Introduction: Lu Ying Accompanying is a passenger car for families in 2035. The model is between SUV and MPV. It is driven by pure electric, including L4 automatic driving of single vehicle and L5 automatic driving under cluster restriction conditions. The power system is placed on the chassis in exchange for the largest possible interior space. Three rows of seats are arranged in the car, dividing the driving and riding spaces. The seating space is designed in a semi-package manner with reference to the layout of the living room, with the center being the rear table board; the driving space is designed with the driver as the center, and the functional zones of the driving position and the passenger position are clearly divided. The steering wheel of the driving position can be in automatic driving mode. Stow. The first two rows of seats are integrated two-way seats, which can be completely reclined when entering the viewing mode, and are integrated with the rear seats to become a space for 3-4 people to lie down comfortably. There is a touch screen across three rows of seats on the inside of the doors on both sides, regardless of whether the passenger is sitting or lying, they can touch in the comfort zone. When entering the viewing mode, all the screens in the car will enter the sleep state, and the electrochromic film on the screen will also be powered off, turning the texture of the screen glass to frosted and the color to black, so as to reduce the reflection during viewing and integrate with the interior decoration.

Project Source The project originated from the Desai Siwei-Hunan University Automobile HMI Design Competition. The conceptual design accompanied by Lu Ying was one of the winning works and was sponsored by Desai Siwei's physical model. On the basis of the solid interior model, I carried out further exterior design and interactive prototype development, and built an interactive experience warehouse for watching movies in the driver's seat. Existing solutions in the industry The existing passenger cars and concept cars with movie-watching functions are basically based on the central control screen as the movie-watching screen, which is represented by the 48-inch central control (the largest in the world) of Baiteng. The (model) released by Xiaopeng Motors at the Shanghai Auto Show includes a scene where the front seat is down and the curtain is hung in the car to watch the movie. Both of the above models have their shortcomings.

The design center of the central control in the ergonomics of the car is the driver, which conforms to the driver's observation in the driving position with a head-up or overhead attitude, but its sight distance and elevation angle cannot meet the basic requirements of movie projection ([1] GB/T 3557-1994 Technical Requirements for Audiovisual Environment of Cinema). Xiaopeng's plan turns the four-seat driver's seat into a two-person viewing position, which limits its use of scenes. Its users are the current Z-generation youth, which cannot meet the needs of family users and the whole family. However, the current generation Z will be over 35 years old in 2035, and most of them have formed their own families, with the highest willingness and strength to buy cars among all ages.

Watching mode
The road shadow accompanying the electrochromic glass is used for the front windshield and roof glass of the car, turning the largest and most frequently watched area in the car into a carrier for viewing and entertainment, and can get excellent viewing in a lying position. Movie experience. When the electrochromic glass becomes frosted and opaque, the hidden ultra-short focus projection on the roof is activated, and the viewing area can be adjusted with the calculation of the viewpoint of the passenger's lying position in the car. The front and rear tables are equipped with constant temperature diet dishes to meet the low frequency of long-term viewing. The viewing mode is generally started when parking. In some special road environments (2035 car theaters), the vehicles enter the area with a unified configuration of automatic driving, which can be used to match the driving state of the vehicle and seat adjustment during driving.

When watching the movie, you can cooperate with the car air conditioner for odor delivery and temperature and humidity adjustment. In addition, the reflective ultra-short focus projection can be turned outward from the roof. For users who want to get more traditional cinema seat viewing experience, the projection screen in this mode is located directly in front of the car, and the user can sit in the car. Watching the movie through the front windshield, you can also pull out the external seat behind the bumper at the grille of the front of the car, and use the external speaker to watch the movie in the open air. When multiple cars are in the same queue, the projection of the roof can use the mosaic standard for multi-projection collage, forming a huge picture on the surface of the wall or curtain, and becoming a multi-car car theater.

Applicable population
Traditional cinemas are not friendly to family viewing. ([2] 2020 China Film Market Data Survey Cat's Eye Movies) On the one hand, traditional cinemas cannot meet the needs of family viewing for member interaction, and lack privacy space, and their open conditions are easily affected by factors such as epidemics; private cinemas of a business nature provide a space similar to family viewing, but cannot provide the same comfortable, familiar and hygienic home environment; home cinemas are limited by the space and acoustic layout of houses, at the same time, there is the dispersion of hardware, the cost of layout is high, and the most common entry-level home theater is difficult to achieve the optical and acoustic effects of the theater.

As a limited enclosed space, the car has a pre-arranged acoustic environment. The control efficiency of environmental variables such as temperature, humidity, and smell in the car is higher than that in the room. The high-density image and sound media equipment also make the sound and light environment in the car The control is better than the relatively sparse indoor media. It can be said that the car is one of the most closely combined consumer-grade products made by human beings in the atomic world and the bit world.
Design
Interior design and screen layout occupy most of the design time. The process of interior sketch and model deduction has been carried out for 3 months. It mainly focuses on the layout of cinema and family. The exterior design focuses on the display of movie elements and the design of door opening. The morphological characteristics of the wheel come from the transmission wheel of the film projector. The whole wheel uses a gentle shape and a large curvature door panel to highlight the characteristics of the home mobile cinema. The design of the interactive interface refers to the design style of Google material design, and the UI presents a sense of depth and stereoscopic impression visually. Since the entire central control is replaced by a screen, how to fit the texture of the interior decoration from the screen content is also a design style problem.

Passengers in the main driving position, the co-pilot position and the living room-like position on the rear side of the car can control the car environment and access specific functional areas on the touch screen that extends twice. Compared with the large-size central control screen, the UX of the long screen on both sides and the small screen on the table almost only keep all the contents of the first-level menu icon and the necessary data display. Passengers are required to initiate touch events to display the corresponding secondary menu prototype. The prototype accompanying the hardware frame road shadow uses two 23.8-inch touch screens as the central control screen and a smart phone as the steering wheel part, the wooden frame undertakes a 1.2m × 2.4m high-transparent acrylic plate as a simulation of the front windshield and roof glass. The acrylic plate is covered with an electrochromic film to adjust the transparency and serve as a curtain for viewing.

The projection behind the wooden frame is used as the light source of the roof screen, the modified electric sofa is used as the driving seat of the car, and the Xbox kinnect camera at the front of the experience warehouse is the detection component of gesture interaction. The overall interactive prototype of the software framework and the interconnection between devices are mainly implemented by using the ja-vasc-ript P5.js library. Other libraries include P5.dom.js (video component control),P5.sound.js (audio component control), socket.io (multi-computer communication),kinnectron (somatosensory gesture detection),easing.js(UI slow motion animation),P5.serialport(P5.js and Arduino communication), the overall development workflow is: UX/UI design draft-local VScode editor drawing interface-openprocessing online editor multi-page.
