What is Haptic? – There is no agreement in the precise definition among researchers. In this paper Haptic is used to define two sub- categories of feedback – Tactile – Kinesthetic 4

Motivations Broadcast programs are generally linear – A begin, middle and end Entertainment is a multi-billion industry – Consumers are actively seeking for interactive content. We have the technology – MPEG-4 BIFS (Binary Format for Scenes) – Reachin API - VRML 5

Overview 1.Introduction 2.Types of Haptic 3.Proposed Framework – Content Creation – Transmission – Viewing & Interactions 4.Implementation 5.Demonstration 6

Passive Haptic – No direct interaction 7

Active Haptic – Semi-interactions – Tactile and kinesthetic 8

Types of Haptic Two types of Haptic Media – Linear and Non-Linear Linear Haptic – Sequential progression – Human touches, impacts, sounds, etc… 9

Types of Haptic Non-linear Haptic – Interactivity, tactile information – Able to feel the surfaces – Dynamic content – Kinesthetic devices – PHANToM 10

Framework 12

Content Creation Audio and Video – Standard video camera – Microphone for audio Three Approaches for capturing Haptic data 1.Physical sensors 2.Modeling tools 3.Analysis of other associated media 13

Physical Sensors Capturing haptic surfaces – Piezoelectric resonance – Touch sensors Movement data – 3D robotic arm – Accelerometer – Force-torque sensors 14

Content Creation Audio and Video – Standard video camera – Microphone for audio Three Approaches for capturing Haptic data 1.Physical sensors 2.Modeling tools 3.Analysis of other associated media 15

Modeling Tools Capturing 3D scenes – 3D scanner to capture objects – ZCam, depth video camera (2.5D) 3D Modeling tool – K-HapticModel – HAMLAT – Motion capturing 16

Content Creation Audio and Video – Standard video camera – Microphone for audio Three Approaches for capturing Haptic data 1.Physical sensors 2.Modeling tools 3.Analysis of other associated media 17

Automatic Generation – Extract trajectory of object from video Dr. Greg Mori’s work SFU Vision and Media Lab 18

Transmission 19

MPEG-4 BIFS BIFS (Binary Format for Scenes) – Scenes are encoded and transmitted separately – Local and remote animations User  Objects interaction – Enables different points of view (3D) Scenes description – Consist of information about the objects – Time and place – Relations between the objects 20

MPEG-4 BIFS 21 Proposed extended BIFS nodes

MPEG-4 BIFS BIFS Nodes Content – Store data gathered during Creation Ie. Piezoelectric sensors, modeling tools DepthMovie Node – Identical to DepthImage – Added MovieTexture for tactile content 22

Viewing & Interaction 23

Viewing & Interaction Haptic Compositor – Route elements to renderers Haptic Renderer – Decode objects positions – Generate interaction forces Tactile Renderer – Decode tactile information – Thermal perception, intensities of tactile 24

Overview 1.Introduction 2.Types of Haptic 3.Proposed Framework – Content Creation – Transmission – Viewing & Interactions 4.Implementation 5.Demonstration 25

Implementation Implementation by the authors 26

Implementation Components – GPAC Project on Advanced Content multimedia framework BIFS Broadcaster – MPEG-4 BIFS – Darwin Streaming Server Apple's QuickTime Streaming Server Standard RTP and RTSP protocols – Osmo4 Player From GPAC framework 27

Demonstration Home Shopping Scenario 29

Demonstration Movie with Tactile Feeling 30

Industry D-Box – – Pneumatic actuated chairs – Used for movies and simulations 31

PHANToM Sensable Technologies – Developed by a student at MIT Industry 32

Conclusions Haptic Media enhances existing multimedia – Such as movies Haptic can be used in – Surgical Training – Military – Commercial Proposed Framework is feasible – Tools needed are readily available 33

That’s all That’s all folks Questions? 34
