Summary of Publication:

> Parametric spatial audio rendering is a popular approach for low computing capacity applications, such as augmented reality systems. However most methods rely on spatial room impulse responses (SRIR) for sound field rendering with 3 degrees of freedom (DoF), i.e., for arbitrary head orientations of the listener, and often require multiple SRIRs for 6-DoF rendering, i.e., when additionally considering listener translations. This paper presents a method for parametric spatial audio rendering with 6 DoF based on one monaural room impulse response (RIR). The scalable and perceptually motivated encoding results in a parametric description of the spatial sound field for any listener’s head orientation or position in space. These parameters form the basis for the binaural room impulse responses (BRIR) synthesis algorithm presented in this paper. The physical evaluation revealed good performance, with differences to reference measurements at most tested positions in a room below the just-noticeable differences of various acoustic parameters. The paper further describes the implementation of a 6-DoF realtime virtual acoustic environment (VAE) using the synthesized BRIRs. A pilot study assessing the plausibility of the 6-DoF VAE showed that the system can provide a plausible binaural reproduction, but it also revealed challenges of 6-DoF rendering requiring further research.

Magic Leap Patent | System For Detecting Six Degrees Of Freedom Of Movement By Tracking Optical Flow Of Backscattered Laser Speckle Patterns

This is my side project that started as a Linux Game Jam 2019 entry. It's a basic six-degrees-of-freedom shooter (think Descent from 90s or Overload) in a procedurally generated maze where your goal is to take out all sentry guns as fast as possible.

I'm currently not sure what to do with this game. My main project Hyper Ultra Astronautics is releasing soon, so I could put more effort into this game or start something completely new. There's no lack of ideas :)

Here's a screenshot and a download link.

I'm looking for feedback on two things especially:

• Are the controls (see readme.txt for help) good and if not, what should be changed?
• Is the game fun to play? Obviously its very early version, but can you see the potential?

Any feedback will be appreciated.

I don’t get the ending that much?

I have been playing the Battlefront 2 beta and I can't fly for shit because i keep relying on being able to dodge around things which you cant, forward only. its so annoying and after hundreds of hours in ED i just cant retrain my brain haha. so thanks ED for having an awesome flight model that no other game can match!

Ships have six motions these are know as degrees of freedom. Three are linear, heave sway and surge. Three are rotational, pitch roll and yaw. https://en.wikipedia.org/wiki/Ship_motions
Spacex have fitted 4 thrusters and a GPS control system to their barges turning them into ships. I would expect this control system to allow the control of sway surge and yaw. Do they or could they control the other three degrees of freedom; pitch, roll and heave? If not how could they do this? Elon recently said the first stage had to be within 10% of upright and the sea was causing the drone ship to pitch / roll 3%. Add to that the wind factor and it seems to me controlling the six degrees of freedom could be critical to a successful landing.

Hi /r/VIVE, We have been working hard over the past several months to bring you Wizard Ball VR, a British Wizard school sports game inspired multiplayer VR game. Use teamwork and tactics and the occasional spell to score goals against the opposing team while flying magical broomsticks.

We have done a few tests of this game already thanks to the wonderful people in this sub helping us out and now we are ready to record video with a bunch of players so that we can make a trailer video for the Steam store page!

If you would like to try out our game, email us at nrvr.canada@gmail.com and I will provide a link to our Beta version of the game a couple hours before the test. The test will be today at 8pm Eastern daylight time (Toronto time), about 6 hours from this post. We have a countdown timer and video of a rather old version of the game at http://nrvrdev.ddns.net . We are hoping for 10-20 people to fill a server or two so that we can capture game play footage. If we fill one server we will host a second game to fit another group.

Thanks!

EDIT: Links to a download of the game will be sent out a few hours before we start up the server.

We are expecting to be running the server(s) for about an hour after we start up.

All feedback will be appreciated but I'm especially interested in hearing your thoughts on the Android version. As you can imagine, designing good touch screen controls for a full six-degrees-of-freedom movement is near impossible. I tried anyway and now I need feedback to help decide whether to continue or give up on the mobile version.

Sensor System – Hand Gestures

Microsoft's patent FIG. 2 below is a block diagram of an example input device (#200). The input device (#100) of FIGS. 1A-1D above may implement at least some of the components of the input device. The input device may include a sensor system (#202) for sensing manipulation of the input device in physical space.

The sensor system may sense motion of input device #200 with six degrees-of-freedom: three degrees of translational freedom (e.g., along orthogonal x, y, z axes) and three degrees of rotational freedom (e.g., about orthogonal x, y, z axes).

The sensor system may assume any suitable form, such as that of an inertial measurement unit (IMU), and may include one or more of an accelerometer, gyroscope, and magnetometer. As another example, sensor system may perform six DOF sensing based on alternating current electromagnetic sensing technology.

The input device #200 is operable to sense gestural input. The sensor system may include a gesture sensor for sensing such gestural input. The gesture sensor may include capacitive, resistive, optical, acoustic, and/or any other suitable sensing technologies.

Alternatively or additionally, an image sensor external to the input device may be used to detect gestural input supplied in relation to the input device.

To this end, Microsoft's patent FIG. 1D shows an image sensor (#162) coupled to computing device (Desktop #102) and configured to detect gestural input applied to the input device. The Image sensor may assume any suitable form, such as that of a depth camera (e.g., time-of-flight, structured light, stereo camera system).

**Platform(s):PC

**Genre: RTS

**Estimated year of release: 2000-2004

**Graphics/art style: Imagine homeworld, but higher detail. What stood out about this game, is that "follow unit" button you could actually look into the cockpits, and see little pilot models in each ship.

**Notable characters: One unit was a like a (combat spaceship) that would attach itself to asteroids, rendering it underacted by the player (at least thats how im remembering it, they even introduced the ship doing this as a cutscene.

**Notable gameplay mechanics: Its fuzzy, but I recall the game may have went deeper into "mining" but was every bit combat heavy as Homeworld was.

**Other details: Now this was before sword of the stars, and other games that im trying to compare this with. I know for sure it wasnt homeworld (since it you could see cockpits that contained pilots) and it wasnt EVE, but it shared the same timeline as both as i recall.

Find how many degrees you are from Hikaru Nakamura with your chess.com username

Due to the previous post getting 1k upvotes, I promised I would upgrade the algorithm for greater accuracy so here it is.

Using the chess.com api I have created a database of 80 000 users with their routes directly calculated from Hikaru (only had to leave my computer running for 3 days straight).

For example my account FuzzyLogic12 the path by wins to Hikaru is:

FuzzyLogic12 (1578) --> AxDelgado (1400) --> UniqueTealeaf (1843) --> IvanKovalenko0406 (2109) --> Hikaru (3221)

Making me 5 Degrees of Hikaru in bullet

I am not associated with Futuremark, but this game is, unfortunately, slowly dying off and I still want some people around so I can play!

Shattered Horizon is an amazing game that you can get on Steam for about $20, provided you have Direct-X 10 (Vista or Win7 only).

This game is not your typical FPS that requires you to have lightning fast reflexes. In Shattered Horizon there’s a lot of strategy in even just your movement. Every time you boost to change direction, you light up like a Christmas tree so it’s best to pick a direction, boost, and drift though the shadows. Maybe lay down some ice (like a smoke grenade) to cover your path from snipers.

A new map pack was recently released and a new weapon pack is about to be released- all free upgrades to the original game, so it’s a good value for money.

There’s still enough people online to play a good few rounds, but usually only one server is ever filled. I guess some people don’t have the best spatial-perception and never get used to an environment with no “down”.
