Being Hit in the Virtual World

Virtual reality could be the next big thing in the gaming world. And while VR displays and headsets are getting more and more sophisticated, many are forgetting perhaps the biggest feature VR will need to succeed — haptic feedback. [Pedro Lopes], [Alexandra Ion] and [Prof. Patric Baudisch] from theĀ Hasso Plattner InstituteĀ is hoping to change that, with a project called Impacto: Simulating Physical Impact by Combining Tactile with Electrical Muscle Stimulation.

We’ve covered lots of haptic feedback devices over the past few years — some use mini gyros to simulate resistance, others blow air on you, but this is the first time we’ve seen one that combines muscle stimulation to really cause a physical effect.

They’re using an Oculus rift, and a Microsoft Kinect to perform the research. For their demonstration they use a basic boxing game that allows the user to feel the computer’s punches — but don’t worry, it doesn’t hit that hard!

External pinball controls for an Android tablet


This hack, which adds external flipper controls to Android pinball, is a great way to cut your teeth at Android hardware hacking.

[Ruben] decided to go with the TI Launchpad for this project. The MSP430 dev board offers serial communications via a USB connection, but it’s not quite as easy as just finding the right cable. His tablet does support USB On the Go (OTG), but the board identifies itself as an ACM device which needs to be handled differently. In order to get the tablet talking to the Launchpad he compiled a CDC_ACM module for the Linux underpinnings that make up every Android OS. In this case the module is tailored for the Allwinner A10 chip inside his model of tablet, but it shouldn’t be too hard to adapt his guide for other processors.

Of course you could go a different route and use Bluetooth for connectivity. We’ve seen several gaming peripherals that use this technique with Android devices.
