phyphox 1.0.6¶

24.02.2017

Changes for both Android and iOS¶

New experiment: Inelastic collision.
New timer experiments: Motion stopwatch, proximity stopwatch and optical stopwatch. The existing acoustic stopwatch has been moved to this section.
Support for the proximity sensor.
Raw sensor experiments now also give the absolute value of 3D data.
The info button at the top now opens a small menu with links to our FAQ, help and experiment collection.
Added resonance page to the experiments “spring” and “pendulum”.
The “pendulum” experiment now has a page, which allows estimating the length of the string.
Added a third view to the “sonar”, plotting the correlation against the raw time axis.
Performance improvements for “sonar” and “acoustic stopwatch” for slower devices.
The “elevator” experiment now also shows the acceleration using the accelerometer.
The remote interface starts in a new “narrow” layout, similar to a phone screen. You can still switch to the old full-screen layouts via the menu of the remote interface.
The rate limit for the raw data experiments has been removed, so they acquire data at the maximum rate allowed by your device.
Fix: Graph scaling not applied on remote interface.

We now read the recording from the mic in smaller chunks to improve the timing of the analysis cycle.
Default margins removed from all view elements as these are now controlled by the new separator view module. (See file format changes below.)
Name the sensor which is not available when trying to open an experiment.
Fix: Crashes when experiments use string icons with less than three character.
Fix: Rare crash when showing hint tooltip.
Fix: Do not show save-locally dialog if the experiment was not loaded successfully. Trying to save in such cases led to a crash.
Fix: The optimization for the analysis assumes it can skip empty buffers as there is no data to be processed, resulting in problems, when a buffer is empty because it has been cleared intentionally. Instead we now keep track if a buffer has been touched.
Fix: When averaging, the first sensor value is returned immediately without averaging.
Fix: The edit box in the experiment “Magnetic ruler” resets to the default value.
Fix: Repeatable inputs were not mapped correctly if they were not used in the first period of repeatable inputs. This affected the rangefilter in a way, that it would not behave correctly if the second input should be filtered, but not the first one.

Audio recordings are buffered internally and only exposed to the analysis buffers just before an analysis cycle starts. This way, it is guaranteed, that the buffer will not be changed during the analysis process and you do not need to create a local copy. This makes it consistent with the behavior of the Android version.
Display a hyphen instead of “NaN”.
Added a default text when sharing a screenshot. This hopefully prevents some third-party apps from inserting the image file path as default text.
Fix: Range filter does not work correctly in cases in which the first value of the second input is filtered.
Fix: Remote access stops working after leaving the app and returning to the existing session.

New absolute output for all sensors, so you do not have to calculate it yourself in your analysis.
New separator view element. This allows to add margins or lines to group your views.
New analysis module: subrange. This simply returns the values within an index range. Much faster than using the rangefilter for this task.
The analysis modules “if” and “append” as well as the view “button” now allow a new input type. Besides “value” and “buffer”, you may now set them to “empty”, practically being a constant buffer of length zero.
Slightly change behavior for “if” module: If the output is flagged to be cleared before writing, this is only done if the condition for an input has been met. This means, that the output is not cleared if there was no input for a certain case and you can conditionally clear an output by assigning an input of type “empty” to a case.
