Augmented Reality Billiards

scubacuda writes: "Wired.com reports that Columbia's CS Department has designed a new gadget designed to "take the brainwork out of billiards" and help the average player eventually take on professional pool sharks. The Stochasticks consists of a 5-by-10-inch laptop carried in a backpack, a half-centimeter-by-1-inch long lipstick camera and a headset. Pool experts, such as Mike Spinkle, president of United States Poolplayer Association, say that this device makes it easier to visualize the angles."

Hmm ..

[grokBoy]

do you think they'll notice in competitions?

What's hard about visualizing angles?

[Anonymous Coward]

Of course when you see an angle you only see a projection of it. For each infinitesimal angle dtheta, you have to compensate perspective by dividing by the triple-product of the vector from the angle to your eye, the vector normal to the plane spanned by the angle, and the vector in the direction of dtheta (all normalized). It you integrate this over the whole visible angle, you can easily evaluate the real angle in your head.

Maybe this will help me be able to keep from missing the cue ball so often.

awkwardness

[rob-fu]

Jebara did admit that there are times when the Stochastick could be awkward. "If you're in a Harley Davidson bar where the people may not approve, you may want to be very discreet about wearing a computer aid."

Well no shit. But then again I don't see many geeks going to these "Harley Davidson bars" in the first place.

Also, your chances of meeting girls diminishes even further with one of these things. Leave the Stochastick at home!

Connor: The 500 series had cameras on their heads. We spotted them easy. Also they were tethered to a wall, and deadly only at pool.

Re: But do those angles actually exist?

[User 956]

It is true, that if you integrate this over the whole visible angle, you can easily evaluate the real angle in your head. However, we do not accept, nowadays, as it happened in the past, that our perceptive world is just the plain result of an encounter between a "naive" brain and the physical properties of a stimulus. Actually, perceptions differ, in quality, from those physical characteristics, because the brain extracts an information from the stimulus and interprets it, according to previous similar experiences.

We experiment electromagnetic waves, not as waves, but as images and colours. We experiment vibrating objects, not as vibrations, but as sounds. We experiment the beards of linux hippies, as they blow softly in the wind. We experiment chemical compounds dissolved in air or water, not as chemicals, but as specific smells and tastes. Colours, sounds, smells and tastes are products of our minds, built from sensory experiences.

They do not exist, as such, outside our brain. Actually, the universe is colourless, inodorous, insipid and silent. Therefore, we can now answer one of the questions of traditional philosophy : Does a sound exist when a tree falls in a forest, if nobody is present to hear it ? No, the fall of the tree only creates vibrations. The sound occurs if vibrations are perceived by a living being.

Information from the environment or from the body itself, is picked up by the sensory systems and utilized by the brain for perception, regulating corporeal movements and maintaining arousal. A sensory system starts to work when a stimulus, usually from the outside world, is detected by a sensitive neuron, the first sensorial receptor. This receptor converts the physical expression of the stimulus (light, sound, heat, pressure, taste, smell) into action potentials , which transforms it into electric signs.

From there, the signs are conducted to a nearby area of primary processing, where the initial characteristics of the information are elaborated, according to the nature of the original stimulus : colour, shape, distance, shade, etc. Then, the already modified information is transmitted to zones of secondary processing in the thalamus (if originated by olfactory stimuli, it is processed in the olfactory bulbs and then directly conducted to the medial area of the temporal lobe).

In the thalamic zones, older data, originated from both the cortex and the limbic system and containing similar experiences, link to the new information, in order to form a message, which is carried to its specific cortical centre. There, the meaning and importance of the new detected stimulus are determined by a conscious process of identification called perception.

Although two human beings share the same genetic and biological architecture and function, perhaps what I perceive as a dintinct color and smell is not exatly equal to the the color and smell you perceive. For example, you may like a certain Thinkgeek T-shirt with a pseudo-pithy statement about emacs on it. I may think it's lame, and that it clashes with your beard. We give the same name to this perception but we cannot know how they relate to the reality of the outside world. Perhaps we never will.

How to kick azz at pool.

[rice_burners_suck]

This is the stupidest thing I've ever heard!!!

It's like the Sprite commercial. "You wanna play all-star basketball? Practice. You want a good friggen soda or whatever? Drink Sprite." I like that one because they're not trying to advertise that drinking Sprite will make you an all-star basketball player or whatever.

So you wanna get good at shootin' pool? Go to a bar that's got pool tables, see, order a pint of Negra Modelo, walk up to the nearest chick who looks about 30 years old, and ask her to shoot pool with you. Go to the pool table, drop a bunch of quarters inside, take a huge gulp of Negra Modelo, and then start playing. Yeah, you're gonna lose, because all 30 year old chicks who hang out at bars kick ass at pool. But play about ten games or so, and when you finish your pint, get another one. As you get progressively more drunk, your accuracy will increase, and your embarassment at sucking so bad will decrease. Do this about two or three nights a week--ask the chick which nights she hangs out there, because all 30 year old chicks at bars hang out at that bar on certain days--and before you know it, you're a pro. No need to cheat.

Oh well... does anybody ever listen to ME?! Not until it's too late. Ooooooooooooh well.

Aah. He's from MIT. He's just jealous that he didn't invent it first.
