“…Similarly, a vast majority of respondents (87.4%) agreed at least to some extent that it is important for them to use a mainstream device that is adopted by the general public, alluding to the avoidance of tools which may work to separate users from the norm. Interestingly, prior research has found that an iPad and a portable CCTV are essentially equivalent from a functional perspective (Morrice, Johnson, Marinier, & Wittich, 2017;Wittich, Jarry, Morrice, & Johnson, 2018), suggesting that the decision to replace a traditional assistive device with a mainstream solution may be driven by reasons above and beyond functional factors.…”

Smartphones and tablets incorporate built-in accessibility features, but little is known about their impact within the visually impaired population. This study explored the use of smartphones and tablets, the degree to which they replace traditional visual aids, and factors influencing these decisions. Data were collected through an anonymous online survey targeted toward visually impaired participants above the age of 18, whom had been using a smartphone or tablet for at least three months. Among participants (n = 466), 87.4% felt that mainstream devices are replacing traditional solutions. This is especially true for object identification, navigation, requesting sighted help, listening to audiobooks, reading eBooks and optical character recognition. In these cases, at least two-thirds of respondents indicated that mainstream devices were replacing traditional tools most or all of the time. Users across all ages with higher selfreported proficiency were more likely to select a mainstream device over a traditional solution. Our results suggest that mainstream devices are frequently used amongst visually impaired adults in place of or in combination with traditional assistive aids for specific tasks; however, traditional devices are still preferable for certain tasks, including those requiring extensive typing or editing. This provides important context to designers and rehabilitation personnel in understanding the factors influencing device usage.

“…A criticism of the LuxIQ is that it has been found to have poor test‐retest reliability in assessing lighting conditions in older adults with visual impairments, 39 and to our knowledge, there have been no studies that have investigated the device’s validity. The Apple iPad is an effective assistive technology device already used by individuals with low vision 43–45 . However, previous studies have only examined the basic functionality of the iPad, and there have been no investigations looking at how the device’s display accommodations affect reading speed/ability in the visually impaired.…”

Purpose This study examined the effectiveness of the LuxIQ, the Apple iPad and a smart bulb in assessing optimal colour and illumination to facilitate reading in younger, older and visually impaired adults. Methods Participants read standardised texts at baseline (normal lighting/no device), then using the Apple iPad, LuxIQ and smart bulb, with their normal vision (20/20 condition) and using a simulated reduction in visual acuity/contrast sensitivity (20/80 condition). Visually impaired participants followed the same procedure used in the 20/80 condition. Results There was a significant interaction between condition and device in younger, F(1.5, 43.51) = 30.41, p < 0.001, ω2 = 0.34 and older, F(1.5, 4.51) = 4.51, p = 0.03, ω2 = 0.05 adults with normal vision, and there was a significant effect of device, F(2, 58) = 5.95, p = 0.004, ω2 = 0.12 in visually impaired adults. In the 20/20 condition, age and colour predicted reading speed, F(3, 176) = 36.25, p < 0.001, Adj. R2 = 0.37, whereas age, lighting and colour predicted reading speed, F(3, 176) = 36.25, p < 0.001, Adj. R2 = 0.37 in the 20/80 condition. In the visual impairment condition, lighting, colour and impairment severity predicted reading speed, F(3, 85) = 10.10, p < 0.001, Adj. R2 = 0.24. Conclusions The clinical implications of this study are that reading speeds improve in individuals with low vision under improved lighting conditions, specifically, with higher levels of luminance and colour temperature. The effectiveness of the devices varied across groups; however, the LuxIQ was the only device to improve reading speeds from baseline in older adults with visual impairments.

“…Vários dispositivos ópticos foram desenvolvidos para aumentar a independência de indivíduos com baixa visão. Dentre eles podemos citar lupas de mão ou montadas em óculos, television readers, sistemas eletrônicos portáteis de aprimoramento de visão conhecidos como Portable Electronic Vision Enhancement Systems (p-EVES) e dispositivos de reconhecimento ótico de caracteres (Wittich, Jarry, Morrice, & Johnson, 2018;Wolffsohn & Peterson, 2003;Trulaske & Meyer, 1997).…”

“…O próprio iPad (Apple, Inc) foi visto como um possível dispositivo de auxílio, devido às suas configurações (Mednick, Jaidka, Nesdole, & Bona, 2017). Entre esses dispositivos estão o Optelec Compact+, Optelec Compact 4HD, Schweizer eMAG 43 e Eschenbach Mobilux Digital sendo exemplos de p-EVES (portable electronic vision enhancement systems), sistemas eletrônicos de aprimoramento de visão portáteis (Wittich, Jarry, Morrice, & Johnson, 2018;Taylor et al, 2017). Porém, a maioria desses dispositivos ainda apresenta alto custo, com dispositivos que chegam até £545, o que dificulta a sua aquisição pelos pacientes (Bray et al, 2017).…”

A baixa visão é uma condição caracterizada pelo comprometimento visual mesmo após tratamento ou correção médica, gerando diversos impactos na vida dos indivíduos. Diante disso, a utilização de dispositivos auxiliares é fundamental para mitigar os efeitos da perda visual. Entre os diversos auxílios ópticos disponíveis atualmente, a maior parte ainda apresenta um custo elevado, o que dificulta a sua aquisição pelos pacientes. O presente trabalho teve como propósito a criação de um dispositivo óptico vestível para baixa visão, utilizando tecnologias de impressão 3D com baixo custo final. Foi realizado um estudo descritivo do tipo experimental, dividido em 7 etapas: Ideação e criação, Modelagem 3D, Impressão 3D das peças estruturais, Desenvolvimento de aplicativo próprio, Montagem, Testes e Calibração. Durante as 3 primeiras etapas criamos um suporte de cabeça para receber um smartphone e um módulo de captura e transmissão de imagens. Em seguida, foi desenvolvido um aplicativo que enviasse as imagens do módulo ao smartphone. Por fim, foi realizada a calibração do conjunto com um voluntário com baixa visão. Foi desenvolvido um dispositivo óptico vestível funcional na forma de MVP (Minimum Viable Product) que passou por testes e alguns ajustes de funcionalidade. O trabalho resultou na criação de um MVP que está sujeito a modificações industriais para seu aperfeiçoamento. No entanto, o processo de validação do dispositivo para a utilização por sujeitos de baixa visão já está em andamento pelos autores do trabalho..
