Some Hints by developing Multimedia Products • عدم استخدام الصوت منفردا ً دون مصاحبة بعض المواد البصرٌة. • عدم التعلٌق الصوتً على محتوى النص المكتوب ،واقتصار التعلٌق الصوتً على العناوٌن والنقاط الرئٌسة. • ال ٌجوز التعلٌق الصوتً قبل ظهور الصورة موضوع التعلٌق • عدم الجمع بٌن وسٌلتٌن بصرٌتٌن فً نفس الوقت. • استخدام التعلٌق المسموع بدل المكتوب عند عرض مجموعة من الرسوم الثابتة المتتابعة لعرض مفهوم أو مهارة ما. • إدخال النص المكتوب ٌكون فً نفس النافذة التً تعرض الرسوم المتحركة ولٌس بعٌدا ً عنها. • ربط الصور والرسوم التً تتحدث عن فكرة معٌنة أو مفهوم محدد بواسط ة خلفٌة صوتٌة واحدة غٌر متقطعة. • عند استخدام المؤثرات الصوتٌة مع التعلٌق الصوتً فالبد أن تكون هذه المؤثرات خافتة مع وضوح التعلٌق الصوتً.

Multimedia Modalities The sensory system through which a multimedia activity occurs Includes: Tactile (touch) Gustatory (taste) Visual (see) Auditory (hear) Olfactory (smell)
Based on the multimedia elements we have today, only two modalities are regularly used. Multimedia
Eng. Hani Masoud
Multimedia channels Existed within a modality E.g. channels for auditory modality are noises, speech and music E.g. channels for visual modality are words, pictures, movies.
Bandwidth? A concept of how much information can be carried by a certain channel within a certain modality. E.g. we can read at the rate of 150 words per minute which is the „printed text‟ channel within the „visual‟ modality. Much like your modem, you are unlikely to reach the theoretical maximum bandwidth of your channel within any modality, in practice.
Multimedia
Eng. Hani Masoud
Multimedia „medium‟ A set of co-ordinated channels, spanning one or more modalities, which have come to be referred to as a unitary whole, and which possess a cross-channel language of interpretation. E.g. include a television show, which typically uses the auditory and visual modalities; and picture, written text, speech and music channels.

Multimedia system characteristics Must be computer controlled All multimedia components are integrated The interface to the final user may permit interactivity Information must be presented digitally.

Types of Multimedia ď ŹLinear Multimedia ď ŹNon-linear/Interactive Multimedia
Multimedia
Eng. Hani Masoud
Types of Multimedia Linear Multimedia Users have no control over the presentation, just sit back and watches the presentation The presentation normally plays from the start to end or even loops continually to present the information. A movie is a common type of linear multimedia
Multimedia
Eng. Hani Masoud
Types of Multimedia (cont.) Interactive/Non-linear Multimedia Users dictate the flow of delivery, to control the what and
when. Users have the ability to move around or follow different path through the information presentation. Advantage: complex domain of information can be presented. Disadvantage: users might lost in the massive “information highway”. Useful for: information archive (encyclopedia), education, training and entertainment.
