MOUTH HAPTICS FOR VR HEADSETS

Mouth Haptics for VR Headsets Are Just Going To Be Used for Kissing

 

Scientists at the Futures Interfaces Group at Carnegie Mellon University added ultrasonic devices to a standard VR headset. They point at the mouth and target pulses and swipes at the lips, teeth, or tongue. Most haptic devices currently involve our hands and fingers, like cell phone menus and VR accessories. The mouth is the second most sensitive area, thus the researchers focus for enhancing VR. It also means their accessory mounts to the headset and doesn’t add any other equipment.

At the very origin of our ideas of about learning, as well so much else that defines our culture, lies the extraordinary flowering of thought and discovery centred on Athens from the fifth to the second century BC. This episode takes us back to the very earliest group of thinkers this series will cover, the ancient Greeks.

India privacy

A new government order will force virtual private networks to store user data for five years or longer.

The directive isn’t limited to VPN providers. Data centers and cloud service providers are both listed under the same provision. The companies will have to keep customer information even after the customer has canceled their subscription or account.

India has a history of applying a heavy hand to online activity.

In April, India banned 22 YouTube channels. In 2021, Facebook, Google Twitter ended a tense stand-off with the Indian government when they largely complied with the government’s expanded control over social media content in the country. In 2020, the country banned over 200 Chinese apps, including TikTok, and ultimately banned 9,849 social media URLs.

Learning in Metaverse

new study co-authored by Richard Mayer,

The study took place with about 100 middle school students taking a brief “virtual field trip” to learn about climate science. Some students experienced the field trip while wearing a VR headset, while others watched the same material in standard video on a computer screen.

“higher ratings of presence, interest, and enjoyment,”

The paper noted an obvious logistical benefit to virtual field trips over getting on a bus for an in-person outing. “Virtual field trips make it possible to experience things that are too expensive, dangerous, or impossible in the real world,” it says. The experiment did not address the difference in educational value between a real-world field trip and a virtual one.

for programs like nursing, pharmacy and medicine, VR seems promising for teaching some skills, as a piece of a broader curriculum that includes in-person hands-on learning as well.
