While those devices are far from perfect they are an evolutionary step in how people are able to interact with technology. My mother in law does not use a computer or smartphone at all, but she loves to use the Echo because it provides a fa

In my car case it was a know issue of this model and repaired for free within one hour. And while a degraded battery is nothing that needs to be replaced for free, the manufacturer of the phone probably sunk a lot of time and money into dev

I can't tell how well it's executed but the major issue I have with this is that this is not properly communicated to the user. I guess most people already get the feeling that their devices slow down after time, or the new apps&#

Why do you know that photos are not enough? If you have good enough photos you can produce higher resolution 3D models than with a Kinect like depth sensor (which in the end is just a stereo "camera" anyway). And since the Face

I don't think luck in this context is actually a thing that happens by chance but rather by actively finding and selecting the right choice presented to you at that time. I've seen it with myself and many of my colleagues that the

Can't resist: "The only winning move is not to play" :) But I guess it means that a winner knows when there is no path to a win and retreats to do something where it is actually possible to win.

If I am playing streaming music and have other people in the car who want to listen as well. I could unpair them and then pair it again when needed, but I hope that is not how it should be done.

Point taken :) In the car they are used as a hands free kit. My car radio can be used to do calls as well but the headphones, only in one ear while driving, do have much better call quality

I'm not sure we are talking about the same bluetooth here. I have yet to see a bluetooth device that just works (I am a non apple user, so I can't speak for IOS devices). The worst example are my wireless headphones. When I get in

How long does the extracted supply last. As far as I was able to discern from the article, more stem cells are grown and banked, so if they would be used for several future treatments is there a way to ensure that they last or is it over af

Millions is not a problem. For billions is probably too slow or you run into memory issues.

This was the reason why we initially started this project. This was back when the HDL-64E cost around $72k. It supports the LIDAR with 64 and 32 lasers, but it also has a generic mode where you can set an arbitrary configuration of lasers (

Sorry for the self advertisement, but I think that it fits really well. If you are thinking about creating annotated point clouds you could use our software (also based on blender): http://www.blensor.org/ It virtually scan

But wouldn't a lower frequency be at the cost of spatial resolution due to the longer wavelength?

Thanks for that explanation. What would happen with the quartz crystal. Would it just not emit the sound or would it crack under the vibrations? And if it can't withstand the vibrations it generates, how far off would it be from the re

I have no idea how hackernews always reads my mind about this kind of things but I started thinking about this topic due to a personal interest a few days ago. And my question is. Can the ultrasound probe be made of off-the shelf parts. I t

Yes that definitely qualifies. Thank you for sharing.

Inteliclinic is open sourcing their new EEG sleepmask. This could be a relatively low cost tool for quantified self enthusiasts. I do own the predecessor and was hoping to be able to use it for my own developments. It seems the Neuroon Open

Are you sure you mean doppler shift and not just phase shift due to the distance the light traveled? AFAIK the Time of Flight cameras like the ones from PMD use the phase shift with the obvious problem of the calculated distance being ambig

Simple answer: simplicity Our world around us is 3D. A camera projects this information onto a 2D plane and throws away a lot of information in the process. When we move in the world we need to know where obstacles are relative to us. We in

You don't need to engineer it. In our lab tests we accidentially realized that one of our desktop computers was "invisible" to the Velodyne, because it had a black case. Every material that is black could be a good candidate.

I am not 100% sure about that. At the moment it is basically impossible that there is interference from another LIDAR due to the fact that there are so few. but if every car, motorcycle, drone and whatnot is equipped with several LIDARS the

There is work on self driving trains. In our university we worked on a project called autoBahn which made a proof of concept self driving train and I know of a few other research projects that worked in the same direction. However, in my op

Well you can use it on Android as well, but it is a bit tricky to do on non rooted devices. I did a proof of concept a while ago ( http://www.ferienvillaflorida.de/labs//3d/android/stereovisi... ) but ne
