Diversi tra questi fenomeni sono visualizzati nel <strong>di</strong>mostratore<br />

VCL.<br />

Il VCL inoltre mostra i fenomeni <strong>del</strong> colore non connessi<br />

ad una specifica situazione spaziale (ve<strong>di</strong><br />

Figura 3). Quando deve confrontarsi con combinazioni<br />

<strong>di</strong> colori e schemi a due <strong>di</strong>mensioni, il nostro<br />

senso <strong>del</strong>la vista spesso crea ciò che comunemente<br />

vengono chiamate “illusioni ottiche”. Possiamo<br />

percepire relazioni <strong>di</strong> luminosità o <strong>di</strong>fferenze <strong>di</strong><br />

tinta che non si conformano con i colori naturali<br />

esistenti (ad es. illusione <strong>del</strong> Bianco ed illusione <strong>del</strong><br />

Diamante), o contesti spaziali che non esistono fisicamente<br />

(ad es. l’illusione <strong>di</strong> Chevreul). Possiamo<br />

anche combinare le esperienze <strong>del</strong> colore <strong>di</strong> superficie<br />

e luce. Molte <strong>di</strong> queste illusioni sono state presentate<br />

con successo in forma bi-<strong>di</strong>mensionale, e<br />

la sfida specifica all’interno <strong>del</strong> progetto VCL è stata<br />

<strong>di</strong> mostrarle in un ambiente spaziale tri-<strong>di</strong>mensionale<br />

<strong>di</strong>gitale .<br />

Problemi legati alla progettazione<br />

<strong>di</strong> <strong>di</strong>mostratore <strong>del</strong> colore interattivo<br />

Il lavoro con il progetto VCL ha rilevato numerosi<br />

problemi connessi alla riproduzione <strong>del</strong> colore in<br />

ambienti virtuali (AV) così come problemi generali<br />

concernenti il progetto <strong>di</strong> un AV. Il realismo, l’interattività<br />

e le possibilità per l’orientamento spaziale<br />

all’interno <strong>del</strong> mo<strong>del</strong>lo sono temi frequentemente<br />

<strong>di</strong>scussi nella ricerca riguardante gli AV, mentre le<br />

<strong>di</strong>fficoltà riguardanti la riproduzione <strong>del</strong> colore sottolineano<br />

il bisogno <strong>di</strong> ulteriore ricerca in questo<br />

campo. Questi temi sono oggetto <strong>di</strong> una recente<br />

<strong>di</strong>scussione <strong>di</strong> dottorato da parte <strong>del</strong>la Stahre 6 .<br />

INVITO ALLA COOPERAZIONE<br />

La versione esistente <strong>del</strong> VCL è un prototipo che al<br />

momento è in corso <strong>di</strong> valutazione da un numero<br />

<strong>di</strong> potenziali utenti provenienti da vari ambiti professionali.<br />

Speriamo <strong>di</strong> avere in futuro la possibilità<br />

that do not physically exist (e.g. Chevreul illusion).<br />

We can also mix the experiences of surface colour<br />

and light. Many of these illusions have been successfully<br />

presented in two-<strong>di</strong>mensional form, and<br />

the specific challenge within the VCL project has<br />

been to demonstrate them in a spatial <strong>di</strong>gital three<strong>di</strong>mensional<br />

environment.<br />

Problems of designing an interactive<br />

colour demonstrator<br />

The work with the VCL-project has revealed several<br />

problems connected to colour reproduction in virtual<br />

environments (VEs) as well as general problems<br />

regar<strong>di</strong>ng the design of a VE. Realism; interactivity<br />

and possibilities for spatial orientation within the<br />

mo<strong>del</strong> are issues frequently <strong>di</strong>scussed in research<br />

concerning VEs, whereas the <strong>di</strong>fficulties regar<strong>di</strong>ng<br />

colour reproduction highlight the need for further<br />

research in this field. These issues are the subject<br />

of a recent doctorate <strong>di</strong>ssertation by Stahre 6 .<br />

INVITATION TO CO-OPERATE<br />

The existing version of the VCL is a prototype which<br />

at present is being evaluated by a number of potential<br />

users from <strong>di</strong>fferent professions. We hope that<br />

we will get the possibility to continue the project<br />

and develop the VCL into a platform for showing colour<br />

research results from all over the world. Therefore<br />

we invite you all to <strong>di</strong>scussions about possible<br />

future co-operation around this project.<br />

<strong>di</strong> proseguire il progetto e sviluppare il VCL in una<br />

piattaforma per mostrare i risultati <strong>del</strong>la ricerca sul<br />

colore da ogni parte <strong>del</strong> mondo. Perciò vi invitiamo<br />

tutti alla <strong>di</strong>scussione circa una possibile collaborazione<br />

futura intorno a questo progetto.<br />
