Computer mouse controls biometric parameters

07.12.2014

A team of specialists from the company MionixLabs, whose activities are focused on the development of gaming peripherals, introduced the world's first "smart" mouse with a focus on the physiological aspect. NAOS QG is made on the basis of the top "rodent" Mionix NAOS, designed for use by professional gamers. The improved model has received a set of additional features, but all of them, no matter how strange it may sound, do not affect the improvement of the gameplay and increase the skill of gamers.

But the owner of NAOS QG will now be able to track heart rate readings, and the sensors built into the manipulator will read from his palm and record the results of the galvanic skin response (GSR), or, as it is also called, the electrical activity of the skin. By the way, the algorithm of the polygraph - a lie detector - takes into account GSR indicators along with measuring the pulse, processing ECG data and other physiological variables.

The obtained statistics can be used as a psychophysiological indicator and draw conclusions about the current state of a person, operating with such manifestations of the emotional state as tension, anxiety, and also fix a sharp increase in mental activity. All of these parameters are directly related to external stimuli and the internal state of the player, which is reflected in the information about the electrical activity of the skin. In a state of appeasement, tonic electrocutaneous resistance tends to a maximum value, and when awake and active, like playing on a computer, they decline.

All information collected by the system can be displayed in the form of translucent indicators of current indicators so that the gamer, without looking up from game battles, has the opportunity to compare his body's reaction to what is happening in the virtual space.
On the other hand, do gamers really need such a gadget and how useful will heart rate and GSR measurements be for them? The issue is quite complex and highly controversial.

The developers, as an example of the performance of the system they created, published on their website a graph of the heart rate of five gamers, whose readings were taken for 30 minutes. When the number of heart beats per minute of one of the participants in the experiment reached its peak values, the software took a screenshot from the game to understand the virtual factors that caused the change in heart rate.

The authors of the project "smart" computer mouse NAOS QG decided to find funding for their development on Kickstarter. The startup, called "Quantified Gaming - know more, game better", needs to raise $100 for the successful commercial implementation of the idea, of which $39 was already transferred 22 days before the end of the campaign.

The minimum cost of NAOS QG for crowdfunding participants who managed to place a pre-order on the site will be $79, and the manipulator will go to retail for $99. Deliveries of the device, subject to the receipt by the developers of the required amount, are scheduled for July 2015.

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

More solar panels in Tokyo 16.09.2022

The Tokyo Metropolitan Region Government has announced a new policy that mandates the installation of solar panels on some of its new homes as part of a move to promote the use of solar energy. The initiative is scheduled to start in 2025 and will be the first of its kind in Japan, according to The Japan News.

About 50 developers building buildings with a total area of at least 20 m2 per year will fall under the new rules requiring the installation of solar panels.

However, the proportion of solar panels required for installation will differ from area to area, taking into account the degree of insolation in a particular place. For example, if in the districts of Chioda and Chuo, where many tall buildings are located, 30% of the roofs should be covered with panels, then in low-rise areas - up to 85%. Since the life cycle of panels is about 20-30 years, the county government will also set up a system to promote their recycling with an eye to preparing for the mass replacement of panels in the future. Panel leasing is not excluded, as well as subsidies for home buyers and other benefits.

According to the publication, some developers are expressing concern about additional costs that can raise the cost of housing. In response, with the start of the program, the authorities promise to strengthen support measures.

Starting in the spring of 2025, new homes across the country must meet certain energy efficiency standards - for example, developers must use materials with a high level of thermal insulation. The local authorities decided to launch their "solar" initiative at the same time as the start of the implementation of national standards in order to make it easier for builders.

Tokyo Metropolitan Governor Yuriko Koike said she hopes the new initiative will be a turning point in history, after which it can be said that "Tokyo has changed."
