Danish-Chinese joint-venture ready with new prototypes for next generation screens

In 2015, the International Year of Light and Light-based Technologies, the science publication Videnskab.dk is taking the opportunity to shine the spotlight on Danish research. WaveTouch, a technology invented by researchers at the technical university DTU and the Danish company OPDI, has the potential to revolutionise touchscreens.

The story of the invention’s genesis goes back to 2006, when Jørgen Korsgaard, the head of OPDI, asked the DTU researchers Henrik C Pedersen, Michael L Jakobsen, and Steen Hansen to help him develop a touch panel for a cooking hob that you could use with wet hands.

Pressure-sensitive and cheaper
The result was WaveTouch. Whereas conventional touchscreens work on the principle of the finger completing a circuit on a tiny, invisible electronic grid, WaveTouch is an optical technology that involves directing light into a piece of glass that gets activated when it is touched.

Some of the advantages, along with being usable with wet hands, are that WaveTouch can feel how hard the screen is pressed and it is significantly cheaper.

In 2013 the Chinese company O-Net Communications joined OPDI in a joint venture and invested 3 million US dollars for a 40 percent share of the WaveTouch technology.

O-Net WaveTouch has developed a prototype for use in a watch and is soon to release a prototype for a car navigation system. The company has a team of four in Tåstrup and a further two in Shenzhen, China.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
