I had a curiosity that how things work. This time I have this doubt. How internally remote control in Zoom app works.

I'm getting pretty bad results with Area Learning, the localization takes very long and I have no idea what's happening. Did I map the area enough? Is there enough landmarks? Is the ADF alright? No clue.
Is there any way to provide a visual feedback while doing the actual motion tracking and area learning? I keep seeing it in Google videos but didn't find any way of doing it in the Unity SDK.
I would like something like this in my video overlay: https://youtu.be/NTZZCtmR3OY?t=10m57s
Btw my results in Unity are FAR worse than this demo, sometimes it takes minutes for the device to localize and only at a certain spot in the room, the next minute the very same spot doesn't work again. Quite frustrating. No idea what app the presenter uses, for instance, my ADF Inspector reliably crashes every time I try to load any ADF. (Using Wasat and recently I've deleted and re-installed everything.)
It is not supposed to be so. It should not be that bad, under the normal day light condition. If it is a small area, should be able to localize using ADF within 3-5 seconds. The video showed the usual case -- always like this.
If your kernel is up to date, and you are using the correct development kit. I would recommend you to reach the tango team customer service directly.

Perhaps it is caused by your device defective. If so, ask for an exchange would solve the problem.
I have a script that uses Balloon Tips to alert users to progress. However, by default balloon tips make an annoying noise. In a perfect world I would be able to set my balloon tips to be silent, while leaving any other alerts to behave in the normal way. But I don't see anything along the lines of $balloontip.balloonTipMute=$true.
My second thought was to mute the machine for the duration of my test, and I found this thread that seems to be what I want. However, the Core Audio API approach Alexandre mentions is not working for me, and the simple SendKeys approach doesn't work if the machine is already muted, as in that case I turn sound on right before proceeding to annoy the snot out of the user.
So, starting from the bottom, is there a way in PowerShell to see if audio is already muted, so I can toggle only if needed? Or, can someone verify that the Core Audio API approach really should work from Windows 7 on, and I need to start looking for a mistake? Or best yet, is there a secret sauce that makes Balloon Tips silent?
I don't see any way to start/stop profiling in Instruments from code, which kinda kills its usefulness for me in a large number of situations.. Am I missing something? Does anyone know of a way to do this?
The fallback approach is to grab performance data on my own, without Instruments. Has anyone tried to do this before? By "performance data" I mean counts of events like cache misses, fills, missed branches, etc.
Thanks!
Update:
I looked into operating the performance monitor hw directly from code, but, unsurprisingly, it appears to be a no-go. USEREN, the "user enable register" controls access to perfmon registers but is not enabled. It might be possible to run privileged or enable user access with a jailbroken phone, but that's a lot of work for some basic profiling.. ugh.
Is there a way to simulate user activity on desktop on Windows? This is the situation: A friend of mine works from his home. His company recently decided to provide their employees with a communication tool which they have to keep running in the background. Apart from its main functionality it also has a very intimidating side effect: It tracks user activity. This means that the programm monitors keystrokes and mouse movements. If a user is idle for say 5 minutes or something, an icon next to his name indicates his idle status to all other users, much similar to instant messengers like skype for example. Now while this may be useful in IM programms, we both find it a bit disturbing in a work related context, for obvious reasons.
Doing some google search only gave me shareware links or cheating tools for MMORPGs. But maybe I searched for the wrong terms. My first guess would have been to have a small process running in the background which imitates keystrokes or mouse movement in regular intervals. But maybe there is another way to deal with this. (Oh, and complaining about lack of privacy to the employer is not an option ;) Also please note that I don't want to promote laziness or question an employer's rights over his employees.)
Any comments and help appreaciated. Thanks!
There is an easy way to make cursor move in C++.
its something like:
pos.X = 10;
pos.Y = 10;
I dont know if this is the best way, but it works.
If you dont want to program your own program, Im sure there are a lot of programs on the internet. You just need to google :) .
I'm trying to get data from a server. Right now, I am polling the server every couple of seconds for the current values. I am wondering if it is possible to have Matlab get the data in real-time or if I am stuck with my current implementation. Has anyone done anything like this? If so, maybe you can tell me how you got started with it.
Any help would be greatly appreciated. Thanks!
If you're on Windows, you can listen to ActiveX (COM) events using REGISTEREVENT. You would need to provide an ActiveX control (servers might work too, I'm not sure) that triggers the event, which would invoke your MATLAB function.
Matlab timers work well for periodic events. You'll want to be careful about making sure your function executes in less time than the periodicity of the timer, though settings for the behavior when that doesn't hold do exist.
