I’ve been wondering how much our lives actually align with our plan for our lives. This question is relevant for both big things and little things.
The big things include stuff like “I am going to be married by the time I’m thirty”, or “I am going to get that Ph.D. I’ve been talking about!” Little things might include stuff like “I’m really going to clean out my closet by the end of this year.”
I suspect that when our life deviates from what we planned for it, selective amnesia can set in. We don’t like to think about the things we didn’t end up doing. After all, those things did not actually happen.
Would we be happier, in the long run, if we knew that there was going to be some kind of reckoning? What if we knew, when we made our plans, that we were going to be confronted with any difference between what we said and what we did?
Would that just cause anxiety, because every decision would take on greater weight? Or would it make us happier, because we’d be more likely to actually achieve our goals?
I have no idea what the answer is. But I’ve been wondering about it.
Today I toured a house that is under construction, but nearly finished. Workers are now busily putting the final touches on the cabinets and other fixtures.
I couldn’t help but wonder what the house would have been like if it were designed from the ground up for mixed reality. For example, the great room had twelve foot high lofted ceilings.
That would not have been necessary if people in the house were always wearing those future contact lenses. Furthermore, in that alternate future, you could choose a custom height for the ceiling for any day of the week.
In fact, different people in the room could, at the same time, experience ceilings of different heights. One person might be claustrophobic, and prefer the luxurious feeling of high ceilings, whereas another might kenophobic, and prefer a low ceiling.
Similarly, different people could choose the lighting fixtures and style of lighting of their choice. One person might like natural light through large bay windows, while another prefers the warmth of a room lit by a thousand candles.
In the future, I suspect that architecture and interior design will change quite a bit. This will be somewhat akin to the way that magazines and journalism have changed in an on-line age.
Those things haven’t gone away. They’ve just morphed as they have adapted to a new medium.
Sometimes it seems that a day can take forever. The sun just hangs up there in the sky, and doesn’t seem to move.
But there are other ways to look at it. Suppose we had a train on tracks that encircled the Earth’s equator?
As the Sun makes its way across the sky, this train would keep up. Where the train is, it would always be high noon. How fast does the train go?
Well, the Earth is about 25,000 miles in circumference, and there are 24 hours in a day. So the train would be going a little over 1000 miles per hour.
If you were standing right next to those tracks, you would say the train was going fast. Very, very fast.
So the next time you think the Sun doesn’t seem to be moving in the sky, you might think of that train. If you think about it long enough, the day might go by quickly indeed.
You may end up wondering where the day went.
When I was in my early teens, my friends and I used to play a board game called “Diplomacy”, which is kind of like “Risk”. In both games, you wage long imaginary wars over Europe.
This became significant in the 8th grade, when our entire class was given a surprise spot quiz to see whether we could identify the locations of the countries on a map of Europe. Those who got the answers right could opt out of needing to take a class on European geography.
Everyone in my circle of friends got all of the answers right. Everyone in the rest of the class flunked the test, except for the Catholic kids. They had apparently learned the same thing in their weekly after-school parochial school.
It seems that these two very different groups shared the same special knowledge.
Some days are completely unlike all the other days. This has been one of those days.
Come to think of it, all days are like that.
Recently a colleague and I were discussing the distinction between genotype and phenotype for synthetic objects. Two virtual objects can both be chairs, but look very different.
This is important, because in both cases, virtual humans would know that they are things to sit on. And this generalizes to virtual tables (things to put stuff on), walls (things a virtual human can’t walk through) and windows (things a virtual human can look through within a wall).
When you model a virtual object, it is useful to identify its genotype. This not only helps when using it, but also as you continue to refine its appearance.
No matter how you modify the appearance of a virtual chair, it should still be able to function as a chair in your little virtual world. And no matter how you modify your virtual human, you still want that virtual human to be able to sit down on any virtual chair.
It may seem like these sort of rules will add lots of constraints. But it turns out that having those constraints actually makes everything easier.
Every once in a while I get new toys. I guess I should qualify that.
These are not “toys” like when I was seven years old. They are actually various kinds of professional equipment.
In just the last few weeks I’ve gotten a fancy new VR headset with gaze tracking, a camera that senses both color and depth, and a pair of gloves that accurately tracks your finger movements. I’m using it all for work.
But still, they are toys, if I am being honest. I love creating things in computer graphics and animation, and every new piece of equipment allows me to do that in new and exciting ways.
So this is a nice case of professional productivity coinciding with fun. The more fun I have, the more I get done.
OK, maybe these are toys like when I was seven years old. 🙂
Giving demos is very good for my process. You would think it an imposition to give a demo every day, but it turns out it is quite the opposite.
Every time I give a demo, I learn something new. Usually it is something that I need to fix.
The process of “performing” my software turns out to be a key part of successful development of that software.
Good thing there are people who like watching demos!
Until now being physically co-present with another person has been the gold standard of communication and collaboration. But in the last year we have been forced to experience alternative interfaces for working together remotely, albeit primitive and imperfect.
I am sure that the makers of these interfaces would like its users to think “Hey, this is almost like being there!” Alas, we are still quite far from that point.
The tragedy of the pandemic has spurred a lot of smart people to think in new ways about how to work together remotely. This process of invention and discovery will continue in the years to come, and will be far more mature in, say, another ten years.
I wonder if we will get to the point where physical co-presence is no longer considered the gold standard. At that point, perhaps people working together will prefer the latest and greatest remote interface to reality itself. They might even look at the person sitting right next to them and think “Hey, this is almost like not being there!”
Thinking about old songs yesterday got me thinking about songs in general. Why do songs work?
If I were an alien being observing humans from outer space, it is not clear that songs would make sense to me. There is something odd and irrational about the appeal of a song.
The music that drives a song seems to be something parallel to emotion expressed in language, yet clearly different. Music is nearly universally appreciated, yet the exact nature and cause of its appeal defies easy analysis.
And the best song lyrics are often highly oblique. They suggest without defining, painting an impressionistic landscape of words and ideas that we the listeners are left to fill in.
Why does this combination of words and music have such an enormous appeal to us human beings? It clearly doesn’t have the same impact on cats and dogs.
And I suspect that those nosy aliens would be mystified as well.
