As sensor readings are received from a hardware sensor, each sensor reading is stored within a buffer along with a system timestamp of a system clock indicating when the sensor reading was received. Each sensor reading includes a sensor timestamp of a sensor clock indicating when the sensor reading occurred at the hardware sensor. Responsive to receipt of each sensor reading, a synthetic timestamp compensating for skew between the system clock and the sensor clock is generated and applied to the sensor reading. The synthetic timestamp is generated based on an average skew of the sensor readings within the buffer and an initial system timestamp indicating when a first sensor reading was received.

According to aspects of the present disclosure, there are provided methods and apparatus for providing a user characteristics determination module for use with a head-mountable display device, comprising: a biological characteristics handler to determine whether biological sensor data is indicative of a predefined biological characteristic of the user; and determination logic to determine and output a predefined response to the determined biological characteristic of the user.
