“…This camera is supported by a battery power, always detects the objects that are against the visually impaired for a certain long distances. Then this captured image is send to the PC via wireless camera directly [1,13]. The PC has the MAT LAB programs predefined for certain specific images which are more likely to be in the outdoor environment.…”

“…For example, research into mediated social touch attempts to support touch over a distance through tactile or kinesthetic feedback (see [12] for a review). Other researchers created haptic or tactile feedback systems for a variety of purposes, ranging from increasing presence [28], expressing and interpreting emotion [3], providing spatial information to blind users [29], and encouraging users to take breaks [7].…”

Collaborative tabletop systems can employ direct touch, where people's real arms and hands manipulate objects, or indirect input, where people are represented on the table with digital embodiments. The input type and the resulting embodiment dramatically influence tabletop interaction: in particular, the touch avoidance that naturally governs people's touching and crossing behavior with physical arms is lost with digital embodiments. One result of this loss is that people are less aware of each others' arms, and less able to coordinate actions and protect personal territories. To determine whether there are strategies that can influence group interaction on shared digital tabletops, we studied augmented digital arm embodiments that provide tactile feedback or movement alterations when people touched or crossed arms. The study showed that both augmentation types changed people's behavior (people crossed less than half as often) and also changed their perception (people felt more aware of the other person's arm, and felt more awkward when touching). This work shows how groupware designers can influence people's interaction, awareness, and coordination abilities when physical constraints are absent.

“…The haptic computer interface device used (Owen et al, 2009) consisted of an electronic Braille cell (Metec AG., 2010) acting as the tactile display, mounted on a mouse case that also has four active programmable buttons (see Figure 1b). To perceive an electronically stored diagram in the computer, the "mouse" is moved over a graphics tablet (Adesso Inc., 2011: see Figure 1a).…”

“…In contrast, electronic graphics, presuming they have been effectively designed for individuals who are visually impaired, must be turned into physically created diagrams using specialized devices and/or materials before using (Edman, 1992). To avoid this intermediate step, various research groups (e.g., Owen, Petro, D'Souza, Rastogi, & Pawluk, 2009;Petit, Dufresne, Levesque, Hayward, & Trudeau, 2008;Ziat, Gapenne, Stewart, Lenay, & Bausse, 2007) have developed electronic refreshable haptic displays that directly interact with a computer to provide access to virtual tactile graphics.…”

An increasing amount of information content used in school, work, and everyday living is presented in graphical form. Unfortunately, it is difficult for people who are blind or visually impaired to access this information, especially when many diagrams are needed. One problem is that details, even in relatively simple visual diagrams, can be very difficult to perceive using touch. With manually created tactile diagrams, these details are often presented in separate diagrams which must be selected from among others. Being able to actively zoom in on an area of a single diagram so that the details can be presented at a reasonable size for exploration purposes seems a simpler approach for the user. However, directly using visual zooming methods have some limitations when used haptically. Therefore, a new zooming method is proposed to avoid these pitfalls. A preliminary experiment was performed to examine the usefulness of the algorithm compared to not using zooming. The results showed that the number of correct responses improved with the developed zooming algorithm and participants found it to be more usable than not using zooming for exploration of a floor map.
