User Centered Design...HTC HD2- ringer shuts off when it's picked up!

, , , ...

It's a simple matter that just about any modern smartphone can do, but it's the fit & finish that make a great user centered experience.

The HTC HD2 (which I'm impressed with) uses its accelerometer to silence the ringer when the user picks up the device. Great for those that fumble around in their purse or computer bag because they forgot to switch to vibrate (use Locale on the Android platform!)

Physical gesture based dialing

, , , ...

Way back in 2002, I found a little web browser called Opera that had this feature that just blew me out of the water...mouse gestures.

Since I've become to rely on them for browsing, I'm also looking at all the other plugins and extensions that extend this functionality to other pieces of software and interfaces.

Phones now have accelerometers that detect 3D movement, so it seems natural to use movement and gestures to perform functions on the phone.

I've just viewed the video for this phonepoint pen project by Duke students that uses the movement to translate and do OCR on captured movement to text. I think this is interesting, but not very practical. Instead, I'd like to capture the movement and translate them directly to commands. Keeping with the Opera browser mindset, I'm picturing a handful of easy to perform gestures that are one or two linear movements that can be turned into key phone functionality. Apple is tapping into this idea, they just announced "voice control" and they have a handful of physical based gestures- but they are just on the tip of the iceberg: they have "shake to undo" or "shake to refresh" functionality, but this can be extended...

  • Speed Dialing a phone number (one gesture for each favorite contact)
  • Launching a browser
  • Initiate a desktop-to-mobile sync/handshake
  • Move data from phone to desktop
  • Copy, paste, delete, add...
  • Refreshing the current view (existing)
  • Shake to undo (exsiting)
  • launch maps and use current location (ideal for auto based "where am I?" queries)


But mainly things you'd be likely to in an automobile or need to get at frequently and quickly...what I like about gestures, is that you can do them without paying attention to the interface- there's no mental/cognitive cycles spent doing mundane interface manipulation. You're using muscle memory. Like my browser mouse gestures, I can still be in the middle of finishing up scanning the text of the page and close the page without any movement to the "x" button (or any real thought). at the sake of going off on my mouse gesture tangent, I'll leave it at "if you get it, you get it, if not, you don't" and just press on: On the mobile device, this opportunity is greater. I think this is easier to use than even physical speed dial buttons since you'll have to orient your hand to the phone and find the right button. With a physical gesture, you can find a single "activate" button (which would be consistent for all gestures of course) and then just let your muscle memory do the flailing!

I can think of some contexts & settings where voice controlling would be more appropriate, and I can certainly think of times when it would be more discrete to swipe your phone quietly through the air.

Anyway, I'm almost certain that someone already has some form of this out that goes beyond the "shake to X" functionality, so I suppose I should just wait patiently for someone to point it out in the comments. I've seen the speed dialer app that lets you make a gesture on the screen of the iPhone to dial someone, but that has none of the advantages of abstracted UI that I mentioned.

"Eyes free" dialing on a touchscreen

, , , ...

Google Project Eyes-Free

One of the problems with all the touchscreens rolling out these days is that there is no tactile feedback when you are running your fingers over the screen, you take that and mix it in with the fact that the screen is completely context dependent and you get a device that's almost completely unusable without looking at the screen.

To address this, here's a concept that lets you use "relative positioning" for dialing a number using finger gestures that is great for accessibility, but also for all of us that would like to access things quickly and easily without looking at the screen. I fell in love with gestures when I first met Opera back in 2002, and I'm always interested in how/when they are implemented.

Project Eyes-Free aims to enable fluent eyes-free use of mobile devices running Android. Target uses range from eyes-busy environments like driving, to use by people who are unwilling or unable to look at the visual display. You can get a high-level overview of more potential use cases for Eyes-Free from this recent New York Times article. As described in the article, we are releasing components from project Eyes-Free as they become ready for end-user deployment.


Great video/interview on Palm Pre

I'll link this up because I'm excited about the Palm Pre's focus on user experience and data conservation. Plus, I think the interviewed Roger McNamee is pretty reasonable when surveying the mobile landscape...

Interview RE Palm Pre

2009- Location Based Services will come of age

, , , ...

I talked last year about my desire for a location aware task list,and having phone settings be context aware(although that link was not GPS based), so I was excited at the potential applications for Locale on the Android platform.


Locale allows you to create Situations, which specify Conditions under which your Settings should change. For example, your At Work situation might notice when your location condition is 1600 Amphitheatre Parkway, and triggers your ringer volume setting to vibrate. Locale is an innovative way to simplify your life.



This is really getting into what I think technology should be doing for us- context/location/situational awareness that adds value. I'm excited to see what location based services will come out now that mobile application development is reaching the masses, and mobile devices are growing to embrace.

I hope to keep an eye out on location based services here on this site, so if you run across some news, feel free to post it!

Integrated Bluetooth headset: convergence where it makes sense

, , , ...

Someone finally implemented an idea I mentioned here, integrating a Bluetooth headset directly into the phone!

Interesting concept, there's only a few details from gizmodo. The usability aspects are interesting- you charge only one device, you can choose to use it or not, but it's always available (not in your car when you want it elsewhere), you don't have to carry the headset around with you. I think it makes sense to combine phone with handset.

Modular Phone UI

, , ,

http://crave.cnet.co.uk/mobiles/0,39029453,49295452,00.htm

Here's the Modu phone concept. It's an interesting idea of having a core unit that might plug into other UIs that share some core functions and information (like an address book). The article shows a music player, phone and car stereo "plug-ins"

Of course, this is nothing new- we're already pretty darn close to this already. My iPod- I dock it at my computer at home, I (essentially) dock it into my auto's stereo system, I set it up with portable speakers, and dock it at work. It's already a device that works in harmony (sometimes) with all these other devices and interfaces, but with the added bonus of being it's own self contained UI. It's making these modules more meaningful such that the user experience is married to design of the devices that's missing- that's what this concept is looking to address.

I'd like something in the middle- ideally, I'd like an...well, let's say iPhone... that I could slide into a small lightweight keyboard, I want to be able to dock it *into* my computer at home, have it marry up into my car stereo; in which case I'd like to be able to just slide it in like an old cassette tape.

dantesoft, who clearly was concerned about the lack of posting as of late, sends in yet another link from the Technology Review

Precision Pointing with Fat Fingers

Interesting approach. It's nice to have a toolbox of techiniques to use as we get more mobile devices and interesting interfaces.

Thanks again Dantesoft!

Widgets on the go

, ,


Apple put widgets on the iPhone, and now it seems Alltel is doing it as well. They're calling it "CellTop" (See the Frog Design Study), and widgets are called "cells"

I don't think this contrasts to the "whole web in your hand" idea that Opera is doing with Mini and Mobile. In fact, I'm in favor of the the Open Standards, I'm against .mobi, and nobody should have to code so many different versions of their site. But, that doesn't mean widgets and rich applications can't add value. When it gets down to it, I just want to have the movie times, wikipedia, IMDB, weather,...information quickly at my fingertips. Granted we now have a lot of ways to get most of that information... google gets it quickest now, either through just a search or even the Google SMS, but Rochester City Bus Lines is another issue.

So I'll just sit quietly and wait for Opera Mobile and/or Mini to also support widgets. How about it Opera?

Send...Don't Save

, , , ...

One of the hallmarks of today's generation of mobile devices is a built in camera. I love the convenience of having it around, but why do we need it? Rather, what do we really do with it? I'm sure you bought it thinking that you now have the ability to:
  • Snap pictures of your run in with Tom Hanks at that Los Angeles cafe
  • Capture the "fender-bender" for the purposes of having them be admissible into a court of law
  • Replace your Digital SLR for capturing the sun setting over the Pyramids of Giza (insert you correct spelling)
  • Have an image to go along with every person in your address book.
  • You see something funny/interesting/cool you want to blog/share/save


According to my rigorous scientific studies (ie- completely made-up) 98.56% of the usage of your camera is for the last bullet there. What's got me writing today is that even from that bogus number, a large percentage of those things I take a picture of are not anything i want to have around for any extended period of time. If it *is* something I want to keep around, I would have already emailed/sent it off to a place where I could more easily share/retrieve it.

So what are we left with? In my case a phone full of garbage that needs to be cleaned up in regular intervals. Why isn't there a "Send but don't save" option? Does your phone have this? Every phone I've seen lets you do the following:
  • Save
  • Delete
  • Send

..mine also offers quick menu access to take another picture, or to set as callerID/Wallpaper.

I never see a "send and delete" or an automatic image cleanup, which is most often what I'd like to see happen. I'd like that UI above, but see a distinction between "save" and what I'll call a "work with" or "working image." (A better term would be appreciated...) This working image is something you are going to send, or crop or set or share with someone via MMS or email.. something that you don't want to "save" onto your phone in the traditional desktop sense. Speaking of the desktop, it's not immune to this either- working with screen captures and file manipulations and image downloads, you often end up with a littered file system that takes a strict "system" to keep the craft from the clutter. This system is most often just the user's behavior that compensates/adjusts for the lacking software. For example, in my case: "I store all my 'temp' files on the desktop- that forces me to deal with it eventually..."


Some picture I've already used, but is still on my phone.
BTW-Opera can we get a *real* image caption thing here?



In the case of the phone, I'd like the same "clean-up" rules applied to images as are applied to messages (MMS/Emails/etc..). All the handsets I've had offer a clean up after "X" days of messages. Applied to images, this would clean out all old *unsaved* images...of course, if you do happen to run into Tom Hanks and you want to show that around to everyone you meet, you'd just choose to save the image and it would be spared. Designed *this* way, the phone interface would be more in tune with my usage.

It seems silly to me to treat images differently than messages. Sure we tend to get much more of the text variety (so "X" wouldn't be the same for both), but the same circumstances apply. Some are important which we know to save or flag or move.. but images are all assumed to priceless artifacts just waiting to be submitted to the Louvre, when in reality it's a funny misspelled sign you saw on the way to work three weeks ago that you already blogged about.
