Multimedia Presentation Effects for Immersion

DESCRIPTION

This study explores the impact of various multimedia presentation channels on user immersion. Investigated channels include dynamic visuals, audio, and tactile stimuli (vibration and air pressure). A test scenario simulating a train arrival was utilized, where participants experienced 15 different scenes. Key findings indicate that higher immersion correlates with increased media involvement, realistic situational mapping is vital, preferences differ by gender, and high-quality audio significantly enhances the immersion experience.

Presentation Transcript

  1. Multimedia Presentation Effects for Immersion Prof. dr. G.W.Matthias RauterbergIPO, Center for User-System InteractionTechnical University of Eindhoven, The Netherlands [g.w.m.rauterberg@tue.nl] ing. Fabian Honegger Onaras Inc., Switzerland [honegger@onaras.ch]

  2. OBJECTIVE To investigate the contribution of different presentation media for getting people immersed into a scene. =============================Presentation media investigated:* dynamic visual channel* dynamic audio channel* dynamic tactile channel - vibration - air pressure

  3. Test scenario: “sitting and waiting on a station platform while on the next track (in ca 20 m distance) a train enters and passes the station from left to right” Stimuli material [see E. Stahl (1997) PhD Thesis, ETH No. 12321]: recorded data for 10 seconds in total video: 1024*768 pixel, 250 ANSI lumen, PAL S-VHS audio: DAT records SONY PCM-2500, HPS-III, HEAD acoustics vibration: Vibrator type GWV46, Gearing & Watson Electronic Inc. [5 - 2000 Hz, 1 m/s2 acceleration] draught: ordinary table fan, ca 100 cubic feet per minute (cfm)

  4. Experimental Setup screen Scene left photo Scene right photo 40° viewing angle Silent chamber (Model 403-A special of IAC; size of 9.5 m2= 2.2m * 4.3m; extra shock proof) “steel girder” mock-up “ticket machine” mock-up chair slider fan headset Entrance door video projector

  5. Screen [2.1m*1.6m] scale slider right view of the scene left view of the scene Chair with vibration

  6. The chair with vibration feedback [5 - 2000 Hz]

  7. Measurement of immersion via the scale slider Measurement range: 0 - 10’000

  8. The control room

  9. Test design: 12 female and 12 male test subjects (N=24) (average age: 27 years, 17-54 range) Four independent variables: (1) vision, (2) sound, (3) vibration, (4) draught Each variable had two values: ON/OFF Sixteen possible combinations: 24=16 - 1 {all OFF} = 15 All different 15 scenes with at least one presentation media ON are randomly presented to each test subject. Total sample size: 24 * 15 = 360

  10. Statistical results SIG SIG SIG (SIG) (SIG)

  11. “What was the most realistic scene?”

  12. Conclusions: • the more media involved, the bigger immersion • a mapping to a real situation is more important, than just adding different media (e.g. “tunnel”) • women have different preferences than men • high quality audio had the most important contribution
