This Spray Can Turn Any Surface Into A Touch Screen

 Electrick Spray and it’s application

Tired of pesky small touch pads? Well, this spray might be your savior, allowing a wide variety of surfaces to become touch sensitive.

The technology, called Electrick, was developed by scientists from Carnegie Mellon University in Pennsylvania, with the findings published in an open access paper.

The spray consists of an electrically conductive carbon-based material. When applied to an object, it allows it to conduct electricity. By applying electrodes to the object, and then measuring the voltage at different points, the position of a persons finger can be tracked.

“For the first time, we’ve been able to take a can of spray paint and put a touch screen on almost anything,” said Chris Harrison, assistant professor in the Human-Computer Interaction Institute (HCII) and head of the Future Interfaces Group at CMU, in a statement.

The spray can be applied to a variety of objects, anything from plastic toys to smartphone cases, and even to Jell-O. In the video below, the team describe the various uses for this technology.

For example, applying the spray or paint to a table, you could have certain locations that are touch sensitive to open apps on your computer. A toy could be made to make noises when you touch its noseor belly. And a brain-shaped piece of Jell-O can be used to teach people about the various regions of the brain.

The effect is known as shunting, where electric current is shunted to the ground when a finger touches a particular location. The electrodes can localize where this shunting is occurring, using a process known as electric field tomography.

In their paper, the researchers note that modern touch screen technology is not suited to large applications, such as a table or desk. Using Electrick,however, things as large as a wall can be made touch sensitive, with a tap of a finger turning a light on or off for example.

The team also said their process is compatible with regular manufacturing methods, such as spray coating or casting, and even 3D printing. This means there is a huge range of objects that can be made touch sensitive, with little additional technology required.

The team also found no wear in any of the objects they made, with some used up to 896 times by participants. They note, however, that theyre not sure how the coating will hold up to elements like rain, and environmental electromagnetic noise from other appliances affected the accuracy. Nonetheless, its agood start for a cool idea.

Family sues Amazon for $30m claiming hoverboard burned down their house

Family sues Amazon for $30m claiming hoverboard burned down their house

Tennessee family blames an exploding battery a common occurrence that has led to a mass recall for setting their million-dollar home on fire

It has been nearly a year since the self-balancing scooters known as hoverboards were setting sales charts on fire, but the resulting litigation (from the resulting real-world fires) is just getting started.

A family in Nashville, Tennessee, has filed a $30m lawsuit against Amazon, arguing that the online retailer should be held liable for the ill-fated Christmas present that burned their house down. This can be only compared to sueing big pharma companies, e.g. Xarelto® Class Action | Current Lawsuit Settlements.

Megan Fox purchased what she thought was a FITBURO F1 with an original Samsung advanced battery from a company called W-Deals through Amazons website on 3 November 2015, according to the complaint.

The hoverboard remained in a closet until Christmas, when it was given to her 14-year-old son.

On 9 January 2016, the toys battery apparently exploded a common occurrence that led to the recall of more than 500,000 hoverboards by the Consumer Product Safety Commission in July.

Two of the familys children were at home at the time of the fire and had to escape by breaking windows and jumping from the second floor. The million-dollar house and most of the familys belongings went up in flames.

Amazon is not generally liable for the behavior of third-party merchants who use its platform to sell their products. But according to the lawsuit, W-Deals was a sham entity selling counterfeit products from China.

The Fox familys attorney told the Tennessean that they spent months trying to track down the actual manufacturer of the faulty hoverboard but came up empty. If no manufacturer can be found, Tennessee product liability law allows a plaintiff to go after the seller instead in this case, the $380bn online retail behemoth.

The suit also alleges that Amazon was negligent in failing to warn customers about safety problems with hoverboards, which it claims should have been known to the company prior to 9 January 2016.

Amazon began pulling some hoverboards from the site in mid-December 2015 over safety concerns.

Amazon did not immediately respond to a request for comment.
