Role of tactile contents in movie
systemsEnhances audiences enjoyment .
Conveys artistic and semantic intentions of thedirector.
Emphasize specific scenes and provides rich
impression to viewers.

Tactile movie systemThe MPEG-4 system is used to implement an enhanced
tactile movie system.
It is extended by adding a new node called TactileDisplay.
Tactile contents are represented as a greyscale video called
tactile video within the TactileDisplay node.
Gloves with vibrating motors are used to deliver tactilestimuli to users as they watch movies.

Overall system configuration

Design of the glove type tactile
displaySensations are provided by many actuators on the
gloves.
Four tactile actuators are attached to the front part of each digit of the inner glove.
It allows the rectangular tactile video to be directly mapped onto the tactile array.

The electrical system of the display consists of four key components:
1) a battery
2) a microcontroller
3) a Bluetooth communication module
4)vibrating motors
All control hardware is embedded in the glove wrist bands.
The control of the gloves is wireless which enablesunencumbered viewing.

Tactile rendering process
8/6/2019 Tactile Movies
http://slidepdf.com/reader/full/tactile-movies 15/34
The tactile device controller is connected to the tactilehardware
It translates the greyscale video representation into anarray of varying actuation intensities.
Initially, the scene descriptor provides the decoded
greyscale tactile video frame
This information typically contains the
actuation intensity of each element in the tactile array.

When the tactile array size does not match the tactile video size, re-sampling is performed .
A P WM algorithm is used to render stimuli of varyingmagnitude according to the intensities specified in the
video.
This system is customizable and can be used to drivetactile devices of varying shapes and configurations.

A tool for tactile movie authoring Ease the process of creating tactile content to
accompany audiovisual media.
A tactile video is created by drawing lines with atactile brush on a semi-transparent tactile canvas .
The cells of the tactile array are spatially mapped to this tactile video.

DISADVANTAGES
Ist person metaphor is not provided.
Tactile cues applied only to the hands.
Viewers may experience some confusion if all the
tactile cues are displayed to the hands.

CONCLUSION AND FUTURE SCOPE
Tactile enhanced movie system provides viewers with
passive, on-skin, tactile sensations synchronized withaudio-visual media.
Incorporation of 1st person metaphor.
Automatic capture of tactile media.
Development of tactile language.
