“…It was also expected that the time to identify an object using the magnetic effect and the bounded box would be longer. In a study by Jay et al [56], similar to the one described in this article, a magnetic effect is used to guide users around an object, and a spring is used to guide them from one node to the next. It was noticed by Jay et al that, in experiments with different haptic and auditory cues, asking blindfolded sighted users to identify structures of spheres and cubes, the authors find that haptic cues aid in structure recognition but that audio cues do not.…”

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.

“…Improving the haptic visualization of network charts therefore implies improving these two tasks. In that respect, Jay et al [112] developed some guidance interactions to improve the "recognition of abstract data at both the micro (individual nodes) and macro (overall structure) level". They used a spring force to guide the user to the leftmost node and a force constraint to keep the user on the surface of the object while he/she explores it.…”

Abstract-There are many different uses for haptics, such as training medical practitioners, teleoperation or navigation of virtual environments. This review focuses on haptic methods that display data. The hypothesis is that, haptic devices can be used to present information, and consequently the user gains quantitative, qualitative or holistic knowledge about the presented data. Not only is this useful for users who are blind or partially sighted (who can feel line graphs, for instance), but the haptic modality can be used alongside other modalities, to increase the amount of variables being presented, or to duplicate some variables to reinforce the presentation. Over the last twenty years a significant amount of research has been done in haptic data presentation; e.g. researchers have developed force-feedback line-graphs, bar-charts and other forms of haptic representations. However, previous research is published in different conferences and journals, with different application emphases. This article gathers and collates these various designs to provide a comprehensive review of designs for haptic data visualization. The designs are classified by their representation: Charts, Maps, Signs, Networks, Diagrams, Images and Tables. This review provides a comprehensive reference for researchers and learners, and highlights areas for further research.

“…Since these are single point contact devices, perception of graphic is memory intensive as the user is required to integrate temporally varying cues in order to build up an impression of the scene [55]. Jay et al [56] investigated the comprehension of abstract data at microlevel for individual nodes and at macrolevel for overall structure through guided interactions using 3-D force feedback PHANTOM device. These consisted of four unconnected geometrical objects such as spheres and cubes.…”

One of the major barriers for the social inclusion of blind persons is the limited access to graphics-based learning resources which are highly vision oriented. This paper presents a cost-effective tool which facilitates comprehension and creation of virtual directed graphs, such as flowcharts, using alternate modalities of audio and touch. It provides a physically accessible virtual spatial workspace and multimodal interface to non-visually represent directed graphs in interactive manner. The concept of spatial query is used to aid exploration and mental visualization through audio and tactile feedback. A unique aspect of the tool, named DiGVis, offers compatible representations of directed graphs for the sighted and non-sighted persons. A study with 28 visually challenged subjects indicates that the tool facilitates comprehension of layout and directional connectivity of elements in a virtual diagram. Further, in a pilot study, blind persons could independently comprehend a virtual flowchart layout and its logical steps. They were also able to create the flowchart data without sighted assistance using DiGVis. A comparison with sighted subjects using DiGVis for similar task demonstrates the effectiveness of the technique for inclusive education.
