Abstract: A method may include storing, using a data management application on a user device, personal data that is associated with a user and a first data variable. The method may further include obtaining, from a requesting application and by the data management application, a data request for a second data variable. The method may further include determining, by the data management application, whether the first data variable associated with the personal data matches the second data variable associated with the data request. The method may further include transmitting, by the data management application and in response to determining that the first data variable matches the second data variable, the personal data to various intermediary nodes. One intermediary node among the intermediary nodes may transmit the personal data to the requesting application using a distributed ledger.

Abstract: A method is provided for device interaction and identification by detecting similar or synchronous movements of two or more electronic devices using two or more Movement Data from two or more involved electronic devices to interact with each other and detect when the movement or motion of involved devices corresponds with certain multi-device gestures or activities.

Abstract: The aim of the present invention is to provide low-power gesture control method for mobile and wearable devices for interacting target devices. Furthermore, this invention presents a take on solving the modality switching problems known from prior art, where one modality can be used to activate another.

Abstract: The aim of the present invention is to provide a method to solve the common drift problems and 3D orientation errors related to the use of orientation data of a mobile or wearable device and target system and for using mobile or wearable device as a Human-Machine Interface (HMI) using Inertial Measurement Units (IMUs) and potentially other sensors (for example cameras and markers, radar systems) as input data to convert user's motion into an interaction, a pointer on the screen or a gesture. The contribution of this invention is a solution for well-known problems related to the use of IMUs and motion sensors as input devices for user interaction in general, as well as specific embodiments and application scenarios of these methods where wearable and/or mobile devices are used to control specific interfaces.
