Drag Drop - a gesture design delema!

So I've run into an interesting interaction design problem. I've implemented some very basic list interface elements and initially supported the scrolling interaction via dwell regions. I'm unhappy with this for a number or reasons :

1) Dwell regions are not obvious to a user since there is no visual feedback to the user as to their presence. While I can provide feedback, there are times where I may choose not to do so (e.g. where the dwell region overlaps with the list).
2) Dwell regions when combined with other UI elements can hinder users interaction - e.g. if a user wishes to select an item that is within the dwell region and the dwell region initiates the scrolling behaviour causing the users selected item to move.
3) Interaction is very basic and I dont really want to implement any more support for these.

The obvious alternative to a dwell region though is drag and drop (or in the case of OS6Sense, pinch and unpinch) however since these are gestures, there's a possibility that the gestures will be interpreted as a command interaction.

But I want to be able to support pinch and unpinch...I think this is one that I will just have to try and see how it works out, but I think I have found a flaw in the interaction style.

I know I should move on and start a new blog but I'm keeping this my temporary home. New project, massive overkill in website creation. I've a simple project to put up a four page website which was already somewhat over specified in being hosted on AWS and S3. This isn't quite ridiculous enough though so I am using puppet to manage an EC2 instance (it will eventually need some server side work) and making it available in multiple regions. That would almost have been enough but I'm currently working on being able to provision an instance either in AWS or Rackspace because...well...Amazon might totally go down one day! Yes, its over-the-top but I needed something simple to help me climb up the devops and cloud learning curve. So off the bat - puppet installation. I've an older 10.04 Ubuntu virtual server which has been somewhat under-taxed so I've set that up as a puppet master. First lesson - always use the latest version from a tarball unless you have kept t

Prototype Hardware Rig

Its late here so I'm a brief post. As I've said, hardware wise there are a lot of options as to where to place the various components for a WGI and a few studies out there have looked at the various components in some depth (TODO refs). However an obvious constraint for this project is available resources (hardware, time, money etc) and when it comes to the act of physically assembling thing, and doing so quickly, for my first build it is almost a matter of just making the best out of things. Hence I present the rigging for O6Sense FG v0.01 which has been inspired by observing the trend towards the wearing of large closed-cup headphones and the opportunities this opens in having a "socially acceptable" wearable prototype. What is it? Its a pair of cheap headphones with the cups cut off and 2 Rode pop-shield mounts fitted into the rear wire loops. I cant help but feel some providence at work here since not only is the rear arm a snug fit the screw holes are the ex
