The developments in version 3.4 of FizziQ are as follows:
- Choice of the fundamental frequency calculation algorithm (Yin and Autocorrelation)
- Acceleration of luminance calculations
- Line and dot PDF charts for spreadsheets
- New sound sin the library to study music (scale, octaves, non harmonic sounds, notes)
- Added languages (Italian, Danish, Estonian, Finnish, Hungarian, Norwegian, Swedish, Malagasy)
This version makes it possible to recognize and acquire data from external sensors via Bluetooth BLE. The use is particularly interesting with micro: bit and Arduino cards. For the micro: bit card, FizziQ receives the various GATT services including the UART format. For Arduino and the other boards, the data exchange is done through the UART service. FizziQ recognizes a large amount of data and automatically includes the corresponding icons and units.
Multilingual version (fr, en, de, nl, es, pt)
New possibilities on triggers such as timing.
Improvements on protocol management with the possibility of automatically creating beautiful PDF worksheets including the QR code or reading text files
Improvements on the synthesizer and new sounds in the sound library (tuning forks, white noise) for new experiences
Adding luminance. Using the camera to calculate the luminance. The luminance is proportional to the light intensity but, unlike the illumination measurement, does not take into account the surface of the light source. It is the visual feeling of the light intensity.
FizziQ calculates the relative luminance, i.e. the luminance compared to a reference. The luminance is calculated as the average of the red, green and blue components detected by the smartphone camera over the entire image and referred to the calibration value. Calibration is necessary because smartphones constantly adjust the image capture parameters so that the image is the best possible, Calibration allows you to fix the image acquisition parameters and therefore to be able to compare the luminance that you observe relative to the initial luminance.
Two types of luminance are calculated, the local luminance and the global luminance . Global Luminance calculates the average luminance of all pixels in the image captured by the camera. The local luminance calculates the value on the central pixels of the image. The measurement is updated at a frequency of approximately 10 Hz, available on iOS and Android.
Addition of tables. User can create a table with two columns and multiple rows to enter values just like he would on an Excel table. He can easily graph the data.
Addition of the Colorimetry module (colors, spectrum and absorbance):
FizziQ uses the photographic detector present in smartphones to calculate various parameters that characterize the color reflected or transmitted by objects in the field of the camera.
The Color screen gives you a lot of information about the color of the center of the image: a sample of the color perceived by the sensor and its common name, the spectrum in% of the maximum value of the components red, green and blue that make up that color, the tint on the HSV scale, and the intensity of that tint.
The color spectrum gives the composition of the red, green and blue components of the camera's Bayer filter. This filter allows wavelengths to pass around the 460 nm (blue), 550 nm (green) and 640 nm (red) wavelengths.
Absorbance measures the decimal logarithm of the ratio between the reference light intensity determined during calibration and the transmitted light intensity.
Colorimetric measurements are updated at a frequency greater than 10 Hz, available on iOS and Android.
