as well as performance in haptic tasks and spatial skill is still little understood. In this study, we used iCube, a sensorized cube recording its orientation in space as well as the location of the points of contact on its faces. Participants had to explore the cube faces where little pins were positioned in varying number and count the number of pins on the faces with either even or odd number of pins. At the end of this task, they also completed a standard visual mental rotation test (MRT). Results showed that higher MRT scores were associated with better performance in the task with iCube both in term of accuracy and exploration speed and exploration strategies associated with better performance were identified. High performers tended to rotate the cube so that the explored face had the same spatial orientation (i.e., they preferentially explored the upward face and rotated iCube to explore the next face in the same orientation). They also explored less often twice the same face and were faster and more systematic in moving from one face to the next. These findings indicate that iCube could be used to infer subjects' spatial skill in a more natural and unobtrusive fashion than with standard MRTs.
