Car projector understands gestures and human speech

16.08.2014

California-based startup Navdy has developed a projection system of the same name that can be used in all cars. Unlike other similar Head-up-Display (HUD) products, the novelty not only displays useful information, such as navigation tips and current speed, but also allows you to control some smartphone functions using voice and gestures.

The compact Navdy device, controlled by a dual-core processor and operating system Android 4.4, is mounted on the steering column in front of the driver. The projector displays a high-resolution image on a 5,1-inch transparent screen, which is not located on the windshield, like the Garmin HUD model, but on the device itself. At the same time, the person driving sees an image that seems to be at a distance of about two meters from his eyes.

Navdy, connecting to the on-board computer via the OBD-II diagnostic connector (available on all modern cars), projects the current speed, fuel level, power reserve and other regular information. This gadget can act as a navigator. For this, synchronization with an iPhone or Android smartphone is available wirelessly (Wi-Fi 802.11 b/g/n or Bluetooth 4.0).

Navigation is carried out using the Google Maps service, but in the future the developers promise to add support for other mapping services such as Waze and Apple Maps. Instructions with driving directions for drivers are clearly drawn and are not removed during an incoming call or message.

Information about the caller is also displayed on the projection surface. With a movement of the hand, the car owner, without being distracted from driving the car, can accept the call or reject it. The built-in infrared camera is responsible for gesture recognition. Incoming messages can be read aloud or set to only appear on the display when the vehicle is at a complete stop.

Navdy also has voice control built on the popular Apple Siri and Google Now services. With the help of voice commands, you can dial a subscriber's number, control the audio system, set a route, dictate an SMS message or a note for a Twitter blog. At the same time, the microphone is equipped with DSP (Digital Signal Processing) technology to suppress unwanted noise.

The device can be used comfortably while driving on rough roads: image stabilization is provided by an accelerometer and an electronic compass. The built-in light sensor will automatically adjust the brightness of the picture depending on the intensity of ambient light.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Growing wood without a tree 12.08.2022

American scientists from the Massachusetts Institute of Technology have invented a way to grow wood in the laboratory.

To do this, the researchers first isolated cells from the leaves of young Zinnia elegans plants. The cells are cultured in liquid medium for two days, then transferred to a gel-based medium that contains nutrients and two different hormones. Adjusting hormone levels at this point in the process allows researchers to fine-tune the physical and mechanical properties of the plant cells that grow in this nutrient-rich broth.

The cell culture solution is then extruded into a specific shape using a 3D printer and left in the dark to incubate for three months. At the end, the material is dehydrated and sent for research.

"The idea is that you can grow plant materials in exactly the form you need, without the need for any kind of mechanical processing that consumes energy and produces waste," the scientists say.

Scientists hope that with the help of their technology in the future it will be possible to refuse cutting down trees for the manufacture of wooden products, which is important for preserving the environment.
