Workshop Checkin Upgrade #7

Closed tylerhcarter closed 6 years ago

tylerhcarter commented 8 years ago

In order to improve the workshop checkin process, Garrison and I have identified a plan for addressing some of the key issues we've found during the 2015-2016 year. This would be a great project for our programming team, and has a lot of potential for growth and integration with things like Hubot and the website.

Please read the project proposal and give feedback. Also, if anyone is particularly interested in taking over this project, please let me know. Thanks!

I really like the idea, and I think i might want to tackle the project. Should I just start researching now?

tylerhcarter commented 8 years ago

@bobron I think this would be a great project for you to take on. I have a couple idea for making the actual terminal(s) come together, but we should talk about it soon.

multiplemonomials commented 8 years ago

I'd like to work on this too. I think that the biggest question is what language to implement it in. The scanner looks like a keyboard, so we just need to read it as one. Loos like that's doable with Linux's C API.

We don't have to buy a Raspberry Pi, we can just use the Beaglebone we already have.

tylerhcarter commented 8 years ago

@multiplemonomials What languages does the Beaglebone use? If we could make all of this Java across the board, it would make it easier for future team members to modify and hack on.

RonakRoy commented 8 years ago

The beaglebone is like the Rasberry Pi as it runs Linux. We could do it in Java, but having a barcode scanner input might take some time.

tylerhcarter commented 8 years ago

But isn’t there already Java-based code on the Attendance-Scanner tablet to do it? If its just a keyboard, you aren’t really doing anything in terms of image recognition.

RonakRoy commented 8 years ago

I lied. The Java awt package has native key listeners that should work for us.

multiplemonomials commented 8 years ago

Yeah, but Android has a Java API for accessing the keyboard. In Linux, this API only exists in C. We would need to find or write a native library which calls from Java to C.

It would be a lot easier to write this in C++.

RonakRoy commented 8 years ago

@multiplemonomials: I might be wrong, but in Java 7 a KeyListener package was added.

https://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

Shouldn't that work?

multiplemonomials commented 8 years ago

Yeah, but that's a java AWT class. It's for writing windowed apps. We need this to read input from the keyboard when no window is open and there is no GUI environment.

Can we move this to the programming channel of slack?

tylerhcarter commented 8 years ago

You can, but once you've figured out a direction, please report the conclusion to this issue.

Actually, it looks like it might be possible to do this from Java by reading the device-file and extracting the code member from this thing.

But it would still be a pain. I say use C++.
