Abstract: A processing device includes: a detection unit configured to detect input information representative of a sequence of input signals for a video game that are input by a user using one or more input controls; an identification unit configured to identify one or more input signal variations in dependence upon one or more differences between the detected input information and predetermined input information representative of one or more predetermined sequences of input signals for the video game; a generation unit configured to generate assistance information in dependence upon the one or more identified input signal variations; and a provision unit configured to provide the generated assistance information to the user.

Abstract: A method of improving accessibility for the user operation of a first application on a computer includes the steps of taking one or more measurements of a current user's interaction with an application on the computer, comparing the one or more measurements with expectations derived from measurements from a first corpus of users, characterising one or more needs of the current user based upon the comparison, and modifying at least a first property of the first application responsive to the characterised need or needs.

Abstract: A method for protecting personal space in a multi-user virtual environment includes the steps of generating an avatar for a target user in the multi-user virtual environment, determining a relationship score between the target user and a peer user, creating a personal space around the avatar of the target user, wherein the dimensions of the personal space is computed based on the relationship score with the peer user, detecting the peer user's avatar crossing the boundary of the personal space, and applying rules to the peer user to restrict his/her interactions with the target user.

Abstract: A haptic feedback method includes: providing a wearable haptic feedback device comprising one or more bone-conduction haptic feedback units, and driving the one or more bone conduction haptic feedback units with at least a first signal processed using a bone conduction head related transfer function, ‘bHRTF’.
