Text on Screen

Text is a visual interface for language. In contrast to speech, which is linear and will usually need to be heard in full before the listener can understand the meaning, written text offers a variety of possibilities for access and use. Written text can be read thoroughly, skim through or it can be ‘scanned’ for key words or phrases. Although small-screen devices are already multimedia machines, the incorporation of text on the display will play a decisive roll as an information medium. This is probably because the transmission of information by the written word, particularly in a public setting, can be done far more discreetly than by the spoken word. (fig.1) In order for text to be clearly shown it needs to be presented on a contrasting colour to the text itself. (fig.2) The smaller the text is the darker the background needs to be in order for it to be seen clearly. (fig.3) An intricate background always makes legibility difficult. Therefore it should especially be avoided on small screen devices. (fig.4) Increasing letter spacing improves the legibility of the text on screen. (fig.5) When showing text on a background it is often best to show it in the most contrasting colour to the background, this will often be the directly opposite colour on the colour wheel.
