Confession: I’m A Touchscreen Snob

Continental Touchscreen

I’m a touchscreen snob, and I bet you are too. I bet every human being is. We get upset when things don’t react as expected and we get frustrated when things aren’t instant. Statistically this page loads on average under 2 seconds and it’s likely still too long for you. It’s not just touch screens. For example, 100 ms increase in load time of Amazon.com decreased sales by 1%. We’re an impatient species.

I took the above photo on a 757-200 equipped with touch screens on the back of every seat. I remember the days with only a handful of TV’s, or that big projector thing up front on planes, so I appreciate that a choice of entertainment is an upgrade. Lets take a look at it’s sins as it makes a great example:

Resistive Touchscreen

I’m virtually certain based on it’s poor performance it’s a resistive touchscreen. Unresponsive, and it requires a lot of pressure which the person in the seat in front of you enjoys for 8 hours. Resistive touchscreens are much more cost effective, though I wonder that difference is splitting hairs on a $65-80 million aircraft given there are only ~200 seats and the displays are relatively small.

There was a time when nobody would notice, but even a Droid v1’s touch screen is more responsive, and that phone is extensively laggy.

Poor Contrast

Part of this is likely because of the substrate used for resistive touchscreens, but the poor contrast is obviously an issue. Color reproduction is bad, but that’s not a deal killer, it’s a nitpick. Contrast is critical especially on a vehicle where lighting varies from dark to virtually unfiltered sunlight glaring on the display. Contrast controls are minimally helpful here.

Laggy

I suspect these are units are just terminals, so the performance can sometimes lag. It’s forgivable and likely will not be an issue in future generations. Thanks to the mobile revolution low powered ARM chips can be found everywhere. The need for these things to be dumb to save space and power is drawing to a close.

Sound

I’ve yet to figure out why airlines can’t manage to get rid of the noise in the lines. Sure when you use the $0.25 headsets they hand out you can’t tell the difference. But when you use your own higher quality headset you sure can. Given a cheap mp3 player can manage it, I wonder why this is so difficult. Weight?

My second gripe about sound is the volume differences. The movie is set to a comfortable level. If the crew takes over to show a video of your destination or a safety video, it’s uncomfortably loud. If the captain speaks, it’s painful. This is more than a nuisance, this is actually a safety issue.

One thought on “Confession: I’m A Touchscreen Snob

  1. I really wonder why they can’t give each passenger an iPad (especially on long haul flights). Scale effect means it’s 100% sure an iPad would be cheaper than this equipment.
    An iPad case with a Kensington lock is not expensive at all, see http://www.amazon.com/iPad-Loc.....B004G6RNWM
    I just hope one smart company will understand it, and next everybody will have to do it. Passenger *will* accept to pay a few dozen bucks more for their long haul flight if the company makes it visible they will have that on it.
