A Comparative Study of Remote Controls for Digital TV Receivers

Accessibility of Interactive Television and Media Experiences: Users with Disabilities Have Been Little Voiced at IMX and TVX

“…Lessiter et al [14] EuroITV'08 in the case of Seo and Jung [30], performed an analysis of usergenerated videos) involving people with disabilities. The number of participants from these studies varied between 2 and 27 (M=14.1, SD=9.8).…”

“…Epelde et al [9] presented a system architecture, based on the ISO/IEC Universal Remote Console Framework standard, to increase television accessibility, and demonstrated it with a web application for users with visual impairments and a multimodal interface with touch and speech input for users with cognitive impairments. Lessiter et al [14] evaluated the usability of three remote controls with users with sensory, physical, and cognitive impairments. Carmichael et al [7] described a reminder system based on digital television designed to assist people with mild to moderate dementia to manage their daily schedule.…”

“…For all other uses, contact the owner/author(s). people with disabilities [14,19,28] and, thus, require design that is inclusive of users with various visual, motor, hearing, and cognitive abilities. Examples include presenting visual content via non-visual modalities to viewers with visual impairments [1,17], displaying subtitles [6] and sign language interpreters for people with hearing impairments [41], and designing effective techniques for people with motor impairments to interact with television [5,14,33].…”

Issues faced by vision-impaired users of interactive TV search facilities

“…The model of interaction where dedicated buttons on the handset are used to implement individual functions, results in a dense packing of buttons onto the device with numbers in excess of fifty being common [3]. The necessarily compressed textual and iconic representations of functionality printed onto the buttons themselves and the casing are both difficult to read (particularly in the low ambient light conditions usual for TV viewing) and ambiguous, a finding supported in [8]. Guidelines for handset design have been around for some time [e.g.…”

Interação usuário-TV digital interativa: contribuições via controle remoto

“…Controles remotos para a interação usuário-TV pode apresentar um considerável número de problemas de usabilidade, como identificado por vários autores (e.g. (Darnell, 2008) (Ferscha et al, 2007) (Lessiter et al, 2008) (Omojokun et al, 2006)), inclusive em termos de problemas de acessibilidade (Epelde et al, 2009). Omojokun et al (2006) argumentam, por exemplo, problemas de interoperabilidade relacionados ao fato de um controle não ser capaz de controlar vários dispositivos, o que torna necessário que vários dispositivos estejam presentes em um ambiente de televisão; e problemas de usabilidade dado que, por exemplo, teclas que são pouco utilizadas aumentam a complexidade da interação.…”
