Improved tactile feedback with the Community SSU

The latest version of hildon-desktop features experimental support for improved tactile feedback. What this means for you is that if you enable this feature, you will "feel" app menus and dialogs appearing and disappearing, just like on some Symbian^3 devices. It's disabled by default, but you could give it a try and see if it improves your experience.

First of all, you have to install the tactile helper from Extras-Devel (Git repository here). Then, you need to edit /usr/share/hildon-desktop/transitions.ini with a text editor as root and set the value of tactilepopups to 1 (i.e. change "tactilepopups = 0" to "tactilepopups = 1"). Save the file, and the changes should be applied instantly (if you have the latest version of the CSSU installed). Yes, I know that this forks a new process every time a feedback is played, but this keeps the architecture open for experimentation and prototyping of new ideas. It also didn't noticeably hurt my N900's battery life when used for a few days.

One further improvement would be to add support for "tactile" into Hildon, so that it vibrates when you press a button, but it doesn't vibrate if you touch a non-sensitive area of the UI (because right now, it vibrates on every touch when configured to do so, and that's not really tactile feedback of UI elements - you can "feel" the screen anyway, and it doesn't matter if the device registered your touch if the touch turned out to fall into a spot where no action will be carried out). I'm not sure if Qt Mobility's Feedback API already supports controlling the N900's vibra motor, but if not, there would be another great improvement opportunity.

The tactile helper can be easily integrated in other apps, the source should be trivial to understand, and easy to utilize in third party applications. It also comes with an example ('tactile-demo.py') that you can have a look at for a more elaborate example :)

The Return Of Panucci (0.99.0 for Fremantle)

Since gPodder gained support for MAFW, and therefore resuming support for the built-in Maemo 5 Media Player, there was less of a reason for me to continue working on Panucci (though some users still prefer Panucci over the built-in Media player). Recently, Jens and Helmuth collaborated on bringing Bluetooth support back into the 0.9 branch in the Panucci thread on t.m.o.

Jens has also fixed some other issues and is now continuing development of Panucci, which is great :) I'll continue to package Panucci releases for Maemo 5, and review the commits and provide feedback, but won't be working on any features myself. Here's a teaser screenshot:

The new version, Panucci 0.99.0, has already been uploaded to Extras-Devel, and will be promoted to Extras-Testing soon. If you want to contribute, check out Panucci on GitHub - patches are gladly accepted!
