Nexight is the name of  my Master Thesis in Interaction Design at Umea Institute of Design, Sweden in close collaboration with Philips Design, Eindhoven. Nexight is a design concept for the radiologist reading room. My idea was to bring Natural Interactions to the radiology department.

Multitouch/multiscreen interface:

3D interface prototype:

Screenshot from the 3D interface. You can see how the radiologist can use the pen in any direction to slice different layers from the current view. This enables the radiologist to see these different layers in relationship.

I generated this 3D model of a childs head from a real MRI scan. I later used the MRI scan and 3D model in my prototypes.

Prototyping

The 3D pen was a critical part of the 3D interface. Even though this is not a proposed industrial design, I made many revisions of the pen based on feedback and problems with the previous versions. Inside there is two leds for the 3D tracking and a pushbutton for controlling the mode of the 3D interface. It is connected to the computer with an Arduino board.

interface screenshots

as you can see the pen is used to slice the 3D object in various ways.

The red a blue leds were used to enable video tracking the pens position in 3D

arduino

this arduino board was connected to computer and 3D pen

video tracking

2 cameras were used to track all 3 axis of the pens position

evolution of the prototype

the 3D pen went through a series of revisions. on the left is the final version.

code

I used vvvv (a visual progamming language) to do the video tracking and render the interface

assembly

arduino board is connected to the push button and 2 leds inside the pen

From the beginning of the project I relied heavily on prototypes to evaluate and test my ideas. here are some of the prototypes that lead to my final design:

Research

CT scanner during the visit to medical center in Utrecht

Body worlds exhibits are similar to the way CT scans are made. slice by slice.

Nuclear medicine is used to scan blood flow and brain activity.

Case studies presentation room in Umea Hospital, Sweden.

various non-traditional interfaces (concepts) for radiologist

3D interface for virtual colonoscopies. looking in all directions at the same time.

visit to Utrecht medical center, reports are still written by hand and scanned later.
