Web Idea: P.I.S.S.

Do you, ever in your life, need to check the schedule of the next movie, train, ferry, or bus ? How many times do you need to check it, in a day ? Is that easy to “check” ?

I do it a lot and found it a very inconvenient task. You know, first you need to take out your PDA, notepad or wallet, find the schedule table (be it a spreadsheet file in your PDA, or a piece of paper). Then check your watch, tell the time and check against the schedule table. You’d probably need to check multiple times as well since you’d misread the schedule easily. Why can’t we have a simpler system ?

Let me introduce My Timetable Checker (version 1.0) :

  1. Dial a phone number, or surf to a web page, from your mobile phone / PDA
  2. Select the item (ferry / bus to certain destination, a movie’s name etc.) you want to check the next schedule
  3. The system will check the time of your mobile phone, perform a search , compare your phone’s time against the schedule table and then tell you (by replaying a voice record or just showing you the information) the next closest schedule.

Isn’t it simple ?

And My Timetable Checker (version 2.0) :

  1. As long as you preset where is your ferry pier or where is your preferred cinema etc.
  2. The system will check your location, based on the GPS system in your PDA, or cell stations around your mobile phone.
  3. The system will then warn you that you are not going to make it because you’re too far away from the ferry pier, bus terminal, cinema etc. and suggest other schedule.

Isn’t it even better ?

Who’s gonna do it ? Let me call this great system – Personal Information Search System (P.I.S.S.).

User Experience – Smart Elevator System

There are now many “Smart Elevator System” installed for new commercial buildings in town. Here’s how it works:

  • Let’s say you have 4 elevator cars in the building lobby;
  • Numeric pads are installed in common areas where elevator passengers wait. Passengers enter their destination floor on the touch screen.
  • The requests are processed, and a message is displayed informing users to ride one of the four cars.
  • And in the cars, there are no floor buttons (!).

In a way it works like magic – because it groups passengers to different cars to minimize travel time.

So, is it a good system ? I think it depends on who you are … I mean if you work in that building, this design is pretty good.

But what if you work for DHL, UPS or Fedex ? In other words, you are a courier and need to deliver packages to say 3/F, 11/F, 21/F etc. etc. ? There are no buttons in the elevator cars, you know šŸ˜Ž So, you have to press “3” in the lobby numeric pad, get into a car, go to that floor, deliver the package; then go back to lobby and press “11” in the numeric pad, get into yet another car. etc. etc. etc.

Lesson Learnt: It’s good for you, but may not be good for others.

User Experience – Supermarket

There are two supermarkets around my place and I visit there around twice a week. So, let’s see my grocery list (basically essential items for everyday’s living) … yogurt, juice, fruit, canned food / soup, ice-cream, meat, eggs, vegetables, bathroom tissues, beer, newspaper, magazines etc. etc.

So as a typical supermarket wanderer, I spend around 20, 30 minutes in the shop and seems to me the ideal “line up” of the goods in the aisles should be:

  • Non-frozen food and products (e.g. canned food / soup, eggs, bathroom tissues, beer, newspaper etc.)
  • Fresh items like meat, vegetables, fruit, juice
  • Lastly, frozen food like yogurt, ice-cream etc.

The idea is rather straight forward (at least to me) because I don’t want the ice-cream to melt, or yogurt get warm, or the fresh food get “un-freshed” in my 30 minutes shopping time.

But then, how these two supermarkets placed their products ?

  • From the entrance, you will first see ice-cream freezer … then, fruit, then vegetables, meat, yogurt …
  • In fact, the goods closest to the cashier are the bathroom tissues …

And further complaints … why can’t they put TV foods (i.e. chips, cheese balls šŸ˜Ž just next to the beer section ?!

Lesson Learnt: Oh yes, I reckon even a supermarket needs to improve the “Usability”.

User Experience – Octopus Card

Octopus card is one wildly popular “contactless” card being used in the city. What it does is rather simple, certain “value of money” is stored in the card such that you can go to subway, take a bus, or even buy something from convenient store … without cash.

It’s so popular that over 8 millions cards were produced and used. So far, I believe everyone in town has this Octopus card.

The usage scenario is like this …

  • You somehow need to pay something (goods, fare etc.) – e.g. in a bus, in a convenient store, entry gate of the subway etc.
  • You take out the card – by itself or if it is stored in your wallet, take out the wallet.
  • Wave the card or your wallet over a rectangular shape card reader (you know, it is “contactless”).
  • You will hear a “beep” or “dooo” sound to indicate the payment is done.
  • Then you can take away the stuff you just bought, or go into the bus to find a seat, or cross the gate to the subway platform etc.
  • If there is not enough money in the card, you will hear another “beep” or “dooo” sound and you need to find some service desks to “recharge” the card (of course, by paying some money).

Rather sleek, isn’t it. Now for my usability observations:

Case 1

Children use this card extensively to buy drinks, snacks and the card is recharged by their parents. In other words, they don’t need to touch any physical money bills, coins etc. (the real “money”). And you know what, they no longer has the concept of “more money”, “less money” or even “how to save money” !!

Case 2

Also related to children … other than not having the concept of money, many of them don’t even have the concept of the card – because the parents always keep the card inside the children’s small bag or wallet. I’ve seen a children complained to his parent that his little wallet was not working any more (to buy something), simply because his parent took away the card from his cute wallet !!

Case 3

This time it is about adults … in my apartment the main entrance is protected by some “advance” technology. That is, you don’t need to push any button to open the main entrance door, all you need is to wave your hand over a sensor. And the sensor will indicate the door is going to open with a “beep” sound.

And you know what, I saw a lady (probably a new tenant) take out her purse, wave over the sensor, waiting for the “beep” sound … and you know, it works as if the Octopus card opens the door for her …
