“You’re right. She’s awesome,” Sam said.
Fargas looked over. “Reckon she gives private lessons?”
“She’s not real, dude. Just a bunch of pixels,” Sam said.
“Works for me,” Fargas said.
Sam laughed. “If she was real, I’d love to meet her.”
“Get in line,” Fargas said.
Ursula continued, “Your neuro-connection will allow you to put away your keyboard and mouse, and eventually even your computer screen, and interact with your computer simply by using your brain. If you haven’t already plugged in and attached your headset, do that now. I’ll wait,” she said with a beguiling smile, then added, “If you need help with any of the equipment, press F1 now. When you are ready, press Enter.”
Sam did exactly that.
Ursula’s face shrunk to the top right of the screen, and a graphic appeared, a three-dimensional image of the headset, rotating slowly.
“You are now wearing the latest technology Neurotech 1.2 headset. Embedded sensors detect signals produced by your brain that you know as brain waves.”
Sam ran a hand over his head, feeling the slightly raised bumps on the headset.
“There are four main types of brain waves: alpha, beta, delta, and theta,” she said. “The ones we are interested in are the higher-frequency but low-amplitude waves, known as beta waves.”
The graphic changed to show a colorful chart, a little like a topographical map.
Ursula said, “Beta waves are unique to each individual; however, certain patterns are common to all people. By detecting those common patterns and training our patented Neuro-Sensor software to recognize your own individual patterns, it is a simple and easy process to control your computer, just with the power of your own mind. If you have ever used speech-recognition software, this is a quite similar process.”
Her face disappeared altogether, and a screen appeared that looked like a scene out of a video game. The graphic showed a dog standing on a long winding pathway through a park. Each side of the path was lined with a row of small shrubs.
Ursula spoke. “Steer left and right to stay on the path. Concentrate on making the dog move. Focus on the dog and mentally turn it the way you want. When the dog turns to the left, press the ‘L’ key on your keyboard. When it turns to the right, press ‘R.’ This will help train the Neuro-Sensor software to recognize your brain-wave patterns for left and right.”
The dog started walking. The path began to curve to the left.
Sam focused on the dog and willed it to turn. It didn’t. He tried to move the dog with his eyes, as if he could pick up the dog with his gaze.
The dog walked into the shrubs and stopped.
“Let’s try that again.” Ursula came back on-screen with an encouraging smile.
“Imagine you are the dog,” Fargas said, “and it is you that is turning to the left or right.”
“Woof,” Sam said.
The dog reappeared at the start of the path. Sam tried to imagine he was the dog, but still the dog walked into the shrubbery and stopped.
“Don’t give up; you’re doing well,” Ursula lied cheerfully. “Press Enter to try again.”
Ten minutes later, he was starting to get sick of Ursula and her happy, happy attitude. A couple of times the dog had flickered a bit, as if it was trying to turn one way or the other, but that was the best he had achieved.
“Try again,” she kept saying.
“I hate dogs,” Sam growled.
“I know what your problem is,” Fargas said.
“What?”
“No detectable brain waves.”
“I’m starting to wonder,” Sam said.
“Try turning your whole body,” Fargas said. “That’s what worked for me at the start.”
Sam stood up and this time simply turned his whole body to the left.
To his utter amazement, and no small relief, the dog turned hard left and crashed into the shrubs on the other side of the path.
Sam stabbed at the “L” key.
Ursula’s face appeared for a moment on the screen with a huge smile. “Great work!” she said, and winked.
“I think she fancies you,” Fargas said.
“I have that effect on women,” Sam said.
Fargas laughed and filled his mouth with caramel corn.
Sam tried again, turning to the left or the right, and found that he was able to keep the dog on the winding path for quite long periods. More importantly, though, after he had pressed the “L” and “R” keys a few times, he realized that he no longer had to turn his body physically to make the dog turn. If he just thought about turning, the dog moved in that direction.
After a few minutes of doing this, he was still half amazed that it was actually working.
Ursula reappeared with a few thoughts of her own. “Looks like you’ve got the hang of left and right,” she said. “Let’s try up and down.”
The graphic this time was a small airplane flying through a cloudy sky.
Sam pressed Enter and the plane flew straight into the nearest cloud and exploded.
“Nice,” Fargas said.
Sam ignored him and started over.
This time it took him just a few tries to get the hang of it, maneuvering the biplane up and down to keep it in the blue-sky part of the screen between the clouds.
As he flew on, the clouds grew thicker and larger until there was just a narrow path between them.
It took him a couple more tries before he really mastered it, dodging up and down to keep in the blue. As he flew farther and farther, he noticed the plane was speeding up. The clouds came faster and faster until they were little more than a blur across the screen. Still he dodged them, flicking the little plane around the sky until at last it emerged into a bright, cloudless sky, which gradually dissolved into Ursula’s cheerful face.
“Well done!” Ursula said. “Now let’s put it all together.”
The third game had a fish swimming through hoops in the ocean. He moved left and right and up and down to aim the fish through the hoops. Again the game got harder as it progressed, the hoops getting smaller, the fish getting quicker. He completed the test on the first try.
“We’d better get going,” he said, looking at his watch. “Or we’ll miss the convention.”
“Just a few more minutes,” Fargas said. “You gotta try this Neuro-Doom—it’s awesome!”
Sam looked at his friend’s screen. Fargas was operating the computer with his eyes shut, moving around inside a virtual-reality game, armed with a shotgun.
“Don’t get addicted.” Sam laughed.
“No chance,” Fargas said. “Die, monster, die!”
“Come on,” Sam insisted.
Fargas reluctantly removed his headset and closed his laptop.
Sam glanced back into the room before closing the door behind them.
The webcam sitting on top of his old laptop on the desk by the window was aimed at the door, as if following them out of the room. The last time he had looked at it, it had been pointing straight ahead.
Hadn’t it?
5 | FREAKS AND GEEKS
The graffiti-covered door of the old warehouse opened and shut again quickly as another Darth Vader entered. Across the road, Sam checked his watch.
“Shame Ursula couldn’t come,” Fargas said.
