    • “The accelerometer knows in which direction the phone has moved in three dimensions – but it does not know how the phone has rotated around its own axis,” says Nick Black, co-founder of San Francisco-based location-aware mapping platform maker Cloudmade.
    • “And the compass knows which way the device is pointing – but only along one plane. It can’t tell if the device is pointing upwards or downwards,” he adds.
    • But it’s perhaps augmented reality (AR) apps that will see the greatest benefit, says Black. In AR, iPhone-generated imagery is pasted over the real worldMovie Camera – rather like virtual graffiti. The phone’s GPS and compass help to establish the phone’s position and two-dimensional orientation, so that when phone’s camera is pointed towards a restaurant, for instance, the phone’s screen might display reviews superimposed over the video feed.

      But without the additional 3D orientation information that the gyroscope will provide, any virtual text or images will drift relative to the video as the phone is tilted, says Black. “More accurate sensors could make the experience more enjoyable.”

      Marcus Thielking from mapping app maker Skobbler agrees. “I see this as tremendous benefit for pedestrian navigation, bike navigation and any map-based app which you use holding a device like the iPhone 4 in your hands,” he says.

    • Image tracking for AR requires that visual data be analyzed 30 times per second, and using a high-resolution image could slow down this process and make the tracking less accurate, or lag-ridden. To avoid this, Misslinger says the use of the full resolution will likely be on a case-to-case basis. For closer experiences, a lower resolution image should suffice, but for tracking markers that are larger or father away, the full power of the camera may be required.
    • As Steve Jobs demonstrated, the gyroscope will allow the device to interpret its specific location as it relates to gravity – as the person turns in 3D space, the phone will recognize this motion based on sensed velocity. Most people immediately thought of augmented reality when this feature was introduced, and Misslinger says this is an obvious tool that AR developers will quickly adopt.

    • Sounds perfectly reasonable and I hope they can pull it off. Google hasn’t shown the UI design sensitivity necessary to compete with the iPhone UI, but they are determined and iterate quickly, so they can probably get to a point where their UI will be better than what handset manufacturers can come up with.

      Openness is great, but being open without setting a high standard is not good in the long run.

    • Wanting choice and keeping companies from customizing their product to differentiate them seem to be goals that are at odds with each other.

      However, I’ve used a number of android based phones and I still find the Nexus One’s interface to be the best and cleanest.

    • I would like to know more about uses of the Android Cloud to Device Messaging API
      that can be implemented in the simplest ways for mobile phone users,
      not to require downloads or installs.

      As an example – could a website about mountain travel
      accept people to login with a Google account (a bit like OpenId login)
      and send weather warnings in the notification bar of an Android phone using that Google account,
      with the notifications sent by the website’s server
      via Android C2DM with no need of a dedicated application downloaded and installed on the phone?
      Could the instruction to display a very short info message in the phone notification bar,
      plus the (very short) message itself be crammed in the 1024 bytes length of the C2DM message,
      or the meta data would need all the space, and a Market-style application be necessary?
      Could the Android C2DM frameset be modified in future, for a larger than
      1024 bytes message size,
      to allow for a short info message to be sent directly via the C2DM to be displayed
      in a phone notification bar?

      I know that the push-sync feature of Android C2DM needs Android 2.2, and Android 2.2 is not available yet for general use, but I hope it will be available soon.

      Sorry if this is more a discussion than a question.

    • Switching to Android

      Many developers don’t want to wait, and say they can’t take
      the risk of developing for a yet-to-be-perfected platform. Even
      long-time Nokia software authors are looking elsewhere.

      Take Alan Masarek, chief executive officer of Quickoffice
      Inc.
      in Plano, Texas. Nokia helped his 150-person company become
      one of the biggest independent mobile apps developers with its
      stripped-down word processor and spreadsheet running on more
      than 240 million mobile devices worldwide.

      About 1 1/2 years ago Masarek, whose software is preloaded
      on all Nokia Symbian devices, began working on Android phones.

      “That in hindsight has proven to be a good move,” he
      said. “The numbers on Android are very ascendant right now.
      We’re on all these devices that just started shipping in
      meaningful volumes the last two quarters.”

      Android-based smartphones threaten to top the iPhone in
      2013 in market share, according to Framingham, Massachusetts-
      based IDC. Shipments of Android devices may reach 68 million
      that year, making it the second-most popular operating system
      after Symbian, according to IDC.

      For Quickoffice, Apple and Android now each account for
      about 30 percent of shipments against 40 percent on Symbian.

    • “Development on Symbian has historically been difficult
      and Google and Apple leapfrogged Nokia in terms of developer
      friendliness in the past two years,” said Phil Libin, chief
      executive officer of Mountain View, Calif.-based Evernote Corp.
      “There’s no comparison.”

      His 30-person company’s main product is a note-taking
      application that runs on desktop computers, iPhone, Android,
      BlackBerry, Palm’s WebOS and Microsoft’s Windows Mobile — all
      except Nokia’s Symbian.
