  1. Elemen multimedia User interface

  2. User Interaction • Perbedaan level dalam Interface • Pasif: hanyavisualisasi • Reaktif: interaksiterbatas (misalnya, fungsiscroll panel). • Proaktif: memilihpathataumembuatpilihan (misalnyatombol) • Reciprocal: sesuaidengankebutuhan informasi pengguna

  3. User Interaction • InteraksiModel: • Navigational: memilihuntukmenentukanmana yang harus berjalan selanjutnya • Desain: user dapatmemodifikasigayapresentasi visual(misalnyawarna) • Movie: Penggunadapatmengontrolwaktusecara global (misalnyakemampuan VCR)

  14. Madeus Video Model Dokumen Madeus • Content yang menggambarkan isi informasi dari dokumen • Actor yng mendefinisikan bagaimana dasar informasi dan konten digunakan didalam dokumen (Style information, link, etc) • Temporal untuk mensikronisasikan antar bagian dokumen • Spatial untuk menampilkan spesifikasi

  15. Madeus Video Relasi • Relasi Temporal (Allen extension) • Meets, starts, equals, during, overlaps, parmin, etc. • Relasi spasial • left-_align, right_align, center_v, center_h, etc. <Temporal> … <Relations> <start Interval1=« a » Interval2=« b » /> <meet Interval1=« b » Interval2=« d » /> … <Relations> </Temporal> <Spatial> … <Relations> <left-align Region1=« b » Region2=« d » /> … <Relations> </Spatial>
