NOVELTY - The apparatus has a processor (106) that is configured to receive biometric data including accelerometer data and altimeter data from biometric sensors (110). The aspects of biometric data are displayed on display. The determination is whether biometric data indicates first contextual or environmental state based on accelerometer data and altimeter data. The type of content displayed on display is changed according to first contextual or environmental state, such that type of content includes biometric data that has been predetermined to be pertinent to first contextual.    USE - Apparatus for monitoring personal health of person during ambulatory motion state such as walking state, running state, hiking state, water sports state e.g. indoor swimming state and outdoor swimming state, aerobic exercise machine state e.g. stair climbing machine state or stationary bicycle state, and aerobic exercise state e.g. Zumba (RTM: dance fitness program created by Colombian dancer and choreographer) using data such as sleep quality, number of times awoken, sleep stage, quiescent sleep time, restless sleep time, ambulatory sleep time (all claimed), heart-beat and perspiration levels, for use with biometric monitoring device and electronic device such as watch, cell phone, personal music player, tablet and smart phone.    ADVANTAGE - The additional level of data analysis can be performed by the biometric monitoring device, thus the rate of altitude change can be analyzed to determine if the rate exceeds any realistic vertical climb rate for a human being climbing stairs unassisted by mechanical equipment. Hence, the accuracy of biometric monitoring device can be improved effectively. The biometric monitoring device can decrease the sensitivity of various input detection mechanisms to reduce the risk of accidental inputs and/or to save power. Hence, in other device states, it can be desirable to change the user input method based on the limitations of various input mechanisms in various environments.
