“…Aqui estão inseridas pesquisas que se propõem a entender como as pessoas percebem e avaliam o espaço, bem como sua relação com o ambiente iluminado, a partir de uma abordagem em termos psicológicos, sociais, subjetivos (Veitch, 2001;Custers et al, 2010).…”

Licenciado sob uma Licença Creative Commons Impressões qualitativas em espaços urbanos noturnos por meio de ambientes virtuais imersivos Qualitative impressions in urban spaces at night through immersive virtual environmentsÍtalo Pereira Fernandes [a] , Norberto Corrêa da Silva Moura [a] , António Aguiar Costa [b] [a] Universidade de São Paulo (USP), São Paulo, SP, Brasil [b] Instituto Superior Técnico Lisboa, Lisboa, Estremadura, Portugal ResumoPesquisas no âmbito da iluminação focam no aspecto quantitativo e físico dos efeitos lumínicos e seu desempenho na relação usuário-ambiente. Assim, estudos sobre os aspectos subjetivos da iluminação e sua influência na percepção e no usufruto do espaço são crescentes, porém existem poucos experimentos para avaliar impressões subjetivas dos ambientes noturnos. O presente artigo tem por objetivo mapear qualidades ambientais do espaço urbano localizado na cidade de João Pessoa-PB por meio do conceito de atmosfera percebida, cuja categorização de palavras descreve qualitativamente o ambiente, utilizando o ambiente virtual tridimensional como suporte para criação e avaliação de cenários noturnos. Nesse sentido, foram simulados, em realidade virtual, dois projetos de iluminação: uma paisagem noturna existente e uma proposta de intervenção como alternativa, a fim de gerar avaliações pelos usuários. Os resultados mostram que existem qualidades subjetivas diferentes nos espaços, relacionadas com questões de segurança e sociabilidade do ambiente, o que reflete a importância dessas avaliações subjetivas, e demonstram o contributo da realidade virtual como aspecto inovador nesse processo. Contribuições do artigo dizem respeito à participação coletiva no processo de projeto e aplicação da metodologia em contextos em que a iluminação é fundamental, como espaços públicos de conjuntos habitacionais.

“…In social sciences, it is used for multivariate statistical problems, for example to reduce the number of variables [13]. In lighting research specifically, PCA is often applied to investigate perception and preference [8], [10], [32]. Wang et al used PCA to study the dimensions of atmosphere perception for dynamic lighting [32].…”

An increasing number of internet-connected LED lighting fixtures and bulbs have recently become available. This development, in combination with emerging hardware and software solutions for activity recognition, establish an infrastructure for context-aware lighting. Automated lighting control could potentially provide a better user experience, increased comfort, higher productivity, and energy savings compared to static uniform illumination. The first question that comes to mind when thinking about context-aware lighting is how to determine the relevant activities and contexts. Do we need different lighting for reading a magazine and reading a book, or maybe just different lighting for reading versus talking on the phone? How do we identify the relevant situations, and what are the preferred lighting settings? In this paper we present three steps we took to answer these questions and demonstrate them via an adaptive fivechannel solid-state lighting system with continuous contextual control. We implemented a multidimensional user interface for manual control as well as an autonomous solution using wearable sensors. We enable a simple set of sensors to manipulate complicated lighting scenarios by indirectly simplifying and reducing the complexity of the sensor-lighting control space using human-derived criteria. In a preliminary user study, we estimated significant energy savings of up to 52% and showed multiple future research directions, including behavioral feedback.

“…In addition, increasing the illuminance (from 40 lx to 400 lx) resulted in a less 'tense', less 'cosy' and more 'lively' atmosphere. Custers et al 25 found a negative relation between brightness and 'cosiness'. From these findings we may conclude that systematic changes in light characteristics influence the atmosphere, and so, the affective experience of the room.…”

Affective ambiences created with lighting for older people

Current lighting technologies provide huge flexibility in creating ambiences that may be adapted to the needs of an occupant in a room. These ambiences not only satisfy visual needs, but may also improve people's well-being. This paper describes one possible application of adaptable light ambiences, namely to counteract negative mood states that older people often experience in care centres. To this end, we wanted to create a pleasant, relaxing ambience to counteract anxiousness and a pleasant, activating ambience to counteract sadness. We asked 15 (relatively young) lighting designers to create these ambiences and averaged their input to create both ambiences in a real room. Subsequently, these ambiences were evaluated with the Atmosphere questionnaire by younger and older participants. The affective connotation of the ambiences in terms of the Atmosphere dimensions was well recognized by the younger participants but significantly less so by the older people. Hence, a photo interview with older people was used to make the ambiences more appropriate for them. A final validation experiment confirmed that the affective connotation of these new ambiences was well recognized by the older people.
