4.8 RECOMMENDATION FOR FUTURE WORK
The recommendation for future work of aircraft cabin simulator as follows:
• Turbulence
effect: The turbulence effect of the current aircraft cabin simulator
is caused by human force. When the simulator is above the floor, the
simulator operator will shake the simulator to create the turbulence effect.
We recommend a rotary type electric motor to be installed in aircraft
cabin simulator to create the turbulence effect automatically. The turbulence
effect can be correlated with the visual effect from the beamer. •
Floor space: The current aircraft cabin simulator occupies half of the floor
space in Simulation Lab at Main Building of Eindhoven University of
Technology. The floor space constraints in Simulation Lab caused some
limitations during the early design stage of aircraft cabin simulator, such as
the limited movement of the simulator, limited space in the aircraft cabin
simulator, small control area and narrow projection area. Wider floor space
is needed for future aircraft simulator design.
• Sound
proof and pressurized environment: The developed aircraft cabin simulator
was built with wood and medium density fiberboard material. We
recommend the simulator should be built with aluminum material, installed
with sound absorption material and using soundproof rubber seals at
the gaps between walls. We also recommend the simulator should be pressurized
to create real flight environment. •
Coordination between simulator motion and video: We recommend the
simulator motion such as taxiing, take off and descending to be coordinated
with video automatically. With the coordination between motion and video,
the simulation effect can be improved.
4.9 SUMMARY
The aircraft cabin simulator was designed with the systematic total design
approach. The total design method was useful for the development of the aircraft
cabin simulator from concept to complete buildup. The market survey, design
127 knowledge
and design experience were important inputs for the development of the
aircraft cabin simulator. Product requirement provided the designer a way to keep
track in ongoing project. The morphological chart helped the designer to identify
the various design solutions and product functions in a systematic way. The
weighted objective method was used in the brainstorming and mind mapping sessions
to generate and determine the final concept. The final aircraft cabin consists
of a control section, an inventory section, a projection section and an aircraft
cabin simulator with motion platform. Two experiments were conducted to
validate the aircraft cabin simulator. The aircraft cabin simulator was validated with
twelve participants for a 10 hours simulated flight. The presence questionnaire
was used to examine the perceived realism of the developed aircraft
cabin simulator. The statistical result showed that the developed aircraft cabin
simulator can sufficiently simulate an economy class aircraft cabin.

A SMART NECK SUPPORT SYSTEM

5.1 INTRODUCTION
The previous chapter presented the development of the smart neck support
system SnS
2
and the aircraft cabin simulator. In Chapter 3, the design of the developed
SnS
2
was described. In Chapter 5
1
, two experiments, namely a
calibration experiment and a validation experiment, were designed to evaluate
the developed system. Electromyography EMG method was used to measure
sternocleidomastoid SCM muscle stress. In order to objectify the EMG value of
SCM muscle at a pre‐defined head rotation angle, the calibration experiment was
carried out. The calibration experiment was conducted to find the relationship
between defined head rotation angle, gender, duration and the SCM EMG value.
