TLDR
In this article, the authors describe methods for providing real-time feedback to an end user of a mobile device as they are interacting with or manipulating one or more virtual objects within an augmented reality environment.Abstract:
Methods for providing real-time feedback to an end user of a mobile device as they are interacting with or manipulating one or more virtual objects within an augmented reality environment are described. The real-time feedback may comprise visual feedback, audio feedback, and/or haptic feedback. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may determine an object classification associated with a virtual object within an augmented reality environment, detect an object manipulation gesture performed by an end user of the mobile device, detect an interaction with the virtual object based on the object manipulation gesture, determine a magnitude of a virtual force associated with the interaction, and provide real-time feedback to the end user of the mobile device based on the interaction, the magnitude of the virtual force applied to the virtual object, and the object classification associated with the virtual object.read more

Gaming device with volumetric sensing
TL;DR: In this paper, a method for enhancing detection of a user's hand relative to a head-mounted display (HMD) is described, which includes sensing a disrupted portion of energy by sensors integrated within a pad device.
Patent
Touch sensor detector system and method
TL;DR: A touch sensor detector system and method incorporating an interpolated sensor array is described in this article, which utilizes a touch sensor array (TSA) configured to detect proximity/contact/pressure (PCP) via a variable impedance array (VIA) electrically coupling interlinked impedance columns (IIC) coupled to an array column driver (ACD).
Patent
Eye-tracking enabled wearable devices
TL;DR: In this article, a method for mapping an input device to a virtual object in virtual space displayed on a display device is described, based on the user's gaze direction being directed to the virtual object.
Patent
Wearable Electronic Device
TL;DR: In this article, a method executed by a head mounted display moves a virtual object with respect to a real object in order to maintain the virtual object in a field of view of the HMD display.

TL;DR: In this article, a method and apparatus for determining forces to be applied to a user through a haptic interface is presented. The method includes the steps of generating a representation of an object in graphic space, sensing the position of the user in real space and calculating a force to be imposed on the user by the haptic interfaces and the user's fiducial object.
