For the last question, it may be more if an issue with Nolo’s driver than anything else, basically touching the edge of the actual trackpad doesn’t emulate he edge of the vr controller’s teackpad because the scaling is off.
For the first question, I ask because both the nolo and the hydra have excellent controller oriention, but have major controller position flaws. Nolos is controller occlusion because of the single base station and the hydras suffer from an odd warping effect as is passes around the base station due to its magnetic field tracking. It might not be so useful in the end, though.
