Hello everyone! I have been working with Sebastian trying to do whatever I can to help the project along. There have been many new developments. We are trying to open up the discussions to the entire community.

For now, the main interface for controlling the camera is the ElphelVision software. There are probably going to be manual controls and a few other ways to manipulate the camera in the future. However, for now we are focusing on ElphelVision as the main interface for the camera. In terms of hardware, ElphelVision will be manipulated using an 8.9" multi-touch touchscreen display with a resolution of 1024x600 mounted onto the rails of the camera.

So folks, we are in the process of completely revamping ElphelVision in preparation for a major next release. I have been working on the interface and have a few mockups to show you. Right now I have only mocked up the main screen of the viewfinder. When I finish more I will post them. The images attached to this post are what I have completed so far. Please let me know what you think.

You can of course also use different screens at different resolutions/sizes. I recently purchased this: 8.9" 1280 * 768 LCD CHIMEI 8.9" 1280 * 768, N089A1-L01 + Pixelworks338 Controller - DIY-Beamer (http://diy-beamer.com/product_info.php?language=en&products_id=129&XTCsid=7ef5b0b7622ca19a6945c1c1332d988d)

But the layout of the java GUI currently revolves around a 1024x600 pixel canvas, in the future it might auto adjust to different resolutions or you will be able to select the layout in the menu.


Now on to my feedback to the interface itself:
-) I love the icons and text size improvements, what options do the left hand symbols link to?
-) currently the text in the buttons is in a single line like "Shutter 1/48", I like this 2 lined design much better!
-) Careful with "Exposure", I think what you are refering to is "Aperture" which is a feature of the lens not the camera.
-) The slider-area inside the buttons seems really small, I am not sure if you can do fine tuning of parameters with this little room to move.

Of course you can also use different screen sizes. I made the entire layout (except for the viewfinder image) vector specifically so it could resize to fit different resolutions :-)

I will have more mockups in the next few days. The symbols on the left represent "Playback/Browser", "Peaking", "Color/Looks", "Guides", and "Magnification Loupe"

I'm glad you like it. The kerning of the text is a tad off and it should be thicker but its good for now.

-) Careful with "Exposure", I think what you are refering to is "Aperture" which is a feature of the lens not the camera.

For some reason I was under the impression that the sensor also had an exposure reading. Or maybe I thought it would control the lens exposure? I don't know what I was thinking I will take it out.

-) The slider-area inside the buttons seems really small, I am not sure if you can do fine tuning of parameters with this little room to move.

I was thinking about this. Ultimately, as long as there is a dot to let you know where to place your finger it doesn't need to be all that big. What really matters is that the little speech balloon above the slider remains visible. I do see your point though, I will make it bigger.

Look forward to some more mockups soon, thanks for the critique!

Here is a mockup of the clip browser. It is a work in progress. The functionality to sync videos with the host computer will be below the metadata/exif tags in the Information box. More to come shortly!

EDIT: If someone could chime in and let me know what they think. I notice that I left the camera controls down at the bottom which seems like just additional clutter. Should I take out the camera controls or do you think they should remain accessible from the playback screen?

Very nice concepts Jeremy!

Here are some ideas I have about the interface:

-Imagine yourself under the worst circumstances when using the camera. This would be either in bright sunlight or on a dark cloudy day. Using a touchscreen interface, you don't want to hit the wrong button, just because you can't see the screen well enough (reflections etc) So I think the buttons can be as big as possible. I use a 7" touchscreen tablet PC with 'only' 800x480 res.

-I've also discussed a 'portrait mode' some time ago. This is where the rods support is designed around. The idea is to put the screen vertically. You'll end up with a smaller preview image, but a lot of space below for controls and other things like focus info or whatever.
Something like this (old concept but you'll get the idea) http://www.dvinfo.net/forum/attachments/apertus-open-source-cinema-project/11499d1238105949-high-definition-elphel-model-333-camera-screendesign-01portrait.jpg

-Another idea: we will probably have an option for an optical viewfinder in the future. If one decides to use only the optical viewfinder, the interface could have a function to disable preview. Maybe only refresh the image when you adjust a setting (exposure etc)
Or use a graphic gadget like a replica of an old exposure meter in stead of the preview image :-)

The last idea makes it possible to use low end controlers like tablet pcs that can't keep up with the preview image.

Thanks Oscar! I'm glad you like them.

I was waiting for someone to bring this up. LCDs for cameras such as the RED and SI-2k are made to have wide viewing angles and be very bright to ensure even on the sunniest or foggiest of days the display will be visible from all angles. In addition, many LCDs used for film production have sunshades. This is something to consider when selecting a display to use as the viewfinder for a camera.

I designed this interface for use in a certain configuration (1024x600 or greater touchscreen that is around 8"). While designing the interface I made a conscious decision to design it with film makers in mind. It is designed to be the main control element of the camera (replacing many manual controls) similar to cameras such as the SI-2k. That is why I designed this configuration with a 16:9 aspect ratio in mind. The entire interface is strictly vector for a few reasons. First, so it could be scaled nicely to different resolutions. Secondly, to allow for a wide array of possible configurations. I have not mocked up the settings interface but inside the settings interface I wanted to add an option to change the configuration of the interface. There could be options for "portrait mode", when using the screen vertically, as well as an option for "headless" mode which would eliminate the preview screen. These separate configurations could be created on the fly by dynamically resizing the elements (thanks to the flexibility of the vector interface). Does that make sense? I promise my idea will be clearer once I finish all the mockups.

Oscar, on a sidenote I would appreciate it if you could email me all the 3ds max files you created for the prototype. I am using Cinema 4D though so you would need to export them as .3DS (which is compatible with cinema 4d).

FYI:
I have stopped working on the ElphelVision interface momentarily so I can lay out the prototype camera in VariCAD. I will resume working on the UI once enough of the prototype has been finished.
