Apple iPads earn the «most responsive screen» tablet title in tests

Gigaom

If you think Apple’s(s aapl) touchscreen tablets are more responsive than the competition, you’re right. So says Agawi, which put a number of flagship slates through its TouchMarks touchscreen benchmark test.

The test measures touch latency, or the time between a tap and opening an app, using a special bit of hardware. While the latency is generally small — less than one or two tenths of a second — you can see a big difference between products in this output graph.

Why are the Apple devices more responsive? My guess is that Apple has the most integrated approach when it comes to hardware and software. Android device makers might have hardware expertise but they’re still working with Google’s(s goog) Android software. Here’s a technical explanation of how graphics work on Android, which offers a glimpse at why touch is implemented differently in Android than it is in iOS.

European Mars-bound rover begins testing in remote desert

Gigaom

You test a drill bound for Mars in Greenland. For a robotic rover headed to Mars, the European Space Agency turned to an even more remote location: the Atacama desert in Chile.

The ESA ExoMars rover is scheduled to land in 2019 on Mars, where it will search for signs of life. IEEE Spectrum caught that the ESA began testing the rover this week in the Atacama Desert. The location is very dry with reddish soil and zero vegetation, which makes it an excellent on-Earth mimic of Mars’ surface and an excellent place to test a Mars rover.

Atacama Desert

ExoMars will be expected to perform more autonomous tasks and move faster than NASA’s Curiosity rover. As a result, that’s a big focus of the testing going on in the Atacama desert. ESA will have limited contact with the rover once it lands on Mars, which it will replicate during the…
