Abstract: Disclosed is an apparatus for providing information relating to a cognitive state of a first individual. The apparatus comprises a measurement unit operable to measure the first individual's hand movement in a personal axis, the personal axis being an axis from the hand to the first individual. The apparatus comprises a recording module configured to record data from the measurement unit. The apparatus comprises a machine learning module configured to provide information relating to the cognitive state of the first individual using a set of first movement data based on the data recorded by the recording module. The set of first movement data preferentially relates to movement of the hand of the first individual in the personal axis over movement of the hand of the first individual in axes orthogonal to the personal axis.

Abstract: In one embodiment there is disclosed an apparatus (1) for determining a cognitive state of a user of a mobile device (2), the apparatus (1) comprising: the mobile device (2), an IMU (6) in the mobile device (2), optical output means (5.1) in the mobile device (2), for optically giving out information to the user, a camera (3) in the mobile device (2), for recording images of an environment of the mobile device (2), an augmented reality module (14), for generating an augmented reality environment (AR) shown via the optical output means (5.1) and based on the environment (PE) of the mobile device (2) captured by the camera (3), characterised in that the apparatus (1) further comprises an enabling module (15), for enabling an input element (10.1) in the mobile device (2) once the augmented reality environment is shown, said enabling depending on data measured by the IMU (6), said input element (10.
