This was originally posted in my personal blog (Dec 17, 2009), and I thought it would be better placed here in this section. I couldn't just move it without losing the comments or the original URL, so I'm just going to copy it here. Enjoy.
Anyway, the format of the book is unique. As the description says:
The editors use a distinctive format for the book, consisting of a set of chapters composed of three parts: a story or vignette that describes work conducted within a synthetic world based loosely on the question, ‘what will work be like in the year 2025?’, founded on the expert authors’ expectations of plausible future technologies; a scholarly review of the technologies described by the stories and the current theories related to those technologies; and, a prescription for future research required to bridge the current state-of-the-art with the notional worlds described in the stories.
What I wanted to do here was share part of my chapter with you, at least just the fiction part. The rest of the chapter gets into the technical analysis, scholarly review, etc. This is the unedited version (the final is much cleaner), so please ignore any glaring writing errors. I hope you enjoy the short story…I might continue it at a later date depending on reader response (I had a limited amount of space to work with in the chapter).
The call had arrived at a little past two-thirty in the morning and Kendra had drawn the short straw to venture out in the freezing rain that had been cascading from an inky black sky for the last several hours. She waited at the stoplight, listening to the soft hum of her electric car and the turn signal’s metronome clicking away little segments of time. She was tempted to let her mind wander while staring at the glistening raindrops snaking their way down her windows and brightly lit by the stoplight. Kendra had always felt something mysterious about inclement weather in the middle of the night, especially when there were only few people on the roads heading to some unknown destination. The only thing that could make the atmosphere a little more surreal would be snow materializing out of eternity and blanketing the city in silence, with only the reflections of street lights free to echo through the night.
The light finally changed to green and Kendra turned her mind back to the task at hand and drove the rest of the way to the crime scene, preparing herself for her work.
Kendra arrived at the scene and shouldered her way through the overly eager press reporters that had already gathered like hungry vultures desperate for a meal. She ignored their barrage of questions and ducked under the police cordon, showing her badge to the officers attempting to control the growing crowd. This was the fourth murder in as many days and the public was beginning to demand answers. She made her way across the driveway and up the brick stairs leading to the front door of the house, dodging the growing pools of rainwater that would soak her feet if she wasn’t careful.
She entered the house and waited while most of the other officers cleared out to give her some room. The medical examiner had already been on the scene and the bodies were taken away. Kendra could sync up her databases with the examiner’s later, it was time for her to do her own work now. She set down her bag and reached up to her glasses, tapping a barely noticeable touch sensitive key at the corner of the frames. A softly glowing heads up display pulsed into existence in front of her, immediately sensing her location in the real world and on the meta-net.
“Initialize.” she commanded. “Voice authentication: Alpha-Zulu-Romeo-Bravo-Zero-Niner-Seven.”
A nondescript male voice spoke in her ear. “Authenticated, Lieutenant Kendra Jackson, Enhanced Sensory Perception, ESPer Team 5”
“Begin scanning, crime scene, domestic, murder.” She began to look at every area of the room, making a few mental notes of things she would pay special attention to when she returned for her detail and evidence collection sweep. The voice spoke in her ear again. “Location confirmed. Date and time confirmed. Scanning in process. Comparing visual point cloud to public architectural records and builder plans. Synchronizing. Process complete.”
“Display wireframe” she said.
“Wireframe active. No anomalies detected.”
Faint blue lines appeared, following the course of the walls, the floor, the ceiling, the doorframes, and every other part of the house that she could see. It was like seeing a 3D blueprint of the house overlaid on the real thing. This served multiple purposes, but for now she needed it to act as a reference for the scale, positioning, and orientation of everything in the house, particularly any evidence she would come across. She remembered hearing stories of a SWAT team that had used augmented glasses and the wireframe to navigate through a pitch black office building where terrorists had cut the power and had set off multiple smoke bombs. They never knew what hit them. After that particular incident, Fire departments all over the country began requesting the same gear. Not being able to see where you were going in a smoke filled building was no longer a problem. You simply needed to follow the blue lines or the floating translucent red arrows that pointed towards the nearest exit. Life was so much easier with augmented reality and the glasses.
“Activate WATSON” she requested, almost without thinking. She had grown accustomed to working with the artificial life intelligent agent. Originally he was not much more than a tool that helped gather information and run intelligent semantic database searches, all wrapped up in a life sized human representation. Kendra had spent a lot of time and a fair amount of her own money to customize him to her liking and upgrade his program with a more realistic personality and some law enforcement grade functionality that was not available to the public.
“WATSON is now online.” The voice stated. She wondered if she should change her settings and give it a personality or if she preferred it to be completely devoid of any emotion. Having WATSON around was more than enough she guessed.
Kendra turned her head slightly and regarded WATSON, who was now standing in the middle of the room wearing his usual Victorian garb and peering at his surroundings while muttering to himself. He was faintly translucent, which was required by law for any virtual person, human controlled avatar or AI-driven persona. There were some public safety reasons for this and people generally preferred to keep it that way, mostly for the same reasons that humanoid synthetic androids were restricted from being too lifelike.
“WATSON, access the domestic security system and copy the logs from the last 72 hours” she said to her virtual companion while she began to start walking around each of the rooms on the first floor, observing everything.
WATSON nodded and pulled a worn leather-bound journal from thin air and started to make notes in it. He stopped muttering to himself and looked quite intent on his recording task. When he was finished, he walked out of the room, waddling slightly (he was a tad overweight, and it affected his walk cycle) and caught up with her.
When Kendra completed her initial walkthrough, she returned to where she began and started collecting evidence. Every bullet and casing were recovered, lasers used to determine angle of the bullet holes in the wall, fingerprints lifted, bloodstains sampled, and so on. By the time she was done, a highly detailed 3D mirror of the entire house had been created on the servers back at the station. Every photograph she took and corresponding video clips of everything she saw were also stored, but each was tagged with appropriate time and location data. She had taken the time to attach some notes and observations to a few key items and places of interest in the house. Anyone looking at the 3D version of the crime scene would have ready access to all of the data and her notes.
As Kendra was packing up her gear and preparing to leave, she had a sudden hunch. “WATSON, display all augmented reality content and channels associated with this residence please.”
“Ah, yes yes, good idea Ma’am. Complying.” WATSON looked like he was staring off into the distance at something vaguely interesting, while a wide variety of virtual objects began popping into existence. Normally, this would only be visible to the residents and friends that have access to their channels. Some abstract art materialized on one wall, shifting patterns and undulating waves rippling across the largest piece, their smooth motion was mesmerizing. A few virtual pets popped into existence next and started scampering around playing at some learning game intended for young children. A wonderfully detailed plan for a new house slowly appeared on the dining room table complemented by a soft woman’s voice reciting a sales pitch and mentioning a number of optional additions that could be purchased.
WATSON frowned and coughed politely. “I’m sorry, but there seems to be some additional content here that is restricted. It is not listed on the normal public and private channels. It may be an illegal hack. Shall I attempt to access?”
Kendra considered for a moment. Normally, law enforcement personnel have access to all AR content, public and private, within the domain of a crime scene, but there were some levels of protection and privilege that required a court order or security clearance to access. In cases like these, discretion was usually prudent and it was safe to obtain a warrant first. Then again, there was a strong possibility it was an illegal hack and this was a murder scene, not a regular crime scene. Kendra’s curiosity and intuition got the better of her.
“Force access WATSON, on my authorization. All means necessary.”
“Yes Ma’am. I shall do my best”. WATSON’s eyebrows furrowed and little beads of sweat began to form on his virtual brow. A few long minutes passed and Kendra started wondering if WATSON had locked up…he hadn’t moved in a bit and even flickered a few times, which was extremely unusual. She was about to give up and restart his program when he lurched with a gasp and a pained look on his face.
“Ahem, that was extraordinarily difficult, but I seem to have succeeded. A spot of tea would be really nice methinks.”
“Thank you WATSON, what is the location of the hidden content?”
“In the living room I believe. Shall we investigate?” queried WATSON.
“Of course; this should be interesting.” Kendra grinned and headed towards the living room. She stopped short at the doorway and stared at the center of the room in disbelief. A massive floating black skull hovered there, blood-red fire silently blazing in its hollow eye sockets, and a nasty black ichor dripping out of its mouth on to the carpet. The pools of liquid that formed stretched out and oozed across the rug to form intricate letters spelling something out in a bizarre language she did not recognize.
“Oh, my, this cannot be good.” WATSON said, stating the obvious.
“No kidding. Begin scanning the usual databases for gang signs, military unit insignia, secret societies, tattoos, and ancient symbology. I think we may have stumbled onto something that we weren’t meant to discover” said Kendra. “Let’s head back to the office and start putting the pieces together.”
The next several days were a blur for Kendra. Most of her time was spent processing evidence, populating the database with all of the information and media, and focusing every remaining waking moment trying to research the origin and meaning of the skull. It didn’t take too long to establish a timeline of the crime and how the murders occurred, but her research efforts resulted in a lot of dead-ends and few leads.
It was Thursday afternoon and Kendra headed over to the simulations room to tweaking her presentation before the staff briefing the next day. The higher-ups were demanding some progress and wanted to look at her work so far. She went to Room Three, which she had reserved earlier, and looked around. Room Three was entirely empty and slightly larger than a racquetball court. The walls and floor were painted a light grey color with thin black registration marks at every corner. She thought it was pretty depressing and wanted to get started.
She touched the corner of her glasses and went through the usual initialization and authentication process. “Load SIM four-zero-three, set location to living room.” Kendra paused and waited while her command was processed. After a few second a photorealistic 3D mirror of the crime scene faded into existence. Every detail was reproduced exactly and to scale, all based on the visual data she had recorded during her initial walkthrough and subsequent evidence collection at the scene.
Kendra continued giving the main computer additional commands, and after half an hour or so, the victim’s bodies were also visible. Faint red beams crossed the room, originating at each of the areas where the bullets were recovered, giving her a good idea where the killer or killers had stood and fired from. All of the fingerprints that were taken were also referenced, faintly glowing various shades of green. She touched a pair that was on the coffee table and a small window materialized above the prints with a zoomed in version and information about who the prints belonged to. In this case, the prints were marked as unknown and not in any of the usual fingerprint databases.
She moved on, making notations and observations to each area of evidence. Everything was checked and rechecked. Kendra reviewed all of the collected data and media, making sure everything was properly linked to the relevant objects. If there were any questions at the meeting, she literally wanted everything at her fingertips. All it would take was a brief touch on anything (or anyone) and all of the reports, photographs, video clips, and lab data would be instantly viewable to anyone in the room.
Once she was satisfied with everything, Kendra started tweaking the reconstruction of the crime based on the evidence they had so far. She started by tracking backwards from what the Police discovered when they responded to the crime, continually adjusting the position of each of the victims as she worked through the timeline. When she finished, she directed the system to fill in the blanks based on the forensic data already in the database.
After the processing was complete, she would be able to view a realistic recreation of the crime from any angle and perspective. The combination of the 3D objects, advanced physics modeling, and actual forensics data made these simulations incredibly lifelike. She had heard stories of the occasional jury member being shocked after witnessing these simulations in court, particularly if the crime was unusually brutal and violent. It felt like being an unseen ghost right in the middle of the crime as it occurred, and was much more compelling than the old way of relying on photographs, charts, and awkward animations on a projector screen. This put you THERE and left little doubt as to what happened. Kendra wondered how long it would be before the engineers would figure out how to implement smell and tactile feedback.
She ran through the simulation a few times and checked all of the datapoints once again to make sure she hadn’t missed anything. It was good enough she supposed. Maybe she should take another hour or two and check in with some of her contacts that were helping her with the skull research and then call it a night. Her boss didn’t take kindly to oversleeping or flubbing a presentation with the brass due to lack of sleep. Tomorrow should be interesting. She hoped the press didn’t show up, that always made her nervous.
“Save all files, backup, and copy to private storage. End simulation.” Kendra looked around at the empty room once more and left for her office.
