He could still understand controlling a phone with a QR code; after all, Trojan viruses could be hidden in QR codes.
But being able to control a phone just by shining a laser pointer on it was too mysterious.
Elliot smiled slightly and explained, "Our phones all have voice assistants, such as Aura's 'Aura Assistant' and Pear's 'Iris'.
And this laser pointer in my hand has undergone special modification and can remotely send commands to the phone's voice assistant, open phone applications, and even control smart home devices."
Elliot paused for a moment and asked, "Does everyone believe it?"
"We believe!"
Unexpectedly, the audience answered in unison that they believed.
"Hey, how can you be like this? You believe whatever I say? You can't do that," Elliot said, pretending to be angry. "This doesn't have any show effect. I'll give you another chance. Now, do you believe that I can remotely open your phones with just a laser pointer?"
"We don't believe it!"
This time, the audience had learned to be 'smart'.
"Haha!" Laughter erupted simultaneously.
"That's more like it." Elliot nodded with satisfaction and continued, "You don't believe it? Alright, who doesn't believe it and is willing to try?"
"Whoosh!" In the audience, nearly a third of the spectators raised their hands, wanting to experience it firsthand.
Even Gary Quinn and Quinn Weaver raised their hands.
"Alright, since everyone is so enthusiastic, let's invite our staff to bring the props onto the stage."
As he finished speaking, a staff member pushed a table onto the stage.
On the table were a laser pointer, a laser driver, a loudspeaker, and a telephoto lens.
Elliot introduced these props to the audience while gesturing for the staff to assemble them.
The staff member connected the laser pointer to the laser driver, then connected the laser driver to the loudspeaker, and finally connected the loudspeaker to a laptop.
A data cable connected all the devices together.
After the assembly was complete, the staff member turned on the laser pointer switch, and a beam of green laser shot out from the laser pointer.
"Let's invite one audience friend. You don't need to come on stage; just sit in your seat and raise your phone... How about the gentleman in the yellow shirt in the back?" Elliot said.
In the back row of the audience, a tall man wearing a yellow shirt stood up.
"Please raise your phone, yes, just like that," Elliot said.
The man raised his phone according to Elliot's instructions.
It was a Pear phone.
"Let's do a simple test first to see if we can wake up 'Iris'." Elliot said, then gestured for the staff member on stage to call out:
"Hey, Iris!"
The man's phone had no reaction.
He was about forty meters away from the stage, and the staff member's voice couldn't reach his phone at all.
"Hey, Iris!"
"Iris!"
"Iris!"
The staff member shouted a few more times consecutively, but there was still no reaction.
"Alright, shouting directly like this gets no reaction. Now, let's try using the laser pointer to see if we can wake up 'Iris'." Elliot said.
The staff member turned on the laser pointer, and a beam of green laser traveled forty meters and accurately shone onto the yellow-shirted man's phone screen.
"Camera, please give the phone a close-up shot," Elliot said.
A camera above the audience moved to the top of the yellow-shirted man's head, aimed the lens at his phone, and projected the image onto the big screen.
All the audience members could clearly see a green light spot appearing on the man's phone screen, at the location of the microphone.
"Did everyone see that green light spot?" Elliot asked. "Now, please, staff member, shout: 'Hey, Iris'."
The staff member heard this and shouted: "Hey, Iris!"
A magical scene appeared.
Forty meters away, the Pear phone in the yellow-shirted man's hand suddenly lit up, and then the voice of "Iris" came from the phone:
"I'm here!"
"Wow!" The yellow-shirted man's pupils dilated, and he looked at his phone in disbelief.
This was too amazing.
It wasn't over yet.
"Open Photos." The staff member continued.
"Opening Photos for you," 'Iris' replied.
Then, the phone's photo album automatically opened.
"Wow!"
The audience at the scene let out exclamations of surprise.
It really worked.
What kind of black technology was this?
"Clap clap clap!"
Immediately following, warm applause erupted at the scene.
"Let me try!" Sam Ning shouted loudly. He took his Aura phone, walked off the stage, and went into the audience.
Sam Ning held his phone up high.
Everyone's eyes were focused on his phone.
"Aura Assistant!" The staff member on stage shouted into the Mike.
The screen of the phone in Sam Ning's hand suddenly lit up, and then the voice of "Aura Assistant" came from the phone: "I'm here."
"Unlock the phone." The staff member continued.
Just then, the phone in Sam Ning's hand actually unlocked automatically.
"Open social media." The staff member said again.
The social media app opened automatically...
"Alright, alright, that's enough." Sam Ning quickly closed the app. He was afraid that if this continued, the personal information in the app would be exposed.
Wahahaha~~
A laser pointer could actually wake up a phone's voice assistant.
Unbelievable.
"Little Boy, what's the principle behind this?" Sam Ning asked curiously.
The audience below the stage also really wanted to know the answer.
"The principle is actually very simple," Elliot explained, "We first convert sound into an optical signal, input it into the laser pointer, and then, through the laser pointer, shine the optical signal onto the phone's screen, or more accurately, onto the phone's microphone."
"Perhaps everyone doesn't know that microphones can not only receive sound waves but also react to light sources, such as lasers, just like they react to sound waves. This characteristic can be used to 'inject' sound into the microphone by modulating the intensity of the laser."
Elliot explained the principle very clearly, but the audience and guests at the scene still felt it was very magical.
Next, the audience at the scene successively took out their phones and asked Elliot to test them.
There were all kinds of phones, Nexus, Nova, and V-Tech phones, all of which could wake up the phone's voice assistant with a laser pointer.
This was impressive.
[Waka, I don't understand but feel it's amazing!]
[This isn't technology, this is magic!]
[It's too amazing!]
['Little Boy' Boss, how did you come up with this method?!]
[It's a bit scary, who would dare to use their phone's voice assistant in the future?]
[I'm turning off my phone's voice assistant right now!]
...
The bullet screen comments in the live stream room surged like a tide.
