Text uses any of the system's installed fonts, font sizes and colours. Each activity set can contain up to 50 frames. It is possible to link activities, so that sequence length is effectively unlimited. Activities are reasonably easy to configure. Images and sounds are selected from files.
Text is typed as needed.
There are a huge number of images and sounds that are freely available on the Internet. These can be readily used in programs like Carousel, although we have found it convenient to gather some of them together onto a CD-ROM and distribute them with the software. Another example, developed for a deaf-blind adult, has no images but uses a sequence built of sound files of people laughing. This client rarely smiles except when she is using this activity. This type of activity has also been used to create software that is age appropriate.
