HAPTIC CINEMATOGRAPHY


Haptic Cinematography

◮ How to associate haptic feedback to movies ?

Mainly used with action movies

Physical events : explosions, car chases, gun shots, etc.4D cinemas

Drama, comedy, romantic movies ?

Non-diegetic e ectsMove beyond enhancement of physical events only

Diegesis : de nition

◮ Non-diegetic e ect◮ E ect whose source is neither visible on the screen nor has

been implied to be present in the action◮ Example : non-diegetic sound

◮ Narrator’s commentary◮ Mood music

Cinematographic Camera E ects

◮ Typical cameras e ects◮ Arcing◮ Traveling◮ Tilting◮ Zoom-in◮ Vertigo◮ Crane shot◮ Dutch angle

Cinematic Model

◮ Follows camera movement◮ Example with Arcing, Tilting and Zoom-in

18


Semantic Model

◮ Based on the semantic ofthe Camera E ect

◮ Crane shot→Flying away

◮ Dutch angle→Instability

◮ Arcing→Intensi cation

◮ Traveling→Crab walk

◮ Tilting→Inferiority

◮ Zoom-in→Walk forward

◮ Vertigo→Vertigo

◮ Designed with H-Studio19


User Study

◮ Objective : study of the in uence of the haptic e ects basedon camera motions on the QoE

◮ Hypothesis : New haptic e ects increases QoE◮ Variables

◮ 7 video sequences◮ 4 haptic conditions (cinematic, semantic, random, none)

◮ Measure◮ Pairwise comparison (78 couples)◮ Score computed for each model

◮ 38 participants (x̄ = 36.3, σx = 10.4)

User Study

◮ Haptic e ects enhance QoE

PRINCIPLES FOR HAPTICCINEMATOGRAPHY


Inspiration

◮ Guidelines for designing haptic e ects ?◮ Inspired from Disney’s 12 principles of animation

◮ realistic animations◮ law of physics, emotional timing, character appeal, etc.

[Thomas and Johnston, 1995] 24


Principles for haptic cinematography ?

◮ Lot of tests, demonstrations, discussion with professionals◮ Work with student in cinematography◮ H-Studio◮ Blender Foundation Movies
