Magnetic fields to send data through the human body

Magnetic fields to send data through the human body

Researchers at the University of California, San Diego, are working on a technology that uses human body as a communication medium as a safer alternative to Bluetooth for wearable gadgets. According to Patrick Mercier – assistant professor at UCSD and co-director of its Center for Wearable Sensors – Bluetooth radios are not that great at transferring data when there’s a body in the way requiring more power while this doesn’t apply to magnetic fields.

Benevolent Deception in Human Computer Interaction

Benevolent Deception in Human Computer Interaction

From the abstract: “Though it has been asserted that “good design is honest,” deception exists throughout human-computer interaction research and practice. Because of the stigma associated with deception—in many cases rightfully so—the research community has focused its energy on eradicating malicious deception, and ignored instances in which deception is positively employed. In this paper, we present the notion of benevolent deception, deception aimed at benefitting the user as well as the developer. We frame our discussion using a criminology-inspired model and ground components in various examples. We assert that this provides us with a set of tools and principles that not only helps us with system and interface design, but that opens new research areas. After all, as Cockton claims in his 2004 paper “Value-Centered HCI”, “Traditional disciplines have delivered truth. The goal of HCI is to deliver value.”
