Abstract

A method includes: supporting a normal operation mode, during which functionalities of a portable apparatus are available through an operating system of the apparatus, wherein the operating system includes a plurality of layers including a kernel and library functions layer; supporting a limited operation mode during which the apparatus is configured to execute a physical activity algorithm based on physical activity data corresponding to a physical activity session performed by a user of the apparatus, wherein the physical activity algorithm applies a direct low-level hardware access bypassing at least the layers above the kernel and the library functions-layer; and switching between the normal operation mode and the limited operation mode.

Dependent claims

A smartwatch comprising:

a motion sensor configured to measure a motion;
a positioning unit configured to obtain a location;
an optical heart activity sensor configured to optically measure a heart activity;
a display configured to act as a user interface;
a touch controller configured to make the display touch sensitive;
a wireless interface configured to receive data;
one or more memories including computer program code;
and
one or more processing units to execute the computer program code to cause the smartwatch to perform operations comprising:
supporting a normal operating system operation mode during which the smartwatch is configured to run an operating system, control functionality of the display and the touch controller, display notifications regarding incoming calls, messages and social media updates received via the wireless interface, and measure physical activity using data obtained from the motion sensor, data obtained from the positioning unit and data obtained from the optical heart activity sensor;
supporting a limited exercise operation mode during which the smartwatch is configured to control functionality of the display, switch off the touch controller, enable the wireless interface to establish a wireless link with an external physiology exercise sensor, suppress reception of notifications related to incoming calls, messages and social media updates via the wireless interface, and measure physical activity using data obtained from the motion sensor, data obtained from the positioning unit and data obtained from the optical heart activity sensor during a physical activity session performed by a user of the smartwatch;
and
switching between the normal operating system operation mode and the limited exercise operation mode.
