A small idea for the MTA to help commuters use the entire train and not just a few cars.
I had an idea while stuffed into a metal box on my commute this morning.
NASA figured out how to computerize subvocal speech (and control rovers with it!) 10 years ago, but we still talk out loud to our phones. There are a lot of reasons why the technology isn’t perfected, but I’m surprised we haven’t seen more of these sort of user experiences lately.
This paper contributes results from an empirical study of on-skin input, an emerging technique for controlling mobile devices. Skin is fundamentally different from off-body touch surfaces, opening up a new and largely unexplored interaction space. We investigate characteristics of the various skin-specific input modalities, analyze what kinds of gestures are performed on skin, and study what are preferred input locations. Our main findings show that (1) users intuitively leverage the properties of skin for a wide range of more expressive commands than on conventional touch surfaces; (2) established multi-touch gestures can be transferred to on-skin input; (3) physically uncomfortable modalities are deliberately used for irreversible commands and expressing negative emotions; and (4) the forearm and the hand are the most preferred locations on the upper limb for on-skin input. We detail on users’ mental models and contribute a first consolidated set of on-skin gestures. Our findings provide guidance for developers of future sensors as well as for designers of future applications of on-skin input.
3 Girls Won The Google Science Fair With A Bacteria-Based Plan To Solve The Food Crisis
Three young girls won the Google science fair on Sept. 22 with their innovative way to feed the world: treat plants with bacteria to help farmers grow more food, faster — without genetic modification.
"By the year 2050 we actually need 50 percent more food just to feed everyone," Emer Hickey, one of the three winners, told Scientific American.
Hickey worked with her classmates Ciara Judge and Sophie Healy on their project. The three teenage girls, who live in Ireland, were simultaneously learning about plants and world hunger. Their project “Combating the global food crisis: Diazotroph Bacteria As a Cereal Crop Growth Promoter" aims to tackle issues of world hunger by exploiting a curious relationship they found between bacteria and certain plants.
After 11 months of hard work and dedication, the three teen microbiologists discovered that they could make crops yield more food and shorten the time it takes a plant to sprout from a seed — a process called germination. They shorten this time by infecting the crops with a bit of bacteria that’s been known to be advantageous to other crop plants.
Their results have huge implications for increasing agricultural productivity and easing world hunger.
The key to their success is a type of bacteria called rhizobia, which lives inside nodules, or the little nubs you sometimes see on plant roots. While we usually think of bacteria as dangerous, these are actually helpful to the plants. By converting nitrogen from the air into helpful compounds like ammonia, the bacteria aid plant growth.
