About
What is REMOTE SPACE?
Background
At present, automated driving is becoming more and more popular in the automotive field, but with current technology, drivers cannot completely separate themselves from the control of the car. The purpose of this project is to help drivers maintain concentration on the road conditions in an automated driving environment.
Purpose
1.Pay attention to the road conditions at all times
2.Prevent the driver from taking off the steering wheel
2.Prevent the driver from taking off the steering wheel

Benefits of driving automation for commercial use
1. Use data to reduce fuel consumption
HPLS-high precision lateral sensing, with lateral accuracy 54% higher than the industry average.
2. Improve transportation efficiency based on algorithm models
Eradication algorithm to increase vehicle speed and reduce unnecessary paths.
Risks of driving automation
Data Details
Tesla’s "Full Self-Driving" software from around 12,000 vehicles to almost 400,000 in about a year.
The Washington Post analyzed NHTSA's numbers and found that Autopilot was involved in 736 crashes since 2019, including 17 fatalities.

Human Drivers Behavior
Drivers are driving whenever these driver support features are engaged
Drivers must constantly supervise these support features; steer, brake or accelerate
Drivers are driving when these automated driving features are engaged
Drivers must take over if required
Not require drivers to take over driving
Automation Function
be limited to provide warnings and momentary assistance
provide steer, brake or accelerate support
provide steer, brake and accelerate support
Under limited conditions and will not operate unless all required conditions are met
drive the vehicle under all conditions
Currently, the highest level of automated cars allowed on the road is L3.
All state laws hold the human driver responsible for the operation of their vehicles.

Methods to enhance Situation awareness
Method 1Change information visualization form
Method 2Convey information through senses
Conclusion
Most methods lack engaging elements. So it is challenging to maintain SA throughout the entire duration

INSIGHT
Improve automated driving safety
Krome et al.
Making in-car music interactive and align music creation with the progression of the traffic situation. It was proved as a creative activity promoting situational awareness while autonomous driving in difficult traffic.
Muguro et al.
Designed a driving simulation that integrated gaming as NDRT to enhance road detection. These games indicated general risk level of driving context rather than specific risky objects on the road.
Enhance user engagement
Togwell et al.
Explored the use of AR headsets to leverage passenger travel environments.
Lakier et al.
Identified the potential for "cross car" multiplayer games played among occupants in nearby vehicles.
Conclusion
There has been a lack of games that effectively combine pleasurable experience with positive influences to SA.
Furthermore, the influence of different game styles on SA and drivers' experience remains unclear.

Gamification, a promising approach
Gamification is defined as the utilization of game design elements in non-game contexts.
Goals and Tasks
Set up meaningful game backgrounds and clear missions.
Progress and fulfillment
When a certain amount is reached, milestone rewards are given.
Unknown and Curiosity
Motivate users with unknown rewards.
Creativity and Feedback
Creative games with unexpected results.
Ownership and Acquisition
Set the collected objects for the user.
Loss and Escape
If the player fails to act in time, the reward will be lost or the opportunity will be missed.
Social Influence and Relevance
Multiplayer games in which players compete or cooperate together.
Scarcity and Desire
Make the collection have a variety of scarcity properties.
How to take the advantages of gamification to improve situation awareness?
Design Purpose
Pay attention to the road conditions at all times
Convert real-time traffic information into a gamification design that can be played on car play, changing the driver's attention to the road conditions in a fun way.
Prevent the driver from taking off the steering wheel
Even in autonomous driving mode, the driver still needs to keep his hands on the steering wheel so that he/she can quickly take control of the driving when necessary.
Danmaku game
The visual effects of Danmaku games are similar to traffic flow.
Game Type
A.Offensive mode
B.Defensive mode
B.Defensive mode
Steering wheel peripherals
The game requires a joy-con to operate. If the steering wheel is used as a joy-con, the driver needs to keep holding the steering wheel.

Game play testing and selection
Conclusion
Choose defensive mode
1. Offensive mode requires the driver to move the car, which does not conform to real road conditions.
2. Defensive makes the driver more alert and raises the awareness of the need for "self-defense"
Steering wheel peripherals Design
Game Operation
The shield takes the car body as the center of the circle and can rotate freely 360 degrees.
Keep hands on the steering wheel
Conclusion
Choose Encoder wheel
The Encoder wheel can be adapted to the driver's grip position and can be moved up and down with the thumb.

Conclusion
1. Use 3D white models for visual packaging to reduce the cost of information transformation
2. Using the wavelength effect to represent ‘vehicle attack’ can better express the ‘safe distance’

Game Interface & scenes
normal situation：
Block the car, unblock the car
1
Get Encoder wheel input
After successfully blocking, the radar disappears.
2
Blocked successfully
After successfully blocking, the side car turns gray and drives away.
3
Blocked unsuccessfully
After the block fails, the side car turns blue and there are blue light prompts on both sides of the interface.
Blocked successfully
Vehicle turns gray and drives away
Block failure, blue warning reminder
Vehicle lane change：
Warning in advance
4
Take Over Warning
A warning pop-up window pops up to remind the driver to return their attention to the actual road conditions.
5
End Settlement
After the trip, provide data prompt feedback and record the driver’s concentration information.
Blocked successfully

Testing & Reflection
Game Interface & scenes
Conclusion
Many testers failed to block either because they were unable to react centrally or because they were traveling too fast and were unable to react in time. The radar wavelength can be modified under different road conditions to give users enough reaction time.
02
After blocking, the vehicle still in the dangerous range
Conclusion
In a traffic jam, vehicles on both sides will continue to be in dangerous areas. The judgment time should be increased by 10 seconds after blocking. If the vehicle on the side exceeds 10 seconds, it needs to be reset.
03
Determination of side vehicle intruding into emergency danger zone
Conclusion
The side vehicle will issue an emergency prompt whenever it wants to turn, allowing the driver to pay attention to the real environment in advance and stop the game at this time.
