Alpha 7: Using the Rift to Turn Your Avatar While Seated

Rift turns avatar while seated option

Rift turns avatar while seated option

This release adds an option for turning your avatar as you turn your head while in Riftlook. You can configure how far you have to turn your head before your avatar starts turning. This is for seated Riftlook and was developed in conjunction with Tom Willans at the Serious Games Institute of Coventry University.

There are two ways to use this option:

  1. Setting the slider to 0° makes the turning happen all the time. This enables you to look at something then if you continue looking at it, your view will gradually rotate so that the object lies straight ahead and you can thus walk towards it.
  2. Setting the slider to a value such as 45° makes turning start after you look left or right 45° or more. Turning then continues until you look straight ahead again. Depending on the value you set and how flexible your neck is, the effect can be like a gesture that initiates turning.

Something for you to try out; what do you think?

Only a couple of other changes of note this release

  • Changed Rift prediction delta default value from 20ms to 35ms to improve typical perceived latency.
  • Fixed mouselook not being able to turn more than +/-180°.


Release Notes

You can install this version over the top of a previous 1.1 alpha version.

Upcoming Linden Lab Oculus Rift Support

Good news today that Linden Lab’s Oculus Rift support is feature complete and will be released “soon”. Nalates guesses that this will not be before January. I’m very pleased to see that the Lab has spent time optimizing the rendering, something which I intentionally haven’t done in the CtrlAltStudio Viewer on the expectation that they would make significant code changes.

I and other third party viewer developers will be able to pick up the Lab’s code, add in any missing bits and trial feature alternatives, and make it available for use with OpenSim also.

What to expect compared with the current CtrlAltStudio Viewer:

  • Increased FPS.
  • Reduced simulator sickness.
  • A nice UI.
  • I can’t wait!

Rift-specific context menu and show avatar options

This release provides a few miscellaneous additions and fixes, including:

  • Separate Rift-specific settings for showing context menus and the avatar in Riftlook (instead of reusing mouselook settings).
  • Keyboard shortcuts Ctrl-PgUp and Ctrl-PgDn to increase and decrease the walking / flying speed.
  • An option to swap the Kinect’s “fly up” and “fly down” gestures.

Further changes this version are listed in the Release Notes.
