Scientists develop artwork that changes to suit your mood

Computer scientists from Bath and Boston have developed electronic artwork that changes to match the mood of the person who is looking at it.

Using images collected through a web cam, special software recognises eight key facial features that characterise the emotional state of the person viewing the artwork.

It then adapts the colours and brush strokes of the digital artwork to suit the changing mood of the viewer.

For example, when the viewer is angry the colours are dark and appear to have been applied to the canvas with more violent brush strokes.

If their expression changes to happy, the artwork adapts so that the colours are vibrant and more subtly applied.

The project forms part of on-going research looking to develop a range of advanced artwork tools for use in the computer graphics industry.

This has already resulted in software which produces highly-detailed artistic versions of photographs, and allows designers to create animations directly from digital footage.

“The programme analyses the image for eight facial expressions, such as the position and shape of the mouth, the openness of the eyes, and the angle of the brows, to work out the emotional state of the viewer,” said Dr John Collomosse from the Department of Computer Science at the University of Bath.

“It does all of this in real time, meaning that as the viewer’s emotions change the artwork responds accordingly.

“This results in a digital canvas that smoothly varies its colours and style, and provides a novel interactive artistic experience.

“This kind of empathic painting only needs a desk top computer and a webcam to work, so once you have the programme and have calibrated it for the individual viewer, you are ready to start creating personalised art based on your mood.

“The empathic painting is really an experiment into the feasibility of using high level control parameters, such as emotional state, to replace the many low-level tools that users currently have at their disposal to affect the output of artistic rendering.”

The empathic painting project was carried out with Maria Shugrina and Margrit Betke from the University of Boston.

The images used in the project were created by the researchers using advanced artistic rendering techniques which give the computer-generated artwork the appearance of having been painted onto canvas.

More information on the empathic painting project, including a video demonstration, is available on the project website (see related links section).

The research was recently presented at the fourth International Symposium on Non-Photorealistic Animation and Rendering (NPAR) conference in Annecy as part of the International Animation Festival.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
