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.

Link: Precision Touch Screen

, , , ...


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.
