The scope of this paper is to examine the potential capabilities of embossed printers under the lens of Information Technology (IT). One of the main principles of IT is to manage and deliver information into accessible formats to all users with and without disabilities. The present study investigates the discriminability of lines and squares by…

Introduction: Many tactile graphics designed for individuals with visual impairments consider single factors. According to the results of our previous study, there may be interactions among scale, representation, and complexity factors. We conducted this integrative study with these three factors. Additionally, for the representation factor, we…

Objects such as snowflakes, castles, and butterflies have become more than just words when explored as a 3D print. The founder's passion for braille led to the creation of the program See3D, which organizes the printing and distribution of 3D printed models for people who are blind. 3D prints such as DNA, cells, animals, constellations,…

Introduction: This work investigates if simple two-dimensional (2D) tactile shapes can facilitate encoding, retention, and retrieval of associated information in the form of one-word labels. It also questions the need for the resemblance of tactile graphics with respective visual referents. Methods: Four experiments were conducted using recall…

The geologic method of stratigraphy which studies the structure of the earth by making layers was employed with 3D laser cutting techniques to make more easily defined tactile regions in templates of cells, tissues and anatomic regions containing muscles and bones. Templates were made audio responsive by hand-drilling a small hole in a template…

Educational entertainment or edutainment is a popular approach to allow learners experience a fun learning environment while acquiring knowledge. Currently, this approach is widely used and has promising benefits, whereby not only it provides a fun learning environment but also cause learners to hardly notice the learning process. However, as…

Introduction: The purpose of this study was to develop and implement an audio-tactile protocol for therapeutic intervention in individuals with visual impairments. Methods: The Physiotherapy Protocol for People with Visual Impairment (PP-PVI) was developed following five steps: physiotherapy evaluation, linguistic selection, protocol design,…

Introduction: The current work probes the effectiveness of multimodal touch screen tablet electronic devices in conveying science, technology, engineering, and mathematics graphics via vibrations and sounds to individuals who are visually impaired (i.e., blind or low vision) and compares it with similar graphics presented in an embossed format.…

The increasing use of visual diagrams in educational and work environments, and even our daily lives, has created obstacles for individuals who are blind or visually impaired to "independently" access the information they represent. Although physical tactile pictures can be created to convey the visual information, it is typically a slow,…

This study investigates responses to verbal versus tactile requests in children with congenital blindness, intellectual disability and autism spectrum disorder (ASD). Observation was conducted on two occasions. At T1, requests were given verbally, and at T2, tactile requests were given. All pupils perceived tactile symbols to be explicit requests…

Accurately aligning to a crosswalk is an important component of safe street crossing for pedestrians who are blind. Six alignment cues were evaluated in a simulated crosswalk environment in which the angle of the crosswalk was not always in line with the slope of the ramp. The effectiveness of each cue is reported and implications are discussed.…

The study reported here investigated the design and legibility of tactile thematic maps, focusing on symbolization and the comprehension of spatial patterns on the maps. The results indicate that discriminable and effective tactile thematic maps can be produced using classed data with a microcapsule paper production method. The participants…

Negative priming (NP) refers to the finding that people's responses to probe targets previously presented as prime distractors are usually slower than to unrepeated stimuli. Intriguingly, the effect sizes of tactile NP were much larger than the effect sizes for visual NP. We analyzed whether the large tactile NP effect is just a side effect of the…

Temporal order judgements (TOJ) for two tactile stimuli, one presented to the left and one to the right hand, are less precise when the hands are crossed over the midline than when the hands are uncrossed. This "crossed hand" effect has been considered as evidence for a remapping of tactile input into an external reference frame. Since late, but…

This study examined the usability of an assessment-for-learning (AfL) system that provides audio-tactile graphics for algebra content (geometric sequences) for individuals with visual impairments--two who are blind and two with low vision. It found that the system is generally usable as a mathematics AfL system. (Contains 4 tables.)
