6.2 Concept Development
Twin Premier is a lounge like concept that has two first-class seating inspired from aircraft. The main concept is derived from Vehicle Lounge and combines conceptual features from Railway Platform and Partitioned Sharing into one single concept. The first class environment is from Vehicle Lounge, the modular interior features from the Railway platform and the partition at the center is from Parti- tioned Sharing. The combination of these concepts creates a comfortable lounge-like experience that provides individualized semi-private environment. The combined ideas have similar characteristics, having a flexible interior, and using simple technologies for manufacturability.
Each passenger has ample and customizable private space. The seats can be adjusted forward, backward and tilted. The office-like table can move forward and backward and the interactive partition can be removed when needed. The partition (figure 26), surround display (figure 29), and footing dis- play (figure 28) shows necessary information to the passenger using a cloud network. It is a ‘individu- alized/customizable’ interior that adds features relating to the trend of ‘On/Off Mix’. Figures 25 and 26 shows the interior modes as well as the exterior design. Figure 25, illustrates the different modules, seats and the desk, working together to form customized environments. Figure 26 shows an interactive partition, that is used for working, socializing and relaxing using the cloud network.

6.3 Final Interior
The interior showcases a possibility for autonomous vehicles. Pure EVs don’t have an engine nor a transmission that eats into the interior space. Designers are free to make full use of this additional space that makes the car more aesthetically pleasing and useable to the user.
The layout is arranged so that two passengers can enjoy their space and time inside a relatively small vehicle. Therefore the seats are arranged facing each other with a moveable partition that gives a semi-private feeling in the cabin. By arranging it face-to-face, slightly diagonal layout, passengers can have additional shoulder room as shown in figure 27.

Figure 27 is an initial photoshop sketch that illustrates how the seats and the tables are arranged.
The center dividing line is slightly diagonal that gives more shoulder room in a limited area. The diag- onal layout also has a surrounding effect for the passenger making them feel more snug inside the cabin.

Figure 28 is a developed sketch from Figure 27 but still retains the main interior layout features.
The seat was redesigned, inspired from Shrimp chair from (LAUB, 2011), making them larger and cozier. The floor graphics was reshaped to surround each passenger. The footing display can indicate various functions of the vehicle and the environment. Figures 29 to 31, shows the top view of the interior highlighting the diagonal shape and rails.

Figure 30. Diagonal layout of Twin Premier
Figure 30 highlights the diagonal layout of the interior. The diagonal arrangement allows more passenger shoulder room in a compact exterior form. Adequate space is obtained for the chairs and footrests to slide forward and backward along the rails as pointed out in figure 31. The usage of wood material, seat design with other elements gives an airy lounge feel to the cabin.

The combination of different moving interior components allows a diverse user experience.
Each interior component relates to the researched 5 trends seamlessly, explained below:
Lounge chair: Fully adjustable chair that can tilt, rotate and slide forwards and backwards for the individualization of each passenger. (Customization/ Individualization)
Foot rest: Interior component which the passenger can stretch his legs on. When there are more than two passengers, it acts as a seat. Foot rest slides forward and backward along the floor rail, and can be put away out of reach, below the table. (Customization/ Individualization)
Center partition: Interactive partition which divides the two passengers for semi-privacy. It can be folded away for socialization or for an airier cabin experience. A display is integrated into the partition that connects with the passenger’s cloud to display information to passengers.
(On/Off Mix)
Desk: Located at the front of each passenger, which the passenger can use for various activities.
When there are more than two passengers, the desk can be customized and rotated to reveal a backrest, which with footrest becomes an additional chair. (Customization/ Individualization) Floor rail: Rail that is integrated with the EV chassis of the vehicle for individualization/ cus- tomization of space. For Twin Premier, lounge chair and foot rest can move along the rail providing a flexible moving interior. (Customization/ Individualization)
Surround display: A curved display unit that is located at the front and rear of the vehicle inte- rior. It can set the mood of the car as well as display necessary user information such as time, schedule, destination, etc. (On/Off Mix)
In Social mode, the lounge chairs rotate, and the center partition folds away allowing the pas- sengers to face each other without any obstacle. The desk and the footrest work together become a temporary chair for an additional passenger. Figure 32 (left) shows a scenario where three passengers are having a conversation. Figure 34 shows how the desk rotates to become a temporary seat.

In Office mode, the lounge chair slides forward close to the table for office work. The foot rest slides even further beneath the table to provide ample foot space for the worker. Figure 32 (right) shows the passengers working inside the vehicle environment. While one passenger works with the computer, the other two passengers are having a meeting.
In Relax mode, the lounge chair tilts and stretches while the foot rest slides to support the pas- sengers legs. The center partition closes to provide a semi-private area for relaxation. The display image changes to a relaxing imagery for the most comfortable experience. Figure 33 illustrates Relax mode visually.
6.4 Final Exterior
Much of the basic exterior form is defined by the interior layout of Twin Premier, where two passengers face each other. Figure 35 is the blueprint of Twin Premier.
Figure 35. Twin Premier side blueprint
Figure 35 shows the battery located at the bottom of the vehicle and the motors located inside the wheels for space efficiency. The two passengers face each other with ample headroom.
Figure 36. Solidworks model with dummy model
Figure 36 shows the Dummy models, height of 180cm, being placed inside the 3D model to verify the size of the vehicle. The model clearly has enough headroom for the passengers and enough shoulder room. Figure 37 shows the exterior of Twin Premier in 3D modeling. The modeling by Solid- works was rendered using Keyshot Luxion with photoshop modification.
Figure 38 and 39 illustrates how the trunk and the doors operate. The shape of the trunk is not of a box shape because of the space needed for the interior foot rest. When the passenger enters the vehicle, the doors slide sideways and the lounge chair rotates. The side skirts of the car is also a display that reminds the passengers of vehicle information such as trunk openings, welcoming, battery level, etc. It can connect and display online information, such as temperature, weather and other various in- formation (On/Off Mix).

DISCUSSION & CONCLUSION
7.1 Discussion 7.2 Conclusion
7. DISSCUSION & CONCLUSION
7.1 Discussion
7.1.1 Impact of Design
This paper put forth research outputs such as future trend, mobility groups, future scenario, design requirements. From this it has examined a new type of mobility thorough ideation on mobility and with 3 Future Scenarios.
The research output may have impact, not only on mobility, but also on product and other as- pects of design. The numerous keywords and groupings found can be used as an inspiration for product design, service design and so on. Five Future Trends as a keyword for design development for any project, would help steer it into the right direction. Future Scenario, although based upon mobility, will give designers a glimpse of what to expect in the future.
The mobility design, Twin Premier, may have impact on the future outlook of autonomous vehicles. This paper has suggested a different type of mobility for 2, at most 4 passengers. It has a radically different interior layout made possible by electrification. The concept illustrates a flexible interior with a combination of moving interior components that can react to changing situations. It shows a radical change in which users can have the possibility to experience more inside the cabin.
7.1.2 Opportunity Seeking Approach
Electrification of vehicles has opened up new possibilities of design. Therefore, instead of prob- lem solving research, new opportunities and ideas were sought out that were relevant with the future context. There was adequate desktop research on the future context, followed by ideation which opened new doors to mobility design.
7.1.3 Limitations
Although the research was based upon Future Trends based on Desktop Research, the ideation used to seek new opportunities makes exploration very subjective. However it is from this subjective approach designers can have ample degree of freedom and therefore a more likely chance of a creative outcome.
Although the concept is derived from future research and their relevant contexts it has not been yet evaluated by the public. It would be assuring to conduct an evaluation survey with people outside
the project, to know their satisfaction and their thoughts upon the project. With this knowledge, the project could be further improvised for development.
Another minor limitation comes from the use of relevant modelling software during concept development phase. It is more convenient to create 3D models of complex designs with surface model- ing, aka Alias.
7.2 Conclusion
7.2.1 Project Summary
The project started with desktop research, to ideation, to concept development and to final mock-up. The paper first found 5 Future Trends which led to 2 different future studies. The first study being the 6 Mobility Groups and the second study being the 3 Future Scenarios. 6 Mobility Groups was an organization of current mobility concepts by Future Trend which helped to see the current market of future concepts. 3 Future Scenarios was an idea driven process based upon Future Trend research. The scenarios allowed for better visualization of the future context in depth and in the process, mobility concepts were ideated.
3 Future Senses were identified by combining the 6 Mobility Groups and the Concepts from Scenarios: Distinct Drive, Modularity and Moving Interior & Space. For each Future Sense, there were mobility ideas which were combined to make 4 different Concepts. From this one concept, Twin Prem- ier, to be developed in detail.
7.2.2 Expected contribution
There have been many future mobility concepts from different designers and companies. How- ever, there is little instance where these concepts are organized in a few keyword requirements. This paper identifies the requirements, 3 future senses, that summarize the different types and directions of existing mobility concepts. It is expected that the 3 Future Senses findings can accelerate the ideation process efficiently with diverse concepts. However, this does not acknowledge the fact that developing worthy concepts is still a time consuming process.
7.2.3 Future Works
Using the 3 Future Senses, more unique ideation would add to the exploration of mobility con- cepts, and combining interesting and relevant concepts into one would give birth to another interesting future concept.
Further development of Twin Premier would be necessary, more than just a mere mock-up.
Further development of the EV chassis, and development of User Interaction design would definitely be beneficial for the final design and study of future mobility.
This paper presented Twin Premier as a concept, with little considerations for mechanical com- ponents and manufacturability, such as hinges and battery sizes which are only estimates. If there was a next development stage, real-world considerations should be met, regarding components, safety and technological requirements.

ACKNOWLEDGEMENT
First of all, I would like to thank everyone involved in this project. The advisory committee professors, Yunwoo Jeong, Chajoong Kim, and Huisung Lee. Professor Yunwoo Jeong was involved throughout the project giving advice on the exterior and interior design of the vehicle. He has given me much advice for more than 3 years as my Advisor. I have learned so much from him which will not be forgotten throughout my coming careers. Professor Chajoong Kim and Professor Huisung Lee have helped me complete the paper, advising context flow and important errors that needed to be resolved.
Without them, this paper may not have made sense!
I am deeply grateful for all the team members of the project who have helped me bring about an interesting research outcome which has definitely led to a fun and unique final concept. They have helped me gain different insights and knowledge, broadening my vision while conducting the project.
Without them, the project would have been ‘less vibrant’.
I would like to thank all the CDE faculty members, who always help CDE students and profes- sors. My late graduation must have only been a burden for the faculty members, especially for Ms.
Jinkyung Kim, Ms. Hyojin Kim who have been kind and helpful as always. I am very grateful for them.
Also thank you to CDE colleagues, I am sure all good things are going to be thrown at them. It was a pleasure to learn with you guys, have team meetings together, have small and large conflicts, and also go on trips like Germany and Gwangju. They are all important memories to be kept and shared later.
