What is Haptic?

• 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

5

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

4. Implementation5. Demonstration

7

Passive Haptic

• Passive Haptic– No direct interaction

8

Active Haptic

• Active Haptic– Semi-interactions– Tactile and kinesthetic

9

Types of Haptic

• Two types of Haptic Media– Linear and Non-Linear

• Linear Haptic– Sequential progression– Human touches, impacts, sounds, etc…

10

Types of Haptic

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

Framework

13

Content Creation

• Audio and Video– Standard video camera– Microphone for audio

• Three Approaches for capturing Haptic data1. Physical sensors2. Modeling tools3. Analysis of other associated media

14

Physical Sensors

• Capturing haptic surfaces– Piezoelectric resonance– Touch sensors

• Movement data– 3D robotic arm– Accelerometer– Force-torque sensors

15

Content Creation

• Audio and Video– Standard video camera– Microphone for audio

• Three Approaches for capturing Haptic data1. Physical sensors2. Modeling tools3. Analysis of other associated media

16

Modeling Tools

• Capturing 3D scenes– 3D scanner to capture objects– ZCam, depth video camera (2.5D)

• 3D Modeling tool– K-HapticModel– HAMLAT– Motion capturing

17

Content Creation

• Audio and Video– Standard video camera– Microphone for audio

• Three Approaches for capturing Haptic data1. Physical sensors2. Modeling tools3. Analysis of other associated media

18

Automatic Generation

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

19

Transmission

20

MPEG-4BIFS

• 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

21

MPEG-4 BIFS

Proposed extended BIFS nodes

22

MPEG-4BIFS

• BIFS Nodes Content– Store data gathered during Creation• Ie. Piezoelectric sensors, modeling tools

• DepthMovie Node– Identical to DepthImage– Added MovieTexture for tactile content

23

Viewing & Interaction

24

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

Demonstration

• Home Shopping Scenario

30

Demonstration

• Movie with Tactile Feeling

31

Industry

• D-Box – http://www.d-box.com– Pneumatic actuated chairs– Used for movies and simulations

32

• PHANToM Sensable Technologies– Developed by a student at MIT

Industry

33

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
