3D pointing and drawing

leave a comment »

This is a prototype for pointing and drawing in a 3D space. I think this could be helpful for annotating and marking 3D body scans.

I used a simple color tracker to detect the pink top of the pen. 1 webcam is tracking x and y position, the 2. webcam is tracking the z position of the pink-pen-top. But you could also imagine this working with tracking a finger or even multiple fingers.

I think it is a very interesting to make these 3D interface explorations… but how reasonable are they for the radiologists work? At this stage of the 3D concepts I still see a lot of problems.

mid-semester review

leave a comment »

We had our mid-semester review yesterday with all my fellow students, Matt from Tellart, Mattias and Mikael. For my presentation I prepared an overview of my research and also sorted my concepts from the ideation phase. I sorted and categorized 3 main concepts for my mid-semester review – the plan is to choose one of these in the end of this week and start the “design phase”.

This picture is an index of things I’ve done for this project so far:


I got some interesting feedback during and after my presentation. Read on to see the feedback…

Interfacing with a healthcare network #2

leave a comment »

I’ve worked on my initial concept sketches for interfacing with a healthcare network and combined the 4 different concepts in one more complex concept. I did some flowcharts and mind maps to get an overview of my ideas.

This chart shows the basic workflow of a radiologists (Homescreen with schedule —-> Case viewing and Image analyzing —-> Report). I connected all the information from the network that could be helpful in each of the 3 steps. My main ideas for this still circle around crowd- and data sourcing, social networks, emotional connections and telecommunications.

Based on this and my initial concept sketches I’ve created some simple wireframes of an interface (view the pdf here).

Link/Inspiration collection

with one comment

I stumbled upon some interesting projects and interesting links since I closed my research phase (thanks to everyone who pointed me to some of these!). Approaching the end of the Ideation phase I thought it might be time to go through all of these links and highlight the most interesting here.

Dicom image viewers have the ability to show scanned images with different filters applied. It helps in situations where the radiologist is interested in only some of the body parts. For example there could be a filter that shows only the bones and another filter that shows only the blood vessels. I was thinking about how to combine these different “layers” of information and came up with this concept of “viewing-lenses”. You can drag these lenses over the picture and see different layers of information.
Imagine a touch table with tangible-sheets like in the Microsoft Second Light project… or maybe is better to be able to change the shape and size of the layers. Another idea that came to my mind was combining the lenses – one that shows the bones, another that shows the blood-vessels, put them over each other to see bones and blood-vessel at the same time.

Here is a quick flash prototype to illustrate the idea:


Taking the whole idea and mixing it with my cube interface concept could also be interesting…

First explorations in multitouch

leave a comment »

I took my paper-multitouch-sketches and transfered them into a video-sketch today. It’s still a rough concept and not all my ides work out so well, but while editing the video I already got a ton of new ideas how to change and improve the multitouch-concept. Also before the video I was thinking about adding some graphical user interface (GUI), but now I really like the simplicity of the visuals and I think it is really important for the radiologist not to get distracted by the GUI. That could be the real advantage in a touch interface for the radiologist.
