Supporting Net Neutrality


Every human being should be treated equal, so should be every byte of information on the internet. That’s why Net Neutrality is important to us. But now it is endangered by FCC’s new proposal of rolling back net neutrality rules. If internet service providers (ISPs) can prioritize data from certain website, and slow down the data transition from others, these ISPs might able to profit by providing high speed internet services to some big websites such as Amazon, Google or Netflix. But at what cost?

Let ISPs blackmailing every transmission on the internet will no doubt harm the weakest, i.e. startups, small business, personal website and p2p connections. The rising bill of websites trying to maintain their access speed will eventually paid by the public. Furthermore, high volume internet service like HD video, livestreaming and video call are using bandwidth because they are popular. Removing the regulation on net neutrality is as worse as removing police patrol on Interstate highways.

Net Neutrality is a complicated topic involving laws, government agencies and mega companies. I am personally against the new proposition of roll back net neutrality by FCC. I strongly suggest everyone interested keep reading:

Fast UX problems found in eBay


1. Consistency of Navbar

    The “Hi #username” dropdown menu at the top left navbar is usually put at top right by almost every other site, lack of external consistency.
    The “Hi, #username” has an arrow indicating it has submenu, whereas the “My eBay” doesn’t.
    The hyperlinks are blue on the left but gray on the right.
    “My eBay” and “My eBay – Summary” goes to the same page, “Hi #username — My Collections” and “My eBay — My Collections” goes to the same page. Why not just combine them!

2. Consistency of "My eBay"

The “My eBay” is supposed to be the center for user to track Sell/Buy status, messages and account information. But its four tabs seems to come from four separated websites. Don't you click? Dear designers?

    The “Activity” tab looks best, with up-to-date font, coloring and layout. The active menu bar item is highlighted with the arrow shape which gives people clear visual indication.
    The “Messages” tab suddenly has a header ad inserted. Each links, are blue here. The arrow indicator is gone.
    The “Account” tab looks like ten years old. Breadcrumbs navigation is back at top. The tabs now have rounded corners and shadow effect, just like old days. I don't understand why Arial, not Helvetica is used on “My eBay” only in this tab, and why the colon mark is gone!
    The “Application” tab seems a little shy, so it doesn’t show up in the first two screenshots. Ad is gone, Helvetica is back. Breadcrumbs tells you that you are in “My eBay Beta” now.

3. User freedom of Changing username

Don't go nowhere once you decided to change your username. The username editing page doesn’t have a cancel button is not a big deal in other websites. But if eBay says: “You can only change your username once every 30 days”. It’s better to give people a way out for reconsideration rather than force them to use the Back button of their browser.


4. Confusing words/Speak user’s language

While eBay did very well on explaining special terms in many other pages, there is no description about what is a Telephone PIN. I don’t think PIN means number, but the button says: “Submit & Update Telephone No.”


5. Confusing words

“Call us” vs. “Call me”? They look identical expect the picture and the amount of people being called. People might figure out later about the direction difference. But why not change the “Call me” to “We call you” or “Get a call”.


The overall in-site consistency on page layout, design language and wording are disappointing on eBay. It feels like Frankenstein just put the site together using parts found in random places of the internet. These problems can still be found by March 20, 2017. I hope eBay can fix them ASAP. And I will be happy to see this article become an archive by then.


If hundreds of people made this mistake, there may be a reason (and a solution) for it


The “Can Opener”

The 11 foot 8 Bridge is a railroad overpass in Durham, North Carolina, USA. The 11 feet 8 inches clearance makes it 2 feet lower than average height of semi-truck trailer. Although it’s not the lowest bridge in the States, a YouTuber named Jürgen Henn started posting truck crash video of this bridge recorded from his webcam from 2008 and made this bridge famous among the internet. Based on the Wikipedia discerption, the bridge can’t be raised since rising a railroad bridge cost too much, and the street can’t be lowered because a sewer runs closely under it. This awkward situation leads to thousands of trucks lost their roofs, and gives this bridge a nickname: “The Can Opener”.

Luckily, the city installed a new warning system to notify any trucks taller than 11’8” with a sign of “Overheight Must Turn” and extra red light time. It indeed lower the rate of trucks hitting the H-beam steel protecting the bridge, but every now and then there are new victims coming. Just like this following video shows.

Let’s stop questioning the effeteness of government works, the story of this bridge makes a wonderful thought exercise of fixing real-life usability problem. The bridge is not a software program, but like many computer system, some UX problems are currently impossible to find a total cure due to many limitations. How do you temporarily alter the design to stop frustrating fresh users (or chop more roofs)?


Problem Defined

  • The clearance of the bridge is not the only reason causing this chaos, if you observe those crash carefully from the video. Here are some others.
  • Many vehicles hit the H-beam are rental trucks and RVs. These drivers don't know the terrain as well as local drivers.
  • The intersection by the side is very close to the bridge that turning vehicles might don’t have reaction time to read the sign before they try to stop.
  • Unlike some other tunnels, this overpass looks wide and spacious, which doesn’t raise the alarm for drivers to be careful.
  • If every bridge has yellow colored height warning, chances are human brains will just ignore the same warning there.
  • Error Prevention system

    Blaming careless truck driver like many comments under the video is easy, but won’t help solving the problem until every US truck driver had heard of this bridge. The bridge won’t be relocated, the height is fixed, the intersection will remain, what can be done?

      Break the common state, Bring Back the Self-awareness
      Convey the Message

    The human error usually appears when humans think they are safe, consistent, and everything is in normal condition. If I am a rental truck driver, this bridge looks normal to me since every bridge has yellow height warning signs and my head is far away from hitting the concrete wall. To fundamentally convey the warning message, we need an error prevention system that looks totally different from other bridge, while stays as an organic part of the environment.

    Solutions

    The “Overheight Must Turn” sign is contributing in crash prevention, but a better soliton is always possible. The core concept for preventing this human error is to convey the prioritize warning information, and makes it stands out from all other white noise info human brain takes consistently. The best way to do so is to make the warning looks different than the environment.

    Solution1

    Solution 1

    Billboards on the road sometimes attracts more eyes than warning signs. When sensors find an upcoming over height vehicle, they trigger a signal to light up the warning billboard. Speak Human Language rather than icy Traffic Warning Language will convey the message better, since there is enough space to put the image with text. An advertisement-style picture with off-roofed truck will instantly bring people’ awareness when they are driving similar trucks or RVs.

    We should also put shock sensor on the H-bar, so each crush will be added up to the counter of a microcontroller. This smart system can also gather information from other sources such like Traffic Control and surveillance cameras. Numbers on seven-segment-display will make the billboard more lifelike.

    Solution 2

    Using live camera feed for a digital billboard will bring more attention. Every person has self-awareness, especially in front of live cameras. That's why some people feel awkward when they walk through a surveillance TV and find themselves in it. A research found that self-image attracts more people on the road and brings more interaction. Live video with people's own car on it might the same effect. Drivers will think twice before entering the bridge when self-awareness is raised.
