I am thinking of a project i want to make, which the user will move the mouse of the computer just by thinking it. So from the little stuff i know about this, i need something that converts your thought into a wave. What devices are doing that? Is there something else i should keep in mind? I am really excited about this but i can't find a lot of things online. Anyone who knows anything about neuroscience in computing (even not related to this question specifically), please write it here. Thanks in advance.

  • There aren't ready made solutions for this. Very much still an experimental field at the bleeding edge of neuroscience. There are devices that can detect electrical waves, but they aren't cheap and to make one yourself would require a really solid knowledge of electrical circuits. This wouldn't be a simple feat for someone with a PHD, much less someone unfamiliar with the topics. – Chase R Lewis Jul 03 '17 at 22:15

    This is not a notice-board / forum type site, you should only ask a specific question in the hopes of getting a specific answer! Not only that, but your question is broad enough to write a PhD thesis on, let alone a short reply on *any* website... – Wolfie Jul 03 '17 at 22:15

  • well i was thinking isn;t it possible to make a simple program to move the mouse to the right by making an array with 50 electrical waves, all of them created when thinking a right arrow, and somehow find the average wave and then whatever user thinks of a right arrow, the mouse will move to the right? Sorry if my question is stupid.. – paulaxa1 Jul 03 '17 at 22:42

You can obtain signals corresponding to motor functions for example, using EEG, and process it further to obtain desired input to your system. That would be a starting point, but like the other responses suggest, it is challenging.

  • sorry for late reply, and thanks for your feedback. I got started to it. We will see. Fortunately i have one year for my BS thesis, so even if i won't make this work, i will have time for something else. :) – paulaxa1 Sep 17 '17 at 11:32
  • Good to hear that. In my BS I did a similar thing for one of my courses. The difficult part is to obtain an EEG machine for the project, which, in my case was available in one of the university labs. These days EEG has become lot cheaper and portable though, so it should be feasible for you I guess. – Salman Sep 17 '17 at 18:58
  • You might want to start reading about brain-machine interfaces (BMI). – edgarbc Nov 18 '20 at 00:35
