Seamless interfaces and emoji injection


One recent trend in UI design is to build seamless interfaces. The underlying idea is pretty reasonable, get rid of useless clutter to get cleaner, more readable interfaces. This typically means removing a lot of lines, boxes, shadows and other highlights. In short, cut out the structure, leave the content.

Like any good idea, taken to extremes, the result is horrible, instead of a UI that is clear if a bit clunky, you end up with the UI equivalent of modern art, vaguely elegant, but very difficult to understand. The other problem is that by removing the boundaries between pieces of information, you remove the context they are valid in, which opens up a lot of way to confuse the users.

Consider this table to display that trust status of users in a system. The data is presented in a very structured way, nearly a database dump, really, with a little bit of decoration.

The same information made seamless would look like this, boxes and column headers removed, the information distilled to simple icon (here we can even use an emoji character). The interface is much more compact, and easier to localise to boot, better in each and every way.

Problems arise if the users can change their names: bad guy can now try to put out of context information into his name, for instance here he can inject an emoji character into his name. Bad guy’s lock icon is part of his name (Unicode character x1F512), because there are no boundaries, no context it is difficult to figure out which information came from where.

Name Secure
Good Guy yes
Bad Guy 🔒 no

Such an attack is less efficient in an old style UI, because the context shows us what information is what explicitly, instead of making that information implicit. We end up with the usual tradeoff: implicit informations is more natural, more fluid, but also more error prone and more difficult to check.

Aikidō Weapon Bag

After some time of usage

My work is not exactly manual, so once in a while, I like to do things with my hands. I have a weapon bag of the brand Budo Nord for my Aikidō Jō and my Bōkken, whose bottom go pierced. This seems to be recurring problem with weapon bags, as the two wooden sticks eventually pierce the fabric. The fact that in my case, the bottom was just built from relatively soft fake leather did not help.

I had an old leather wallet that I had bought in Japan, the zipper was broken after five years of usage, but the leather was still relatively good, so I stripped away the fake leather from the bag, cut the wallet into a reasonably regular piece of leather and sewed that piece unto the bottom of the bag.

Now this sounds very professional, but my sewing sucks, in particular with leather. I had a strong needle, but I though I still had my sailmaker’s palm from my sailing days, but I seem to have lost it, so I ended up using a thimble. The result does not look really nice when you look closely, but it was sturdy enough to survive a hectic train trip.

Aikidō – My Spiritual Journey

Gozo Shioda was among the earliest students of Morihei Ueshiba, the founder of Aikidō. He trained with o-Sensei before the war, and founded his own dōjō, Yoshinkan, in 1955. This book gives an overview of Shioda’s perception of aikidō, and what he learnt from Ueshiba.

While there was always a mystical component to aikidō, and the book’s title suggest something mystical, Shioda appears as a very pragmatic person, explaining his experiences, how they relate to the various aspects of aikidō, and the teachings of o-sensei. The book reminded me a lot of the Book of Five Rings, with its no nonsense approach to Būdo, and the ideas are pretty consistent: the plan of no-plan, de-emphasising techniques and an insisting on the importance of a good posture. The book also has five chapters.

Besides the principle of Aikidō, the book, through its anecdotes, gives a glimpse into the adventures of Morihei Ueshiba in Mongolia, which sound like something you could do an adventure movie out, but also the rough relationship between dōjō before the war, the scuffles with the yakusa, it felt like a grimmer version of Ranma ½.

Yoshinkan is known as the aikidō that is taught to the japanese cops, and reading this book, you understand why, this is the aikidō that branched off when o-sensei was young, the practice rough, and japan very disorganised. There is certainly a huge effort to change a mystical experience into something structured that can be taught, even while admitting that techniques are not the real thing.

While certain ideas, like the fact that aikidō is 70% atemi would probably make my teachers cringe, nothing written in the book feels inconsistent with the practice I have done. Shioda admits that he really understood aikidō when he was in a fight in China, and wonder how people living in less troubled times will get that experience, but I felt no regret, no nostalgia, just a teacher pondering on some fact and how to teach best in those circumstances.

One section I found very interesting is Shioda explaining why there is no competition, as this is one thing that sets aikidō apart from other martial arts, like Judō or Karate. He makes a pretty good point that a sport cannot be a martial art, as competition will always impose rules that warp the martial idea. I also found interesting the fact he stated there would be not static principles that would be repeated often, something I experienced during my short practice of Shōlin-ji kempō.

The text is pretty short, 200 pages including ≈15 pages of afterword by Gozo Shioda’s son, Yasuhisa, which I found moderately interesting. One thing I must say is that the paper and the printing are gorgeous, making it a pleasure to read.

All in all I found this to be an excellent book about aikidō, which gives a pretty sharp picture of the characters and the idea that underlines this martial art, certainly a much more concrete narrative than what I read in the Shambhala Guide to Aikidō or the Wikipedia. I really recommend this book if you are interested in aikidō, in particular the non mystical parts, and I think it is a worthy read, even if you are training in other branch of aikidō, like I do.
