I had a "my stupid GPS app made me do that" episode of my own.

----

So I had this memory card that I was to borrow from a friend, whose name I cannot disclose here. He suggested he will drop the thing off on his commuter-train ride home in the station nearest to where I live at a certain hour and minute during its short stop there. The idea of this meticulously timed exchange of a "memory device" at a train station appealed to the adolescent in me as it sounded like a spy movie stuff.

My Map app told me it's only an 11 minute drive, yet this being my first mission of this kind, I allowed a few extra minutes, feeling good about my prudence. As usual, my mind was absent during the ride, but the hands followed the navigation faithfully, and I heard Siri saying "you arrived at your destination."

To my satisfaction, I noted that I still have a few extra minutes, and the train station was right next to me... except that I was still on I-90 amid the river of cars. I have to allow that the app indeed took me to the point nearest to the address, possibly even to the train itself, as the rails run parallel to the highway. But as soon as I arrived, I also had to leave instantly as it would be the natural state of someone driving on a highway... [as I recall, some smart-heads rolled off recently at Apple due to the app's performance.]

After a frantic few minutes of reversing the course, I managed to find way to the other side of the fence. Panting and running toward the station, I heard and saw the train just leaving.

So, my spy mission failed. After the sprint, which I rarely have these days, I felt, you know, like the exhausted Gene Hackman in the film "French Connection", at the end of the exciting car chase, having been finally foxed out of the subway train, as he watches the villain calmly waving his hands and riding away...? So, could my day have ended at least as an earnest-cop-chasing-villain kind of day if not exactly a Bond day? Only if the day had allowed me doing all this wearing a decent trench coat like Hackman did. But the weather was damn warm today. It is not the gritty 'hood in NYC either, but a quaint Newtonville.

Ahhhhhh I feel ridiculous.... No I AM ridiculous!

I once laughed hard at the news of a hapless German guy who drove his Mercedes into the river as he just followed the GPS instructions. If you laugh at someone, it always comes back at you. And I promise myself I will never get annoyed with customers of Honk who inquire why the App says their car is in the middle of the pacific ocean...

Honk Icon

To continue on the evolution of Honk design, I will share how its icon design progressed. My experience tells me that it doesn't make too much sense to worry about the icon at too early a stage in the development of an App. Most likely, the app will go through many stages of drastic changes, add or drop features, and may even end up as something quite different from what was originally intended. If you spend too much effort into a pre-mature icon, and develop strong attachment to it, it will not only limit the way the app will evolve, but may end up as the wrong icon sitting on an otherwise excellent product. (Of course, the reverse may be true, I should add.)

It is obvious that the app icon should play a very critical role in attracting potential users' attention. Given how many times these icons imprint themselves on the phone user's mind everyday, a good icon design not only helps your sale but also mental well-being of general public. So it is a matter that needs be approached not casually.

It just happens that I am not a kind of person to whom the perfect icon materialize fully formed in the deep recess of the brain. On one hand, I was hoping that by the time the app is finished, at least a good idea may naturally come. On the other hand, I was jealously ogling at these apps which seem to have the perfect icons for what they do. My favorites include Bump, Classics (Of course!), Doodle Jump  and Twitter. They are not only visually attractive, but also capture the essence/spirit of the app in the most economical way. And I wanted that kind of icon for Honk.

Bluemeter merged icon57

If you read my previous post, you know about the original character of the app that I started with. So, for most of its development, the working icon was the one that I just lifted off my initial design of the meter. It is not very polished, but I thought it captures the playfulness of the flying superman, ship, etc in its cartoon cloud while conveying the practical functionality of the app through the blue and metallic head of the meter with its austere geometry. So well into early November of 2010 (Honk v1 was released in Jan 12, 2011), this was its icon in my mind. The casual way it looks was constantly influencing small coding decisions I make. I can almost say that most of the unprofessional touches in the app that remain were devised under its influence.

As the app matured in its tone and as it acquired more refined UI designs nearing its launch, we started to think seriously about the icon. I tried to nudge Daniel to come up with something on par with Google Voice or Twitter involving a semi-abstract depiction of a parking meter. Despite several iterations, however, I couldn't convince myself whether that was the right direction.

Icon test 24112010

We even had the candidate icon sit side by side with the competition in a mock up App Store rendition : While I feel that any of Daniel's versions at this stage was already superior to most of the icons in this list, we were not quite there. Frankly, I felt that the icon of Auto Park stood out among this crowd, and I decided that I will not be satisfied until our design tops it. One aspect that makes this game challenging and intriguing is that it involves the delicate balancing between the grab-attention and the durable-attraction factors. They are not necessarily compatible, and of course, the third axis is the constraint imposed on you : in our case the consistently ugly object that is the parking meter. Turning it into an semi-abstract form seems to alleviate the problem, but I felt that it was failing to meet the base need of eyes looking for an explicit eye candy. Maybe I was still looking for the fancifulness that I had started the project with. I briefly toyed with the idea of totally abandoning the constraint of having the meter image at all. But, by then, we were facing another crisis : we realized that all imaginable names containing parking, meter, alarm, etc had been taken up! [I may elaborate on this issue in a separate blog] So, removing the core image off its icon seemed too cruel to it.

Honk icon 512The Christmas came and passed us by. The world economy didn't collapse. But we were getting edgy. Through Phill, we managed to bring in David Lanham, a well known graphic artist, at this late stage. Speaking of infusion of fresh blood. Our icon problem was quickly resolved then on. Sure, conceptually, one may say that the final icon is conservative in that it depicts the main subject matter extremely loud and clear, hardly leaving any room for mental embellishment. I am no expert on the matter of graphics design, but what I feel is that once you saw David's design, you knew that it has reached the height, if that particular direction is where you want to go. I believe Honk wanted to go in that direction. About a month after its launch, Honk made it to be the App of the Week in the UK store, and David also made the feature artwork with a very satisfying result. Cheers to the pros!

Evolution of Honk Design

Honk was first conceived around 2008, when I got the new iPhone on my hand, and downloaded the first SDK for it. At that time, I had envisioned it to be just a simple alarm with a set of fanciful GUI elements. I came with a background in Cocoa/OpenGL development for my scientific research, but was new to the mobile app development, and it would offer a way to teach myself how to make an App. There was also an aesthetic impulse in choosing this topic: However hard you try, when you look at those ubiquitous parking meters, you cannot induce any trace of visual pleasure from their design. Ditto about most of the parking garage buildings. So, my primary objective would be to make an App that would help offset this yuk-feeling a driver starts his day with after having parked his car somewhere.

Over the course of two weeks that followed, I managed to finish its basic algorithms, but only to realize that the iPhone OS did not offer any way to allow alarms to work in the background. There was the notion of a remote push-notification service to arrive soon, and I briefly looked into what it was promising. An app such as Honk makes or breaks depending on its timely operation within minutes' (even seconds!) accuracy. It seemed, therefore, somewhat ridiculous (or very cool for some!) to have your parking alarm to travel across the continent and be sent back from a 3rd-party server which wouldn't  care less for what's at stake at your end.

IMG 0167So, I shelved it. At that stage, its GUI was not even started and I had only this sketch shown here made using an early iPhone finger painting app. During the following two years, I was busy with something else and iPark (my working title for the project at the time)  just sat inside a dead folder. In the mean time, many reckless souls apparently went ahead to realize the Great American Parking Meter App in spite of that fatal shortcoming:  there were quite a few that employed email messages, slightly more diligent ones resorted to the push-notifications. An app was even politely asking the user to keep it in the foreground until the alarm goes off. I am sure they all made a lot of money during those boom days.

Finally, as iOS acquired the (limited-)multitasking capability, it was now time to finish the project. By then, I had solidified the idea that it should also have an elegant and simple way to mark your parking spot. Personally, I have suffered as much annoyance forgetting the parking spot as from being caught by the meter officer too many times.

Given all those creative ways that garage owners use to mark their walls across the globe,  using pre-set dials is not the best way to go, even though it would be the easiest to implement. It occurred to me that a simple voice recording would meet all imaginable need while requiring a minimal user interaction. But I hate my voice. Furthermore, I find it awkward for an otherwise sane-looking person to whisper into the phone while staring at it. And what if you are hiding behind a car in a dark garage, a gangster on your tail, and desperately need to mark your spot silently in case you will manage to come back to your car? Having ruled out the picker (dials), voice recording , and typing for reasons legitimate and imagined, I figured that the hand-writing is the simplest and most versatile option. A decision that ate away several weeks of my development time eventually. But I am glad I made that choice. I am digressing. Back to the design of the main gui....

MeterWithBalloon

MeterWithSheep

MeterWithDuck

It is not very motivating to code without any visual feedback. So, early on, I did "programmer's design" of what ideal that was in my head. At this point, Honk was going to feature a randomly chosen-,  quirk but cute animation to zip across the sky whenever the user sets the meter. That looked pretty good. But many of the GUI elements in my design received criticism from my testers. Especially, the big round button at the bottom. Apparently, the metal sheen and the bevels hastily lifted off the Photoshop book were not quite up to standard...Despite these, the mechanics of its operation seemed good enough to indicate that something of commercial value was being made.

MeterDial

So, while I was polishing the algorithms to make the hand-writing work smoothly (this turned out to be much harder than I thought, largely due to the hardware limitations of iPhone 3Gs, and even 4G. Maybe a subject on its own for later. Had it not been for the iPad app, Penultimate, which was clearly showing that it can be done, I probably would have given up at some point.), I also contacted my son, Phill, asking for recommendation for a good designer to work with. Phill had gone through this kind of process quite successfully ("Classics for iPhone"). So far, I was being lazy in that the meter was using the vanilla slider object in an invisible mode, and dragging a rectangular view across another. If I were to hire a professional designer for the GUI, I thought, I should up the ante for myself too. So, I started the messy process of destroying and rebuilding the way the main dial works. Here is how it looked at that point. For a while, I just worked with skeletons and googled images. I focused more on the seamless working of the operations which involved threads, timers, queues, etc. Along the way, I learn that it is important to abandon an early effort and free yourself of burdens, especially if that was not your cup of tea to begin with. Enter Daniel Goffin, a young graphic designer that my son recommended. When we were starting, I still expected that Honk will keep the fanciful animations as its main GUI attraction. So, here is an example of what I initially communicated to Daniel to help him get in the right mood:

I recall it was Phill who had suggested in passing that we should use a blurred background instead of my original and brilliant conception of the flying ducks and sheep. Daniel also joined him. Even though I had a bit of trouble in giving up the rare chance to share my quirky sense of humor with the world, I was eventually persuaded. It pays to listen to what your son says. Nonetheless, I still believe it an opportunity lost when I look at the sketch that was to indicate an expiring alarm via the Snowy chasing off the parking meter officer... I so much wanted to have Honk help release the anger we all feel toward these impossible ladies! But the gain from listening to the veterans far outweighed this imagined loss: One thing I immediately noticed was that the graphics designers make their creations big and project more prominent presence. I am more of a muted, self-effacing school and tend to make all my buttons too small. But Daniel immediately established his newly designed meter square and centre in the main view of Honk. Naturally! I wouldn't object as long as the result looks gorgeous.

Settings rso

Settings screen

The image on the left shows my original design for the Settings view in which I used the vanilla buttons and the Picker elements, as well as the default font. On the right, we have Daniel's first design for the same, in which he replaced all aspects of the design elements down to the font to be used. As it turned out, the current iOS SDK does not allow even the simple switching of fonts for many of its parts, nor the color. To remain faithful to Daniel's aesthetics (which I also shared), I had to pay the price of making my own class of switch buttons as well as turning all text elements into separate view objects, which entailed many adverse side-effects...;-( To give myself some credit, I firmly believe in getting the small details right. So, I persevered and put in the necessary labor. As a result, Honk has some 220+ custom images, quite a bundle for a small utility app.

The only serious objection I had was the tone of the gray, which looked too dark and uniform. The meter itself and overall interface eventually became brighter. We also decided to minimize the space taken up by the row of buttons at the bottom in each view. To do so, we had to sacrifice the main navigation button in each view that allowed users to access directly other functionality of Honk. Instead, the final design uses the meter view as its hub, which works out fine for majority of users. Phill also forced me to spend good amount of time and effort to fix the logistics of views in their sliding up and down, teaching his physicist dad about how doors work in the non-Escheresque real-life world... ;-)

Meter

By the Thanksgiving day of 2010, Honk was gaining its final shape. We settled on the main meter design, and most of my fanciful ideas about animations, flying shark fins a la Jaws, barking dog sound as its main alarm, etc, had been filtered out by the pros. We also decided to save the nearby-feature for a later version, lest its designing process should further delay the launch. We were hoping for pre-Christmas launch, as we firmly believed that everybody in the world would want a parking meter app for their present. I also believed that only it would single- handedly save the world from the impending Depression.

Daniel and I got along very well: the strongest disagreement between us was about the color scheme of the meter dial. I am more for the cobalt-purple kind of guy (as shown in the figures below among the rejects), but he thought it should use the bright green and the orange, partly to be consistent with his design on the Settings view, but more for the traffic light metaphor he had in mind.

Once we decided to use blurred real life images as its background, it occurred to me that it would be fun if Honk alternates between a pair of images depending on whether the app is open during the day or the night time. Then, why not for every hour? I realized that finally the moment has arrived that will justify all the money spent to update my digital cameras!

One thing I noted was that when you take pictures, you tend to put most interesting thing in the middle. In our case, the meter obscures most of it, so a typical picture is not very useable. From thousands of photos I amassed over the years of my life, I managed to cull about 60 that would look OK. (By now, I acquired the strange tendency of avoiding the center of the scene when I take pictures.) The following are among those that didn't make the cut for one reason or another:

Hubble

Lenin

Applestore

The Hubble telescope picture which makes an awesome scene, I was not sure whether NASA would allow it, and there is no way to trick anybody into believing that I shot it. It was not a terrible loss though: the funny thing about our scheme of hourly background images that I hadn't realize until the very end was that nobody would feed the parking meter deep into the night when such image becomes relevant. So who cares but a detail-obsessed developer...? The one in the middle (taken from a street vendor in Paris) seemed too trying to be provocative with its cigarette ad, images of Lenin and McDonald sign (obscured by the meter). The third one, I was just afraid Apple may reject the app.

The following images that were also dear to me had to be ruled out:  With the parking meter replacing the guy being hugged, it made the woman look rather sick. The middle one is reserved just in case Mercedes might recognize Honk as an advertisement opportunity. (BTW, my title for the picture is "Bully".) The third one, the image of a beautiful girl I chanced upon in the Cloister museum in Manhattan, could not be used as I do not have her permission to use. (Just in case:  if you think you are this girl, and wouldn't mind helping a well-meaning, but can't pay indie developer, please contact.)

All images were blurred using Photoshop, but having devised an efficient image-blurring filter routine now, I am considering allowing user-taken images to substitute for the background in a future update. I am mindful, however, that it takes some effort to make images look attractive when there is this big phallic object in the middle. So the question is : do I really want it? It is one of the most often mentioned requests from users though....

By now, you may be thinking: Hell, it is all about superb GUI design that makes Honk what it is.... Well, given all the limitations of the platform and the scope of user expectation, a strong interface design is among the most critical components for sure. And we haven't touched on its icon design, another critical part, yet. However, having said that, I should also point out Honk has quite a few significant algorithmic innovations hidden behind its operation. But I cannot reveal them all under the watchful eyes of the mean competition in this small pond that is the Navigation section of the App Store these days. Speaking of mean competitors.... well, that's for only those of you who can stomach such things. I have more worthy subjects that I want to share. How about the icon design?

iStorm

iStormApps originated from iStorm and iChalk, two programs we had made years ago around when Gore dueling Bush was the hottest news. Storm here of course derived from brainstorming as the programs were meant to be real-time collaborative tool. And by we, I mean myself and my son Phill Ryu, who was in high school at the time. 

If you are curious about the concept behind iStorm/iChalk, you may look into the cheeky promo videos we made around that time. 

Somehow, the programs (and the concept) made some stir, among progressive educators in particular and yet, failed to take off big time. After all these years, I still muse about why. There are obvious steps we hadn't taken to promote, but the real point of my intrigue is the gap between the fascination the idea itself generated and the fact that people generally prefer less intense approach (such as emails and chats). A consolation would be that, years later, Google came up with a web-based take on the concept, executed it rather brilliantly, but only to fail and fold. (Google Wave)

The iStorm project was more like a "serious" hobby for myself and my son at the time, and we didn't have much marketing knowhow, although my son quickly moved on to develop one for one of his ventures. The US political turmoil at the time wore down everyone, and by the time we made RendezvousPong around 2003, I felt all my entrepreneural energy was drained out. In retrospect, one thing I am amused about is that the avatars I made for that little pong program as a tired political commentary managed to feature many of the big time players-to-be, including an obscure (well, at least to me!) senator named Obama and the senator-to-be, Al Franken. Only if I made such bets on little stocks I own....!

Over the recent few years, many events happened both personal and global. As a result, we all are people different from what we were in the last century, and here I am, working on a cute little App called Honk, to be offered at .99 cents! As a physicist who have fond memory of learning about the spacetime while learning the trade, I find it rather fitting that Honk is also about space and time in its way....
