How much can you move your finger?
“Magnetic sensor type finger tapping device UB-2” is a that allows you to understand the state of the brain through finger tapping movements * 1 new tool .
The fingers are said to be the second brain, and many areas of the brain are involved in the work of the fingers.
It is expected as a method to know the health condition of the brain, and since it can quantify the skillful motor function of the fingers, it can be used for research purposes in the fields of healthcare, rehabilitation, life support, etc.
* 1 Never before: A product with a new concept not found in other companies. As of October 2019, according to Maxell research
1. 1. Easy connection
It is a simple configuration that just connects the main unit and a personal computer using a USB cable.
commercially available Bluetooth ® Bluetooth by using a adapter ® connection is also possible .
2. 2. Palm-sized compact and lightweight design
Because it is compact and has a compact and lightweight design that is convenient to carry,
It can be measured anywhere.
It can be used in various scenes according to the research purpose.
３. ｢Just Tap｣
The attached application “JustTap” is used for measurement.
Select from two measurement modes, simple mode and detailed mode, and in the case of simple mode,
The measurement is completed by just performing a tapping exercise for 30 seconds.
Accurate measurement of finger movement with a magnetic sensor attached to the fingertip
1. 1. Measurement device utilizing magnetism
The change in magnetic force that fluctuates due to the opening and closing movement of two fingers (finger tapping movement) is converted into an electric signal and converted into the distance between two fingers.
2. 2. Reproduce finger movements with waveforms
A magnetic sensor attached to the fingertip samples the distance between two fingers at regular intervals to visualize the movement of the finger.
Features * 2 (up to 248) can be calculated and analyzed immediately
1. 1. Calculation and analysis of features of measurement data
The sampled distance data is time-differentiated, the velocity and acceleration are calculated, and the features that indicate the characteristics of finger movement are calculated and analyzed.
<Items that can be analyzed (example)>
The attached application “Just Tap” can analyze 44 types of features.
The measurement pattern of tapping motion can be set by combining left hand only, right hand only, both hands at the same time, and both hands alternating.
With these combinations, up to 248 features can be calculated.
2. 2. Visualize measurement results
The value average value * 3 compared with the is displayed as a radar chart for each feature.
Easy-to-read display using numerical values, figures, and colors supports result judgment.
* 2 Feature: An index showing the characteristics of the waveform of tapping movement, and showing the characteristics of finger movement.
* 3 Average value: A value calculated based on the data acquired by Maxell. As of October 2019, according to Maxell research
Free to use, detailed analysis of measurement data is possible, and new features can be created according to the purpose.
The measurement data is output to a CSV file as quantitative numerical values such as distance, velocity, and acceleration.
From these numbers, you can see more detailed numbers and trends in hand features that cannot be seen by display or visual inspection on the application.
Up to 248 features can be calculated. It is also possible to create a new feature amount according to the purpose.
