For those who don’t know him, John Carmack II is one of the premier game programmers. He was a co-founder of id Software, which you may have heard of. Among his credits as lead programmer are Wolfenstein 3D, Doom, Quake, Rage and their sequels. And he’s the founder and lead engineer of Armadillo Aerospace.
In this article for #AltDevBlogADay, he discusses latency, one of the major problems in VR. Absolutely worth the read.
I managed to get all of the components hooked up around the amps today. Now I have the USB Dolby 7.1 decoder on top of the amp stack, with all four amps bolted together. I’m waiting to get a power strip that I can hook up all the power supplies too. But everything should have a nice blue glow when it’s plugged in. Tomorrow, I’ll hook up the speakers and see how it all sounds/feels.
Not much progress, due to other classes, work, life-in-general. But I have a gap today so:
Meeting at PAD lab to discuss our cohort of projects
I’m going to swing by Home Depot on the way home today to get some .25″-ish threaded rod and nuts so that I can make a tiny rack for all the amps. They also sell Y-adapters, so I’ll pick up a few more of them. Pix by the end of the day, with luck.
Bronchitis sucks. In a wheezy, “I need more air” kind of way. Anyway, the amps, actuators, and a Dolby headset are on their way and should arrive today. I’m going to take advantage of the fact that they are not here to work on getting these creatures out of my lungs.
Not much to report today, except that everything worked the way it was supposed to.
Dolby worked as plug-and play.
The small tactile actuator seems best.
The amp is powerful.
Java3D talks to at least two channels
So the next step is to get three more amps, six more actuators, and some kind of headgear. And maybe some kind of rigid helmet to attach the actuators to? I’m thinking I can use one of my old bike helmets to start with.
I got my amp (2 channels) and USB Dolby 7.1 adapter from Amazon last night and wired up the transducers this morning, hoping to make some vibrations this evening. However, I forgot that I needed to get the sound *from* the Dolby unit *to* the amplifier. Oops. Looks like a trip to radio shack tonight. And no work on this tomorrow, since I’ve got class.
Example methods and systems for displaying one or more indications that indicate (i) the direction of a source of sound and (ii) the intensity level of the sound are disclosed. A method may involve receiving audio data corresponding to sound detected by a wearable computing system. Further, the method may involve analyzing the audio data to determine both (i) a direction from the wearable computing system of a source of the sound and (ii) an intensity level of the sound. Still further, the method may involve causing the wearable computing system to display one or more indications that indicate (i) the direction of the source of the sound and (ii) the intensity level of the sound.
