Perfect auto-driving car technology is not enough
Our auto-driving car technology has indeed improved, but if there is no trust of the passengers, auto-piloting is difficult. When a self-driving car takes us on the road, having a driver sitting behind the steering wheel will make passengers feel at ease. Once there is no one in the driver's seat, will you still get in the car?
The future of self-driving vehicles is embarrassing. Some experts predict that by freeing humans from the driver's seat, we can save hundreds of lives and make safe travel a reality. However, the difference between theory and practice can be attributed to: people's fear and distrust of robot cars. In fact, a recent AAA survey found that 75% of Americans are afraid of riding a self-driving car.
The good news is that this is a problem that can be solved. Intel believes that by creating an interactive experience between cars and passengers, consumers' fears can be overcome. This interactive experience can provide rich information and make people feel comfortable - in short, trustworthy. Our user experience team's "trusted interactive survey" of self-driving car passengers demonstrates this potential.
We have conducted limited and qualitative research on consumers who have never been contacted or have seen a self-driving car with their own eyes. They were invited to take the autopilot test car and feedback their ride experience. We set out five scenarios for trust and interaction and evaluated them: calling cars, starting driving, changing journeys, handling errors and emergencies, parking cars at the roadside and getting off. We asked questions before and after consumers took a self-driving car and recorded their reactions during the experience.
Although the scope of the investigation was limited, the results were consistent. Each participant had a huge leap in the level of trust in self-driving cars at the end of this journey. Even those who are worried about self-driving cars admit that self-driving vehicles are a safer mode of transportation and they are optimistic about the development of this market.
Although this investigation has yielded a lot, it is only the beginning. Our survey found seven "critical points" of trust worth exploring (see below). Intel will continue to study the user experience and share these findings with customers. When the industry’s first driverless car begins to drive on the highway, our findings will help the industry deliver trustworthy driverless cars. The driverless future depends on it.
HMI-Trust Point of Trust:
Human judgment vs. machine judgment
One issue that the participants are very concerned about is how to deal with subtle situations in the driverless car if there is no one's judgment—for example, a person suddenly crossing the road or other driver accelerates faster than the unmanned vehicle. However, they also believe that because of the elimination of misjudgment, driverless cars will be safer and will be stronger in decision-making than humans who rely on second-hand guesswork.
Lack of assistance to assist vs personalized space
There are plenty of free time when riding a self-driving car - this idea has inspired many people to start thinking about how to use this time, while others are concerned about not being able to interact with human drivers. For parents, the use of a self-driving car to pick up a minor who is alone has a huge advantage - there are no strangers/drivers in the car. However, participants also fear that without a driver there will be a lack of accountability. It also takes into account the aspirations of physically handicapped people - especially if there is no driver's help, how physically handicapped passengers can get in and out of the car.
Conscious vs excessive information
Most participants believe that a learning curve is needed to adapt to the autopilot system. But once the trust in the system begins to increase, they will feel that some warnings and communications are particularly annoying and disturbing. Although security tips and contextual information are very convenient, they do not want to be distracted by too much information.
Give up control of the vehicle vs control the vehicle from a new level
For some people, sitting in the back seat of an uncontrollable vehicle is an uneasy feeling. Just seeing the unnatural rotation of the empty driver's seat and steering wheel can also cause some anxiety. Participants explored the removal of these traditional vehicle designs to ease tension. At the same time, they also attach great importance to the new control experience: the ability to use a mobile device to call a car and unlock/open the door, reduce the pressure to drive, and feel safe and comfortable with more “eyes†to observe the road conditions.
Learn how it works vs prove its effectiveness
Understand how the technology works and all its capabilities - this is the most important for the participants. At the same time, seeing and experiencing how cars perceive and react to what is happening around them will give participants confidence in self-driving cars. Therefore, the transparency of the HMI system is very important.
Tell me vs listen to me
When the "voice of the car" makes participants relax, many people want to know if they can use their voice to communicate with the system (this is not part of the test). Being able to talk to the driver and exchange information - this can be a big advantage, especially when it is necessary to bypass, change destinations, or the weather is constantly changing.
Obey the rules of the machine vs human interpretation of the rules
Although security is the first element of trust for participants, their understanding of security is subtle. Some participants admitted that their own behavior when driving a vehicle was not always safe or that they did not drive in full accordance with the traffic manual. They talked about speeding up on empty roads, eating while driving and sometimes not parking where they had to stop. Participants acknowledge that the struggle between giving up on these behaviors and accepting new system-based behaviors is a challenge they must adapt to.

â‘¢ Countdown Timer ON & OFF
â‘£ 4 MODES:
Set > Detected: When the light intensity detection value is less than the set value, switch ON or OFF.
Detected > Set: When the light intensity detection value is greater than the set value, switch ON or OFF
ON : Always ON
OFF : Always OFF
NOTED:
1. The light intensity displayed by this machine is not the standard light intensity value (Lux), only the relative light intensity value.
2. The light intensity value is affected by the placement position and direction. Please determine the position first and then set it according to the actual light intensity detected. If you change the position or change the orientation, you need to reset the light intensity setting value suitable for the new position.
3. This product has built-in rechargeable battery. If it is not connected to AC for a long time, you need to connect the power supply to charge until the LCD can display normally.
MANUAL OPERATION
1. Press [UP" or [DOWN" to set the LUX value.
2. Press the [SET" key to start setting, and the P1 settable items will be flashed.
3. Press [UP" or [DOWN" to adjust the value.
4. Press [SET" key again to exit setting or enter next setting for countdown timer.
5. Repeat the [SET" key to start setting, and the P2 & P3 settable items will be flashed.
6. Press the [FUN" key to switch the working state in the following:
Set > Detected -> Detected > Set -> ON -> OFF
Set > Detected: Automatically switches when the detected ambient light intensity is darker than the set value
Detected >Set: Automatically switch when the detected ambient light intensity is brighter than the set value
When the brightness meets the setting conditions, the countdown starts as below:
Note:when the countdown is ON, the detected value is not displayed.
When the brightness does not meet the setting conditions, the countdown stops and waits:
After the countdown ON is reduced to 0, the countdown OFF starts immediately and the power is OFF.
After the countdown OFF is reduced to 0:
A. If the light intensity meets the set conditions, a new round of countdown will be started;
B. If the light intensity does not meet the set conditions, keep the power off and wait for the light to meet the conditions before turning on automatically.
NOTE:
1. If the power is cut off while the countdown is running, the countdown will be terminated immediately and the relay output will be off. After the power is turned on again, a new round of brightness detection will start.
2. Modifying the brightness value in the countdown operation will not affect the current countdown operation. After the off time of the current countdown, the new brightness setting value will take effect.
3. In the countdown on operation, change the setting value of the countdown on, this countdown will still be timed according to the original setting value; the new setting value will take effect when the next countdown on starts.
4. In the countdown off operation, change the setting value of countdown off, this countdown will still be timed according to the original setting value; the new setting value will take effect when the next countdown off is started.
NOTE: the brightness setting value, countdown ON or countdown OFF, any one of which is equal to 0, cannot be switched ON or OFF automatically.
