San Francisco-based startup Fove has developed eye-tracking for virtual reality -- that kernel of technology many feel is key for the illusion of becoming immersed in a setting. Or use a death stare to shoot down virtual spaceships. Watch a movie of a forest or a room and be able to look around wherever you want. "It allows you to go inside the world that's behind the display," said Yuka Kojima, Fove's co-founder and a rare female chief executive in male-dominated Japan Inc. Fove, which comes from "fovea," the part of the eye with the sharpest vision, from "field of view," and the word's similarity with "love," has devised a way to use tiny infrared sensors inside headset goggles to monitor the movements of a wearer's pupils. It's a small company, founded in 2014, with offices in Tokyo, San Francisco and Los Angeles, and employing just 17 people.

See machine learning in action during "A Glimpse into the Future of Email Marketing – Reaping the Benefits of Machine Learning," featuring Kath Pay, Dela Quist, Skip Fidura and Jeremy Swift, May 19 at the Email Innovations Summit in Las Vegas. "Machine learning" has moved out of science fiction and into real-life applications, like powering Tesla cars that run on autopilot and robots that can beat humans at the Japanese game of Go. For marketers, it gets them closer to their email nirvana: true 1:1 personalization on a mass scale. Machine learning, at its simplest, is a method of data analysis that allows computers to learn – to analyze, predict and act – without explicit instructions or programming. That last phrase – "without explicit instructions or programming" – highlights the difference between today's rule-based marketing automation and systems that use machine learning.

"I wish I could touch you," Theodore says, laying in bed. Until she speaks up, tentatively. "How would you touch me?" It's a famously poignant scene from the movie Her, as the character Theodore is about to make vocal love to an artificial intelligence living in his ear. But according to half a dozen experts I interviewed, ranging from industrial designer Gadi Amit to the usability guru Don Norman, in-ear assistants aren't science fiction. In fact, a notable pile of discreet, wireless earbuds enabling just this idea are coming to market now. Sony recently released its first in-ear assistant, the Xperia Ear. Intel showed off a similar proof-of-concept last year. The talking, bio-monitoring Bragi Dash will be reaching early Kickstarters soon, while fellow startup Here has raised 17 million to compete in the smart earbud space.

A new material being researched could make shape-shifting robots real, but let's hope they aren't as violent as the Transformers from the movies. Researchers have developed a flexible material that can stretch when heated and will allow robots to change shapes. The material, which can also be rigid, is a mix of elastomer foam with a soft metal alloy. With the material, robots could become more versatile. Most robots are rigid, much like human skeletons, but by morphing into new shapes, they could be used for new tasks.

Apple product events typically spark anticipation among tech bloggers and the company's hard-core fans. Monday's event, though, is drawing less excitement than some previous product launches. Apple is expected to announce a smaller, 4-inch iPhone and a smaller version of the iPad Pro tablet. But there's been no hint of any blockbuster developments, such as last year's highly anticipated Apple Watch debut. Despite speculation that Apple is working on a self-driving car or some new virtual-reality device, those are likely years away.

Save the "Star Wars" franchise? Everyone's favorite "Star Wars" actress, Daisy Ridley, told The Hollywood Reporter at this weekend's Empire Awards that there "have been conversations" about her wielding the storied video game heroine's dual pistols in an upcoming reboot. Conversations, however, don't mean that Ridley's casting is a done deal, as the 23-year-old actress has yet to receive an official offer. "I'm waiting for someone to say'I want you, let's do it,'" she said, explaining that the project doesn't have a script yet. But Ridley is committed to the role, even with her busy "Star Wars" schedule -- she is currently filming the eighth installment in the sci-fi epic. If the opportunity presented itself, Ridley would be happy to make time for "Tomb Raider," telling THR that "I'm trying to fill up my calendar."

As the velocity of the rate of change in today's technology steadily continues to increase, one of the contributing factors behind this acceleration the rise of artificial intelligence (AI). "Smart" attributes and functionalities are being baked into a multitude of systems that are affecting our lives in many visible and, at other times, transparent ways. Just to name one well-known example of an AI-enabled app is Siri, the voice recognition system in the iPhone. Two recent Subway Fold posts have also examined AI's applications in law (1) and music (2). However, notwithstanding all of the technological, social and commercial benefits produced by AI, a widespread reluctance, if not fear, of its capabilities to produce negative effects still persists.

Artificial intelligence (AI) may conjure up far-fetched ideas of robot assistants, or perhaps an all-seeing presence like HAL 9000, the sentient machine in the movie 2001. But the likelier truth is that AI will come in the form of software running in your data center. And it will be coming very soon: Research firm Gartner predicts that "smart machines" will have a widespread impact on business within the next four years. In general terms it's likely that AI will be able to help IT departments do their job - and help businesses be more productive – by ensuring that "processes get applied, stuff is accurate, errors are eliminated, and compliance is met," according to Dr Stuart Anderson, a research fellow at the Future of Humanity Institute at the University of Oxford. It will also be quite unremarkable, according to some.

There is no meaningful sense in which there is an abstract notion of purpose. That is, purpose is something that comes from history. One of the things that might be true about computation, might be true about our world, that would be disappointing, is maybe we go through all this history and biology and civilization and so on, and at the end of the day, the answer is 42 or something. That's the end, so to speak. We got to the answer.
