“…Our results were similar to another study by Ramsamy-Iranah et al . [ 40 ], which suggested that a larger height contrast for 3D symbols was more easily differentiated from other components by the blind. These findings reflect the need for a solution that is able to provide comprehensive medication information to BVI patients, yet simple in delivery.…”

This study explored the potential of three-dimensional printing (3DP) technology in producing a three-dimensional (3D) medication label for blind and visually impaired (BVI) patients to ease their drug administration. Different variations of label wordings, dosing instructions, and medication identifiers were designed with reference to guidelines by the American Foundation for the Blind. Shapes and symbols were used as dosing instructions and medication identifiers to the patient’s medical conditions. Prototype designs were created with common graphics computer-assisted drafting software and 3D-printed using acrylonitrile butadiene styrene as the polymer filament. Feedback was then obtained from five people with normal vision and four BVI persons. The initial prototype comprised four components, namely, medication name and strength, patient’s name, dosing instruction, and medication identifier. A revised label comprising the latter two components was developed after feedback by BVI persons. Words were in all uppercase and regular font type, with a 5-mm center-to-center letter spacing. Elevation heights of the letters alternated between 1 mm and 1.5 mm. A half sphere represented the medication dose unit, while vertical lines and a horizontal center line with alternating elevation of arrowheads represented the frequency of administration and the medication’s consumption in relation to food, respectively. Symbols based on target organs were used as medication identifiers. With rapid advancements in 3DP technologies, there is tremendous potential for producing 3D labels in patients’ medication management.

“…Ramsamy-Iranah and colleagues designed 14 tactile symbols conveying color information. Results indicated that tactile symbols on a plastic surface can be useful to facilitate color recognition for children who have visual impairment (Ramsamy-Iranah et al, 2016). In addition, a recent study by our research team attempted to express 9 representative colors (pink, red, orange, yellow, green, blue, navy, purple, and brown) using tactile grating patterns (Shin et al, 2020).…”

“…Although object outlines are crucial for comprehending artworks (Arnheim, 1990), color perception is another substantial part of art appreciation (Cho et al, 2021; Shin et al, 2020). Therefore, it is essential to establish a perceptual link between colors and texture properties (Ramsamy-Iranah et al, 2016). There have been a number of suggestions to create a one-to-one factitious link, for example, braille patterns (Brunot & Brunot, 1986; Grant et al, 2000), braille color code in interactive tactile graphics (Taras & Ertl, 2009), and vibrotactile actuators (Tapson et al, 2008).…”

We proposed a method representing relative color difference using tactile grating patterns by changing 3 components (i.e., orientation, spacing, and height) and assessed the feasibility psychophysically and qualitatively. Most color expression studies for the visually impaired have focused on a 1-to-1 correspondence between color and tactile patterns. With this 1-to-1 correspondence, a long period of associative learning is necessary, and it is impossible to represent a subtle change of colors. However, the proposed method could enable the effective perception of color changes. Two different experiments were conducted with sighted participants as a preliminary study to examine this method’s feasibility and effectiveness. In a psychophysical experiment, participants performed dissimilarity rating tasks to measure how sensitively they perceived orientation, spacing, and height-change of the grating. In a tactile art appreciation experiment, participants appreciated 3 different tactile artworks characterized by 3 different grating components and responded to the questionnaire. The grating’s orientation and spacing changes were revealed as effective in tactile dissimilarity perception and expressing color change within an artwork. However, the grating height-change was revealed as it was difficult to perceive the texture changes and had less effectiveness in expressing colors. Among the 3 components, orientation- and spacing-change of the grating were effective for expressing color changes. In addition to art appreciation, this method can be useful in many applications for the visually impaired where the effective expression of color change is required.

“…In learning, AM could be used to enhance braille learning with projects such as Tagalog and Fittle (used in the deafblind program at Perkins School for the Blind, https://www.perkins.org/; Arbes et al, 2018;Jain et al, 2018;Kleck, 2020). AM could also improve functioning in ICF domains such as "self-care" (i.e., 3D printable printlets project; Awad et al, 2020;Wong et al, 2020), "domestic life" (i.e., tagging systems for color and adaptations for appliances; Guo et al, 2017;Ramsamy-Iranah et al, 2016); and even "community, social and civic life" notably by enabling tactile adaptation of popular leisure activities and improving accessibility to art (with the tactile translation of paintings and recreation of sculptures), architecture, and cultural sites (Gabry, 2018;Karastoyanov et al, 2019;Montusiewicz et al, 2018;Rossetti et al, 2018;Voigt & Martens, 2006;Watkin, 2016). Furthermore, even though most AM studies focus on younger populations in the context of education, 3D printed models can also be useful to older people (i.e., group 3 with age-related deafblindness).…”

Applications of Additive Manufacturing, or 3D Printing, in the Rehabilitation of Individuals With Deafblindness: A Scoping Study

Additive manufacturing (AM), also known as 3D printing, is a promising tool to produce assistive technology. For instance, individuals with deafblindness (concurrent vision and hearing loss) could benefit from tactile AM-based products as touch may be their main gateway to access information. This study thus aimed to synthesize evidence on the current and potential practices involving AM in the context of deafblindness rehabilitation and to inform healthcare professionals and family caregivers on how AM can improve functioning and quality of life. A comprehensive literature search of ten databases (PsycINFO, MEDLINE, Global Health, PubMed, CINAHL, EMBASE, ERIC, Web of Science, Engineering Village, and Scopus) was performed to identify sources focusing on the use of AM toward rehabilitation goals of individuals with deafblindness. Nine of 1,397 studies met the inclusion criteria. The findings reveal that AM can counter barriers to full accessibility by enabling professionals to produce customized adapted material and communication devices, thus assisting individuals with deafblindness in communication, mobility, and learning. However, this review highlights a need for more AM research, resources, and training: interdisciplinary collaborations with AM specialists thus appear essential in improving rehabilitation services with AM.
