3. What is Virtual Reality
âVirtual Reality is a way for humans to
visualize, manipulate and interact with
computers and extremely complex
dataâ
In âThe Silicon Mirage: The Art and Science of Virtual Realityâ (Steve
Aukstakalnis & David Blatner)
4. Types of VR
Immersive
(mouse, keyboard, screen, microphone etc)
Non-immersive
(HMD, Dataglove, 3D Mouse etc)
24. Motivação
Amplia a percepção do usuårio
Habilidade de mostrar ao usuårio informaçÔes
que nĂŁo estĂŁo presentes realmente
Auxilia usuĂĄrios a realizar tarefas reais
25. Principais componentes de um
sistema de Realidade
Aumentada
Gerador de cena
Sistema de Tracking
Display
26. Display technologies
o OpticalâSee-Trough
o Video-See-Trough
o Monitor-Based AR
o Projector-Based AR
30. Optical see-through vs. Video see-through
Vantagens do Optical see-through
Simplicidade (um stream e sem distorçÔes)
Resolução (não altera mundo real)
Segurança (falha no sistema)
AusĂȘncia de offset (eye-position)
38. ARToolKit

posicionamento e
orientação da cùmera
Objetos virtuais sĂŁo
projetados sobre os
marcadores
46. Onde pode melhorar...
