With this technology, technologies such as multimedia, sensors, and wireless communication can be embedded in people's clothing, and various interaction modes such as gestures and eye movement operations can be supported, and the smart devices that can be directly worn are mainly explored and created. With the rapid development of computer hardware and software and Internet technology, the form of wearable smart devices has begun to diversify, and has gradually demonstrated broad application potential in the fields of industry, medical health, military, education, entertainment and so on.
Head-mounted visual devices allow you to do other things while watching the screen in the real world. It allows you to take notes while listening to the professor's lesson, rather than continually squinting between the blackboard and the notebook. You can read the email while you are on the street without hitting people.
With a wearable device you have the equivalent of a library of entire reference books that you can access instantly. Maps and e-books are similar to the frequently used Webster and classification dictionaries. With 5 gigabytes of drive support, putting the Conrad Encyclopedia on a wearable computer is trivial and provides access to a vast amount of information in real time.
All recorded notes, travel records, class, business meetings, will always be with you. With a fast search engine, you can call up the information you need in seconds, which is better than pulling a dusty notebook out of your attic. You won't have to find a pen and a piece of paper, and you don't have to worry about finding the napkin on which you sketched the new system design. Similar to this situation is the development of multimedia computers, all consumer electronics - music players, fax machines, pagers, audio magazines, or can be heard, can see, or unlimited digital transmission.
One aspect that is rarely noticed by wearable computing technology is its reality-enhancing technology: a seamless combination of virtual and real-world. Electronic information storage is very useful in situations where outside world information is covered. For example: the title of the museum exhibition shows that the name information is displayed on the surface (through face recognition technology), and the association chart of the current task is drawn.
Wearable technology features
The fuzzy definition of wearable technology refers to a computer that can be worn on the body like a clothing, not only comfortable but also easy to store and use. However, the definition of this "smart clothing" is unsatisfactory in the light of thinking. And more clearly defined is that wearable computing technology should have the following characteristics:
1, lightweight and ready to use
The most prominent feature of wearable technology is that it can be used while walking or other mobile modes. This wearable technology is similar to the difference between a desktop and a notebook.
2, hands-free use
Military and industrial wearable computers place special emphasis on hands free and value voice input and head-mounted displays or voice output. Other wearable technologies may also use a chord keyboard, dial input and joystick input to weaken the reliance on the user's hands.
3, sensor
In addition, for user input, a wearable product should have sensors that respond to the physical environment, which may include wireless communication, GPS, cameras, or microphones.
4, instant reminder
A wearable product should be able to convey information to the user even when it is not actively used. For example, if your computer wants you to know that you have received a new email from someone else, it should immediately pass it on to you.
5, always work
By default, the wearable device will always be on and working all the time, sensing and displaying. This is the opposite of the normal "personal digital assistant" based on pen-based input that is normally placed in the person's pocket and only activated when the work needs to be completed.
Trends in wearable technology
Invisible
According to Moore's Law, as electronic components become smaller and smaller, products are more efficient and more powerful. In other words, you can think of current wearables as stereo speakers on your wrist. Wearables and fashion will be inseparable and unbreakable.
personalise
Like wedding rings, people who wear them for a long time are very personal items. Therefore, unless the product has very important medical uses, such as hearing aids, there are very few wearable devices that consumers can wear all the time.Cuff has added personalized design to wearable technology. They put the technology into a series of jewellery so that users can choose which device to wear every day. In this way, wearable devices have become part of jewelry, and it is not only a technology accessory but also a fashion attitude.
efficiency
As wearable devices matured, other devices powered. Tommy Hilfiger officially introduced a new charging method that uses a fabric embedded in a solar cell to charge the device, as well as a kinetic-powered device, or even the idea of ​​using body heat to power the LED lights on the ring. Although these features are still some distance from commercialization, they will soon be seen to be applied to wearable devices.
accuracy
From the child's GPA to the adult's body mass index BMI, the numbers run through all aspects of our lives. As people's requirements for the accuracy of EQUIPMENT increase, the approximation is no longer able to meet the needs of consumers, and the number of steps is no longer satisfactory.
At present, we have not seen the industry regulations to set the relevant terms for manufacturers. In the future, the wearable product brand can give the accuracy of the equipment. Maybe you will see Jawbone's packaging on the guarantee that the gesture tracking accuracy is 99.5%. ".
Permission settings
Have you ever thought that advertisers will push ads to smart wristbands around the clock? As the advertising revenues of the TV and newspaper industries decrease, marketers are coveting this approach, and these new devices offer new opportunities for them to target potential customers. .
In order not to be the object of spam harassment, smart consumers will require the device's permission settings to stipulate that messages can be pushed. Imagine that a smart watch can be set up to allow only partners, children's schools, and mothers to push notification reminders to watches during work hours from Monday to Friday, which should save many annoying and unnecessary interruptions.
Perceived
In the movie "Her", artificial intelligence Samantha explained that she works like this: "Intuition. I grow up through the daily experience, self-improvement, this ability makes me become 'I'. I change all the time, just like You too."
Why are hundreds of motion trackers unable to learn to recognize more SPORTS, such as skipping ropes, potbells, or salsa dancing? People's interests are changing and evolving. Their wearable devices must also evolve and learn new things. A single pedometer on today's motion tracker won't exist for a long time.
Multi-point connection
The focus of the discussion on wearable technology will soon shift to whether the sensors carried on the device can measure data throughout the body in time. People wear an activity tracker and bring a smartphone in their wallet, both of which collect motion sensing data through internal accelerometers and gyroscopes.
Technicians are investigating how to get information about multiple sensors in the body at the same time, showing the user how his body moves and behaves through multiple devices and sensors.
Integrated
Imagine the following situation: holding something in my arms, the right hand is struggling to find the key in the pocket to open the door, but carelessly falling into the ground? Everyone will be like this: When you are full of debris in your arms, your heartbeat The signal is signaled to the smart lock on the door by the wearable device and automatically unlocked. When you pass through the living room and the wearable device on your wrist detects that your body temperature is above average, it will automatically signal the Nest thermostat to turn on the air conditioner. It also detects the body's moisture levels, and when you enter the kitchen, it triggers a smart refrigerator that automatically pours water for you.
Although it is still too early to predict which features or shapes will be welcomed in the future, wearable technology is still an area worth studying. Data processing components have never been as small as they are today, and they offer opportunities for medical advancement or annoying marketing nuisances. We are also moving closer to creating useful, usable, and satisfying products.
The tandem bicycle or twin is a form of bicycle (occasionally, a tricycle) designed to be ridden by more than one person. The termtandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. A bike with two riders side by side is called a sociable.
Patents related to tandem bicycles date from the late 1890s.In approximately 1898, Mikael Pedersen developed a two-rider tandem version of his Pedersen bicycle that weighed 24 pounds, and a four-rider, or "quad", that weighed 64 pounds. They were also used in the Second Anglo-Boer War. Tandem popularity began to decline after WWII until a revival started in the late sixties. In the UK The Tandem Club was founded in 1971, new tandems came on to the market from the French companies Lejeune and Gitane, and in the USA Bill McReady founded Santana Cycles in 1976. Modern technology has improved component and frame designs, and many tandems are as well-built as modern high-end road and off-road bikes.
Tandems can have more than 2 riders - tandem refers to the arrangement of the riders one behind the other rather than the number of riders. Bicycles for three, four, or five riders are referred to as "triples" or "triplets", "quads" or "quadruplets", and "quints" or "quintuplets" respectively. One such familiar to UK TV viewers was the "trandem" ridden by The Goodies. Originally a 2-man tandem with an extra "dummy" seat attached, a full 3-man version was built for them by Raleigh.
Some designs such as the DaVinci can allow independent pedaling through the use of multiple freewheels. [4] In another design, the rear rider steers and propels the rear wheel with pedals, and the front rider propels the front wheel with both hands and feet.
