I've also spent the year using my video analysis tool. I have found it most useful for creating transcriptions of the videos I create for teaching. In fact, I'm seriously thinking of creating a standalone app just for the transcription tool itself.
I'm convinced that my video analysis tool is worthy of greater things, so I've begun a serious effort on producing a significant update. I'm beginning with a focus on improving the tool's graphic design.
If you are one of the four people who read this blog, then you know that I've been very honest about my lack of graphic design ability. You also know that I never let it bother me, nor do I let it get in the way of my prototyping. But, every now and then I get some friendly feedback from people who really do find my stuff to be ugly. I usually just smile and remind them "it's only a prototype." This is a sincere answer because I rarely spend any serious time on graphic design. My goal is on creative ideation to build a working prototype of an original design. However, I have a few colleagues around the country with a refined sense of graphic design who are on the record saying that they simply won't use an app or web site that they find visually offensive. If I'm in the audience, I always get the sense that they then look at me from the corner of their eye.
The bottom-line is that I know I have to improve the graphic design of my video analysis tool if I want people to consider using it and (gasp!) consider paying a small amount to purchase it. (Yes I'm thinking of selling it, but with a price about equal to the cost of a breve expresso at Starbuck's.) Given my budget of zero dollars, I can't hire someone to do this work and I don't have the heart to ask some of the talented graphic designers I know to do it for free. Plus, I really wanted the challenge.
Here is my targeted benchmark for success: No one finds the app visually offensive.
It's not that I don't know anything about graphic design. Heck, in my "classic" (i.e. old) book Computers, Graphics, and Learning (1994), I even wrote about graphic design (p. 195-196):
... there are some generally accepted issues and concepts related to visual layout that are relevant at this point. Even the most specific design principles can be traced to one of four broad categories of visual design and layout: simplicity, unity, emphasis, and balance. In a sense, these principles aptly summarize much of the previous discussion of frame and procedural protocol. All four categories can be supported and described on the basis of human perception and information processing. For example, visual layout should take into account a person's abilities and limitations in selectively perceiving the most important information in a given display. All information coming from the environment will be competing for a person's limited attention. Therefore, a display should be designed to maximize the chances that a person will notice the most relevant quickly; it should also be able to sustain user attention over a period of time. When combined with rapid prototyping procedures and a lifelong hobby of "software watching," these principles can help guide beginners in designing effective screens.The principles of simplicity, unity, emphasis, and balance are a good guide, though if you don't have any talent (like me), then you can only expect so much. A very weak area for me is color. I tend to use color in the most simplistic ways and I rarely use anything but pure saturated colors. I usually start with the colors of nature (e.g. green, yellow, and brown, with dashes of red), though when I'm knee deep into prototyping I usually just choose almost any new color when another one is needed. As I prepared to improve the graphic design of my video analysis tool, I knew I had to do more than just "try harder." And, it's not that I don't appreciate good graphic design - I think I "know it when I see it."
Before I share my strategy, let me show you the current draft of my tool's two main screens - the title screen and the video analysis screen (click on either to see them actual size).
Lloyd's Guide to Graphic Design for Those with Little or No Talent
OK, I'm not saying my current design will win any awards, but I hope we can all agree that the changes mark a dramatic and certain improvement. To do this, I followed a simple strategy that I think others also without graphic design talent may find useful.
Step 1: Do a Google Search
I know, genius. It turns out there are lots of talented graphic designers out there willing to share their expertise with you. My starting point was finding a suitable color palette. I did a search using phrases such as "examples of color palettes" and found some very good advice. Here are the two sites that probably gave me the best information and inspiration:
Step 2: Choose the Mood You Want to Project
Step 3: Choose and Stick to a Color Palette
Once the mood and organizing framework is chosen, the next step is to choose colors and graphical objects to implement it. This is where a talented graphical designer can do magic to draw backgrounds for context, characters, and the like. For the rest of us, we might have to use clip art. Either way, a key place to start is to choose and stick to a color palette.
The great thing about the sites above is that they give the color palette for each design in hex notation. This allows me to match the colors exactly. Here were the two examples that really caught my eye:
- Pixels & Aromates: nice browns, with one dash of red
- Kikk Festival: has more browns, with some blues
I've not included a screenshot of either here given that I think this would be a copyright infringement, but you can click on the links yourself to see them. If you do, I'm sure you will see how my title screen was inspired particularly by "Pixels & Aromates." I thought the gradients of brown were warm and friendly. And, for some reason, they evoked a pleasant look of a chocolate milkshake. (Way back when I was trying to come up with a name for this app, I had toyed with the idea of "video milkshake" for reasons I don't remember.) I also really liked the red hue that was used. I decided on using that red for oversized buttons, which may have been too much red. But the color combinations are pleasing to my eye. I made these buttons round to get away from the original boxish look. I also decided that the option to import a source file did not deserve equal prominence, so I de-emphasized that button.
I needed more colors for the analysis screen, so I again consulted the above web sites for guidance. For example, I wanted to call special attention to the video clip controls in the upper right-hand portion of the screen. I settled on two shades of muted orange.
On the analysis screen I wanted to set apart the two save buttons and the one delete button. I used the time-honored (and probably western) tradition of green means "go" or "safe" and red means "stop" or "caution." I also physically separated these buttons to prevent any accidental clicking. (However, I am careful in my user interface design to give adequate warning should an inadvertent click occur.)
One last detail worth mentioning is my use of the golden ratio on the title screen for placing the slightly darker brown band at the top. The band itself divides the large space nicely and the golden ratio (total height divided by height of bottom portion of the screen) of 1.161803 determined how thick to make it.
Step 4: Use the Principles of Simplicity, Unity, Emphasis, and Balance to Create the Screen Design
Probably the biggest change I made was to create a toolbar at the top of the analysis screen using the darkest shade of brown to group navigational buttons and other options. Previously, I had all of these buttons scattered around the screen. The haphazard way these were initially placed mirrored when I created these various options as the prototype of the app was built. I feel this toolbar organizes all of these options very effectively. The other advantage of the toolbar is that I was able to reclaim a lot of screen space. I can now fit a total of 40 tags in the "Quick Tags" window, instead of 24.
I also visually grouped the four main parts of the analysis screen to achieve unity. As you can see from my before and after examples, I really did not make any major changes to the placement of these four areas. But, I made some small, but important design updates. First, I used shades of brown with a thin black border to define each group area. LiveCode has some built in graphic effects, such as drop shadow. I like how this gives the screen some depth. I also made sure everything lined up well for a sense of balance.
As already mentioned, the use of greens, reds, and orange also provide effective emphasis of key areas and functions.
Other Useful Tools
Although you can script colors into LiveCode objects using either hexidecimal or RGB notation, it appears you can only use RGB to "hard code" colors in the inspector window. So, I used this handy Hex-to-RGB converter:
My photoshop skills are also minimal, so I didn't want to spend time creating my own buttons. Instead, I used this web site to create prefabricated buttons:
I did use photoshop to create the stylized text on my home screen, but here is also a web site I found as a fall-back tool:
Although I chose orange and green hues that were part of existing palettes shown in the above web site examples, there are also lots of color picker tools out there to help when choosing new colors, such as the following:
Note about the Windows Version
I mentioned at start of this blog post that most of the negative feedback from my beta tesers has come from the Windows version of my video analysis tool. Although it's great that LiveCode allows for exporting desktop apps to Macintosh, Windows, and Linux, this really is designed as a Macintosh app. Because this app involves video, a Windows user must have QuickTime installed on their computers. Even then, there are problems that have been reported that are simply a mystery to me. I have simply not been able to sufficiently troubleshoot problems on the Windows side. So, I'm seriously thinking of removing the Windows option, at least until I finish with the Macintosh version.
I'm very happy with these graphic design improvements, even though I know I'll continue to tweak the design over the coming weeks. I also enjoyed the process, as time-consuming as it was. If I had the money, I would have much preferred turning this task over to a professional graphic designer. But, maybe this shows that even someone with very limited ability can follow a graphic design process to at least meet the criteria of not making people nauseous when they look at an app.
Of course, if there are any talented graphic designers out there who want to redesign my app for just the fun of it, please drop me a line.
