Usage Guide

For students who have access to the lab. This means that a member of the lab staff has:

  1. Added your name and reason to the lab access list, which is then printed out and given to the Paabel administrator.
  2. Given you edit access to the lab’s Google Calendar.
  3. Included your e-mail in the lab’s e-mail list.
  4. Added your UT username to the lab’s user group.

Here are guidelines for using the lab:

  • When you use a part of the lab or specific hardware, then mark it as an event in the Google Calendar. See the example on the right. This is so everyone else knows not to book the same hardware or area of the lab for the same time. Make sure you add the event to the lab’s calendar, not your own personal one.
  • You have access to the lab on workdays from 8:00 to 20:00 and on weekends from 10:00 to 18:00. That is the time the administrator is in and you can get a key from her. On other times you need a member of the lab staff to accompany you. Some of us work in the evenings, so that is entirely possible.
  • When you get the key from the administrator, do not forget to give it back to her before you or she leaves.
  • Log into the computers with your UT credentials. You should have admin access right away. Let us know if you do not.
  • Do not change global settings in the computer without changing them back or leaving a note about it. That includes SteamVR or Microsoft Credential Manager settings. The last one is especially insidious, because other students can not push their Git repos afterwards and there is no notification about the issue.
  • When you take something from the shelves (a book, headphones, VR devices) then put them back to the same place afterwards. This is so that people can always easily find the right stuff they are looking for and so that there would not be arbitrary things on the workstations when the next student comes.
  • When using the HTC Vive, remember to unplug the lighthouses, when you are done. They have moving parts, which should not be moving when no one is using the Vive. Please also refer to the Wireless HTC Vive Guide below. After using the Vive, untangle the cord and plug in the controllers to charge the batteries.
  • When something runs out (paper, pens, sticky notes, candy) or breaks (a cable, a controller), then notify a member of the staff immediately, so that we can restock as quickly as possible.
  • If you need some hardware, which is currently not available in the lab, then notify the member of the staff. We might be able to get it for the lab if it is justified and has a reasonable cost.
  • If you have an emergency, then the phone numbers of the lab staff members is posted on one of the walls in the lab. When you have a general question, then e-mail the list.
  • Have a fun and be productive!

The Plan

Wireless HTC Vive Guide

Using HTC Vive with the Wireless Adapter. Steps to take in order to enjoy the new freedom of movement:

1) Locate the battery pack, usually close to the extended USB-C cable somewhere on the table of CGVR-1. Pray that the battery is full, otherwise charge it through USB-C port with the cable, using one of the USB wall adapters from the motion controllers.

2) Connect the battery to the extra funky looking headset via the long USB cable dangling from the headset. When clicking the power button on the battery, green LED should light up both on the battery and on the wireless receiver (a few seconds later). If the receiver does not light up, click the Vive logo on the receiver (yup, it’s actually a button!)

3) But where is the transmitter? There she be, stuck on the monitor! Even though it looks like a directional antenna, actually the signal bounces around the room, so you can easily also wear the headset while sitting behind the desk (as long as at least one lighthouse sees you). No more rolling your chair over the cable, yes! But basically you can forget about the transmitter.

4) Launch VIVE Wireless app from the desktop. If you skip this step, the headset will not be detected later in SteamVR

5) Launch SteamVR as usual.

6) Wear the headset and manage the battery pack cable so it doesn’t get in your way (probably best to guide it behind your back and hide the extra cable away too). Clip the battery on the outside of your belt or pocket – inside your pocket it will get very warm very fast! Also try not yo yank the cable that go from the headset to the receiver, however tempting it might look.

7) Get lost in VR, battery life should be 2.5 hours on a full charge.

8) After the session take off both the headset AND the battery. Don’t be this guy (gas pump represents headset):

9) Unplug the battery, leaving the long USB cable attached to the headset. Using the Vive USB adapters, the battery should fully charge in 5 hours (having a USB-C quick charge adapter should reduce this time to around 2 hours)

10) Go home. But don’t leave the battery charging overnight, just in case.
