Sleep Analysis is a heavily improved feature within the Activity Center that lets users view their nightly sleep activity in detail. The analysis displays the user’s sleep summary for the previous night. The metrics showcased are: Total Hours Slept, Deep Sleep, Light Sleep, REM Sleep, and Awake time. The bottom portion of the page shows a weekly summary of total hours slept.
Bed time and wake up time are manually entered within the settings page for Sleep Analysis.
Compared to previous iterations of this display, all sleep cycle stages have been added for users to have access to all details of their sleep timeline, as well as having the tooltip interaction.
🔍 The graph features a Tap & Hold tool-tip that allows users to pinpoint an exact time and view the sleep stage for that precise minute. The interaction also works as a ‘drag’ feature, where the user can simply scroll their finger through the graph to view timestamps. This exact user interaction was also made consistent with the Heart Rate Analysis graphical interface as well.
