Color reproduction with a smartphone

Abstract: The world is full of colors. Most of the colors we see around us can be created on common digital displays simply by superposing light with three different wavelengths. However, no mixture of colors can produce a fully pure color identical to a spectral color. Using a smartphone, students can investigate the main features of primary color addition and understand how colors are made on digital displays.

“…low-cost laboratories) and, on the other hand it allows the students to make measurements of physical phenomena outside the teaching laboratories, taking profit of daily activities. Different examples of the use of general purpose applications that access the smartphones sensors in students' laboratory measurements can be found in several fields of physics, as mechanics [22][23][24][25][26][27], acoustics [28][29][30], electricity [31], magnetism [32] or optics [33,34]. However, some of these free applications lack the necessary tools to assess the accuracy of their measurements or even to analyze the influence of their use in different devices.…”

“…Revista do Professor de Física, v. 4, n. 2, p. 109-129, Brasília, 2020. Outros temas cotidianos transparecem nos artigos revisados, como a caracterização de uma cor pelo seu comprimento de onda (SILVA, 2007), a inexistência de estrelas da cor verde (DIONISIO e DIONISIO, 2007) ou a coloração de pixels em telas de cristal líquido (LCD) de smartphones (THOMS et al, 2013). Entretanto, a correta identificação das cores primárias, secundárias e complementares é o mais comum dos questionamentos que os autores buscam responder em seus trabalhos, sendo a motivação principal de pesquisa na maioria dos artigos (SILVA e TOPA, 2001;NOPPARATJAMOJOMRAS et al, 2009;NAVRÁTIL, 2007;PLANINŠIČ, 2004; MOTA e SANTOS, 2014) que se dedicam a responder as perguntas típicas dos estudantes, mesmo que estas não sejam as principais motivações de pesquisa desses autores.…”

“…En la bibliografía reciente se pueden encontrar numerosas propuestas de experiencias prácticas de Física basadas en la utilización de smartphones y/o tablets como herramientas de medida en experiencias de mecánica (Kuhn y Vogt, 2012;Vogt y Kuhn, 2012a, 2012bCastro-Palacio, Velázquez-Abad, Giménez y Monsoriu, 2013;Vieyra y Vieyra, 2014;Hochberg, Gröber, Kuhn y Müller, 2014;Monteiro, Stari, Cabeza y Martí, 2015), acústica (Parolin y Pezzi, 2013;Kuhn y Vogt, 2013b;Kuhn, Vogt y Hirth, 2014;Parolin y Pezzi, 2015;González y González, 2016;Di Laccio Caceres et al, 2017) u óptica (Sitar, 2012;Thoms, Colicchia y Girwidz, 2013;Monteiro, Stari, Cabeza y Martí, 2017;Sans et al, 2017;Salinas, Giménez, Monsoriu y Castro-Palacio, 2018). Sin embargo, hasta ahora no se ha empezado a comprobar la eficacia de la utilización de smartphones y/o tablets como herramientas de medida en experiencias prácticas en el aprendizaje de la Física por parte del alumnado.…”
