Blind Faith in Touchscreens and Apps

Golden Krishna’s Best Interface is No Interface is a criticism of the “slap an interface on it” mindset, the idea that if you put a touchscreen on anything, it must be an improvement over the old way of doing things.

 

He cites those self-checkout kiosks at many supermarkets as an example. Many stores in the US found that the incidence of shoplifting seemed to increase with the advent of self-checkout machines. Did people really start stealing once those machines came? Possible, of course. But it’s also possible that people are often confused – am I buying the supersized packet? Or the large one? If the buyer isn’t clear, guess which option he would be selecting…

 

The author’s point is not that the old systems and interfaces should not be changed. Rather, his ire is at the tendency to put a touchscreen’y “solution” to everything. Sometimes, an improvement can be without a screen. Take, he says, the problem of coming out of the supermarket with all those bags in both hands, and struggling to open the trunk. Would an app to open the trunk really help – how would you pull the phone out of your pocket with your hands full?!

 

Here's how Ford solved that problem. They put sensors to work instead. One set of sensors on the car detected if the owner was nearby. How? The car and the keys would exchange radio signals that could only work over a short range, i.e., when the two were too close to each other. Once they detected proximity, then the vehicle would use a kick on the bumper as the trigger to open the trunk. See how elegant that was? Yours legs were free, you didn’t need to fumble to get they keys (or your phone) out. It didn’t involve a touchscreen either.

 

Take the dishwasher. It has so many options:

“Appliance companies often feel the pressure to add a few more buttons and gizmos to get a few more bullet points that attract a few more sales without any advances in actual experience.”

Whirlpool’s solution:

“A button to end all buttons: A “Sensor Cycle”.”

The sensors measure the “temperature, soil level, and load size” and decides the right cycle. All without a touchscreen.

 

Having given many, many such instances, at the end, Krishna clarifies what his point is:

“(It) doesn’t mean the only outcome should be no interface, it means the best possible outcome is no interface.”

Aim for the best outcome, but yes, sometimes you have to settle. Such an approach would still yield better outcomes than the blind create-an-app approach or add-a-touchscreen approach would achieve. Touché.

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
