Rotating a hologram in smaller increments

I've been trying to orient several holograms to the real world, but unless I'm doing something wrong, the rotation control doesn't allow for precise adjustments. It seems like for every "click" of the control sphere, the hologram rotates several degrees. Is there a way to limit the rotation to one degree per click, or enter the desired rotation amount using the virtual keyboard?

Howdy Nelway,

Hologram placement controls can be interacted with using direct touch or indirect hand ray, as expressed in the documentation link I've shared below. Which method are you using, direct touch (grab the blue controls with pinch) or indirect (point your hand laser at the control and pinch to grab)? Both methods respond to the amount of movement from your own hand, so if you move very little, it should rotate very little. If you move your hand in a larger motion, there will be a larger rotation.

There is currently no incremental rotation control, only near/far gesture interaction.

While "single click increment" is not possible - it is already possible to execute very small rotations today. Please try a grab and release method for your input. The 3D placement controls are intended to be "pinch and hold" until you have the object where you want it, then "release" to leave it there. So just taping once will definitely give you unexpected results and I recommend grab and release interactions for this system. Under grab and release conditions, you can be very precise in your rotations. You can grab and rotate either way back and forth, before releasing. You can also move your body physically while holding the grab in order to better see your alignment from multiple perspectives. Let me know how that works!

Hi Andy,

Thanks for providing feedback. In answer to your question, I've been using direct touch and indirect trying to get the holograms to line up as close as possible to the real world. I work in the transportation industry, and the challenge I'm facing is overlaying the larger holograms (electrical networks) to the actual vehicle. In some cases, the peripheral components in a 3-meter radius move a distance of 5.2 cm for every degree of rotation. I'm finding that using the available rotation methods do not provide enough accuracy. It would be great if there was an option for adjusting the rotation settings, or using decimal degrees for rotation.

Thanks Nelway, that's really clarifying for me. I empathize with you; indeed rotation of larger objects with this input system is trickier due to "the lever arm effect" where smaller input at a centerpoint results in larger rotational impact at extents of the 3D object. Below I list several ideas you can try to work around this in the meantime. I understand these may not be possible for all scenarios, but hopefully we can get you feeling a bit more successful while we prioritize incremental rotation. We are starting to hear this feedback more as customers create and position larger holograms. The system you're using today was built with the 3D Toolkit shapes in mind, which are never larger than a basketball. I will ensure your voice is heard when we do feature planning, as this is definitely a limitation currently, and I'm sorry about that!

1.) use indirect input while standing as far from the object as possible - this may dampen your movement significantly enough to aide in precision - and we resize the controls so they'll still be easy to hit, even if you're on the other side of the workshop. I recognize you may not be able to judge the mixed reality alignment from there, but please try and report back!

2.) segment your 3D objects into smaller shapes that are less susceptible to the lever arm effect. I recognize that this is more work importing and placing content, but perhaps you can find some benefit here in the ability to re-style the holograms in a more localized manner when the objects are split, or find value in focusing your user only on the part of the wire that may be meaningful on that step, sequencing the next part of the wire to show on the next step?

3.) there are some more advanced work arounds in the data model through your web-hub, but I think we should be careful about that type of manual data modification unless you're quite confident in the power platform and doing programatic adjustment to your database. I recognize that this workflow is not as fast, however you can make the changes on the webhub and see them update live on the headset.

Thanks for your suggestions Andy, I tried the indirect touch standing farther away from the vehicle and it helped. The hologram overlays still do not align with the real-world objects in the vehicle, but they get the point across. I think it will have to work for now.

I'm not sure I'd like to break the 3D models into separate holograms, to then import them into Guides for final assembly (sounds like a lot of work). We have to work with multiple network layouts with optional configurations. Users need to see the complete routing of lines, so splitting the network into sequential steps is not feasible.
