Google Wave

I love the idea of the Google "wave"; a move forward, away from traditional 1-to-1 email.

BUT, having been using Google Wave for a few days, there are a few things that jump out at me that could be improved.

Obviously it's a beta version or "preview"; some things will be fixed, others are just a question of changing habits and others may continue to confuse or encumber.
We will see.
  • To start with, I like the fact that you can minimise the different windows individually: it leaves a cleaner working space and is better for convenience and privacy. The only option you see in the centre of the page is "New wave"; remniniscent of the Google search page.


However, adding icons, labelling with editable keywords or colour-coding the different blocks for instant recognition would make it easier to find the one you're looking for.
As it is, I end up having to drop down each block in turn:

In fact Gmail suffers from the same problem - a ton of links and options that all look the same and require reading - a step back towards tidy looking but laborious controls and navigation.


  • Something I really don't like is that it adds my "avatar" to the top of each message; breaking the mental model I have of communicating with others. Currently it looks like the conversation is with 3 others, rather than between myself and 2 others: 3 in total.


  • At this point in time you cannot remove someone if you've added someone by accident, which is just encouraging mistakes (and frustration). However, it looks like sooner or later it will be possible.

  • It also assumes that we all will personalize our avatars as soon as we sign up, that the photo will be clearer enough to identify people easily, and also that you know what the people look like who you are communicating with.

Unfounded assumptions?

Maybe I'm unusual in not feeling the need to upload my photo.

People I know like to upload a picture of their car, cat, baby, something they identify as being representative of their personality, but not necessarily a passport photo of their face. The exception maybe in company use...

This means that the system of seeing who is in a coversation (or wave or whatever) is not very efficient: it requires holding the mouse over each non-photo to see who is included.

  • Also, I figured the difference between a wave and a ping was that the first was more akin to email and the latter to chat.
    I liked the idea of a quick ping. However, in reality they appear to be the same.


  • In the image above you can see a ping window over a wave window: both have the same formatting options and you can add other users. The ping window is just smaller than the wave window.

  • The search box seems to have been designed by programmers for programmers, the geek influence and design of this program is loud and clear(!). "Query", commands, and "Submit" not "Search"?!



  • Another disadvantage to me is that it's a separate account to my email account, which means another account to manage. Maybe with time they will get rid of gmail and integrate the accounts (I would be quite pleased to be honest).
What's cool about Google Wave?
  • It has the novelty factor of being able to see the other person typing in real time, - which makes it more interactive than email, though possibly counter-productive if you're watching other people type (slowly, clumsily or otherwise). --It could also lead to mistakes - people seeing things they're not supposed to while you gather your thoughts :o
  • Increased functionality: add gadgets e.g. maps, weather, yes/no event organiser, and I assume these gadgets will only increase in number.
  • The save search function could be useful and the way to find a recent wave (clicking on a contact) is nice.

  • But most importantly, adios to long forwarded emails messages and downloading mysterious attachments. Hoorah!

Which prototyping tool?

There are quite a number of (flashy) prototyping applications becoming available. So, while trying out the new ones, I thought I'd share my experiences.

For the sake of completeness, I'll be going from paper to the most expensive trial version I can get my hands on!

The prototyping tool candidate list so far:
  1. Paper
  2. PowerPoint
  3. Inkscape
  4. Visio
  5. Axure
  6. JustInMind Prototyper 2.6
  7. Adobe Fireworks
Things I'll be looking out for:
  1. Quick, easy and intuitive: Is it quick to install? Do you need to be a whizz kid, or can anyone pick this up and go without feeling lost and out of their depth? How much of a learning curve is there?
  2. Communication: Is the result an effective communication tool? Does it need to be supplemented with other documentation? Can it express interaction? - Anything that eliminates the need for extensive text descriptions is good to get projects moving.
  3. Flexibility: Low-fi, hi-fi, compatibility between operating systems, browsers, export to HTML, PDF etc.
  4. Complete: Does the application have everything necessary to get going? Are there stencils or (free) downloads available? Are there online tutorials to help advanced users get the most of the application and quickly shoot up the learning curve?
  5. Robust and error-resistant: Does it crash? Delete pages too keenly? Can I recover earlier versions?
  6. Ergonomically gentle: Too much drag and drop with the mouse is a killer and can lead to or aggravate Repetitive Strain Injury (RSI). Are there keyboard shortcuts? Is there a balance between drag, drop, click, type? Can other peripherals be used?
  7. Value for money: Are the most expensive applications worth their licence fees? Is there a free alternative?

So, let's get started. Today: PowerPoint.

1. PowerPoint
- PowerPoint?! For prototyping?!
- Yes, I had to use it once for a project, a requirement of the client!

Reasons for using PowerPoint for prototyping
  • You're new to prototyping and don't have a specialist application installed.
  • If your client is very Microsoft Office oriented (it happens), and wants to be able to modify the documents, it may be one of the few compatible formats available for client - consultant collaboration.
Who should or would use PowerPoint for prototyping
An expert user of PowerPoint for presentations new to prototyping.

If you know how to set up templates, make graphically attractive presentations, use animation and links, you won't lose too much time and the end result can be decent.

It can be quicker than trying to figure out Visio say, especially if you download these web controls and widget stencils (without them, I would probably not bother).

Pros and cons of prototyping in PowerPoint
Pros:
  • Being a visual format, it can be a good way to communicate users' needs.
  • You can copy-paste away - images and text.
  • Colours, animation, images and links can give it quite a bit of life and dynamism.
  • Just about everyone has some way of viewing a Powerpoint document, even if in Google Docs, Open Office...
  • It's fairly stable and can handle a lot of images (I've done 150+ page benchmarkings full of screen shots and not had any trouble with it crashing).
Cons:
  • Unless you're all using the same version of PowerPoint, things will inevitably move out of place.
  • It's not meant for prototyping, so there aren't a great deal of stencils available, although this number does seem to be growing.
  • It's not likely to have the slick, professional look other prototyping or graphic design tools can offer, especially if you're using anything prior to Office 2007.
  • If you have barely used Powerpoint, it's not going to be the best prototyping tool for you as it is not intuitive.
  • It's not a tool user interaction designers can use if they want their peers to take them seriously! It's not a cool kids' tool!

Which button gets me a latte?

2 giant red buttons, one orders a latte, the other nuclear war.

President - Hang it all. What's the point? It's a disaster.

All advisors - Stop!! stop! No! Don't! Wait!

Advisor 1 - That button launches all of our nuclear missiles.

President - Well then, which button gets me a latte?

Advisor 2 -Erm, that would be the other one sir.

President - What idiot designed this thing?

Advisor 3 -You did sir.

President - Fair enough.
Wilson, fire somebody!

Wilson - Yes sir, Mr President!

From the excellent Monsters vs Aliens, go see it!
