The most expensive, best and top piano?
There must be absolute, objective and scientific standards.
It is required to be able to play in space.
The simplest and most clear assessment criteria:
The manufacturing can independently adjust the tactile sensation of each key and the comprehensive mechanical parameters of the struck strings in microgravity, and can be set by a computer, and manual tuning is not needed;
It can produce tone sandhi, extended tone, vibrato and glide of mechanical actions, which has the complete dynamic characteristics of the traditional piano;
The manufacturing can ensure accuracy and accuracy in the space environment.
the mechanical characteristics of the traditional mechanical piano are not ideal and perfect! ! ! ! The traditional piano feels sluggish and sticky.
make pianos that can work normally under the conditions of bumps and shock vibration,
make force feedback keyboards,
make optical fiber transmission pianos, electric drive pianos, real-time contact with the force feedback keyboards in outer space, and a large-scale system in which the string striking mechanism and the sounding board are separated from the sky and integrated with the sky in aircraft, ships, cars, aircraft carriers and submarines.
playing for international conferences, opera houses, concerts and the Olympic Games.
The most interesting piano games are:
astronauts,
on the space station,
playing the force feedback keyboard,
watching the movement of the mechanism that strikes the strings on the ground,
listening to the wonderful music of the * * * sounding board,
and playing the piano by the astronauts floating in the air in space.
You
watch, watch and watch the dynamic movement of the strings being struck on the plane,
and share the wonderful chords of the * * * castanets.
In the submarine, you played the piano concerto with the astronauts through the force feedback mechanism.
Whether the performance of the piano is the best,
Whether the quality is too hard,
There must be strict assessment standards,
One of the assessment methods,
is to be able to play normally in a bumpy car.
Further assessment,
that is, in weightlessness environment,
not only can it be played normally,
but also the touch of the keyboard should be completely consistent with the piano playing on the static ground, and further, each key should be independently adjustable and more advanced.
The goal of human struggle and the long-term pursuit,
is to play the traditional piano with mechanical transmission in the weightless environment and vacuum environment in outer space.
Our Gada,
creatively carried out interesting military training, entertaining military training and scientific procession,
adopted various companies, classes and echelons,
randomly mixed into groups,
fell in love at first sight, wishful thinking (wrong usage) and wishful thinking according to their respective pairs.
Because everyone has wearable computer equipment and communication equipment,
under the unified dispatch of the battlefield automatic command and control system,
in strict formation,
complex formation transformation is carried out,
surpassing the national teams in the Red Square military parade,
leading the latest military scientific and technological progress,
showing the Chinese people's comprehensive national defense. ! ! ! !
Even if you enter a strange venue or pass through a rugged area,
you don't need to underline the ground.
When you drill in the queue for the first time, you can arrange a uniform formation for the first time, ensuring a strict dynamic phalanx during the procession.
The traditional idea is that military training is to cultivate group consciousness, self-discipline consciousness, forbidding consciousness and exercise people's willpower. These are all missing by our young people now.
We collectively wear VR glasses and AR glasses for formation change training.
The stragglers, grass-roots teams, street hooligans, stragglers and beaten soldiers are even more neat and tough than the regular army who has been trained professionally for a long time! ! ! ! ! ! !
You don't need to concentrate and practice together, you will be uniform when you walk on the stage for the first time. If you want to change dynamically, you can quickly combine them into various continuously changing animated graphics and complex glyphs.
Play some tricks, such as:
Every time the head and guests give an instruction, they will automatically recognize the voice immediately, and immediately change the corresponding human subtitles.
This is the latest creation of group gymnastics. < ! ! !
When the instructor gives a slogan and an order at random,
the teams are immediately grouped into corresponding human subtitles! ! !
an unforgettable national defense military science and technology education! ! ! ! ! ! ! !
wonderful, touching and shocking! !
We have cultivated a strong sense of national pride and a serious sense of historical responsibility since childhood.
We have exercised our strong physique, which makes us simple, healthy, bright, with lofty ideals and persistent dedication.
Instructors have developed the most advanced national defense military games in the world,
Virtual reality science and technology have been applied to military training subjects, and
You have been inspired to devote yourself passionately to military training.
It glows with your overwhelming youthful vitality,
It attracts you to enjoy this and that, and you are addicted to it. You are always happy, happy and forget to return, absorbed, obsessed and obsessed,
It tempts those students who are afraid of hardship and fatigue and have no strong will, and gradually cultivates their strong fighting spirit and will.
Students, onlookers, spectators, teachers and students, relatives, family members and citizens with different classes, grades, ages, genders, physiques and walking habits can join, insert and participate at any time.
Tourists from different countries with different colors, races, nationalities and costumes can participate impromptu and immediately integrate into virtual reality group gymnastics.
Under the overall scheduling of the commander and the computer automatically generating the pattern style,
with the active coordination and cooperation of the participants, the students undergoing review and the soldiers engaged in military training,
the overall formation is not affected and continues to be in a predetermined and continuous pattern change.
random arrangement, random combination, changing each other's positions at any time, and random selection of surrounding partners,
but it does not affect the overall changing effect of the dynamic and continuous changing graphics.
It has aroused the patriotic enthusiasm of teachers, students and parents, and strengthened the cohesion of loyalty to the motherland.
In the national college entrance examination in p>216, the essay topic of college entrance examination in Zhejiang Province is related to virtual reality. In this regard, we will discuss it with the combination of parade training in primary and secondary schools, group gymnastics, cultural and sports performances, military parade and square dance.
I hope to realize my original design more than 2 years ago in the yue soldier style and cultural performance of tamgc in 219.
The requirements of these activities are very similar. When groups are grouped and moved in groups, they should be able to measure the spatial position and accurate movement track of everyone in the field at every moment in real time, continuously and without contact. The measured data will be automatically
edited and processed in the form of secondary images, and the measured dynamic images will be forwarded to the wearable devices of each player in the venue in the form of immediate feedback. Another task of the measurement and control system is to calculate according to the pre-specified parameters for the overall movement of the team. For example, < P >, a queue of students is required to arrive at the geographical indication specified on the east side of the president's podium at what absolute time, and then the queue of students leaves a geographical indication on the west side of the podium at the specified absolute time. In this way, a continuous < P >, animated and virtual scene reflecting the traveling speed is calculated, and each frame of image in this animated scene includes the ideal geographical position of each student. This scene is also immediately forwarded to every student in the queue.
each student in the queue can observe two superimposed images in his wearable device at the same time, and the two images are distinguished by different colors. Every student in the queue immediately knows how to correct his position in the movement, which < P > includes the deviation change of walking direction, the adjustment of gait and the change of walking speed.
Therefore, this system establishes the cooperation and tacit understanding between each student in the queue.
For collective dance performances and sports, as well as physical details, it is necessary to have a body posture measurement system and an ideal body posture command system.
This system can command the group gymnastics performance in real time, and realize the flow, blooming, gathering, diffusion, deformation, distortion, reduction, amplification and other performance effects of group graphics.
This is totally impossible for traditional, inherited, ancient and handed down from generation to generation training methods. In the past, training methods, in order to construct ordinary graphic changes, had to practice hot summer in summer and cold winter in winter, and had long-term professional training and drills, and repeated rehearsals < P >, which occupied students' precious youth time. Moreover, the training of these graphic transformations has no "meaning of sustainable development", but only belongs to a report performance that will not be repeated.
and the most outstanding innovative significance of this method is that it can be a VIP or a customer who pays the sponsorship fee. A poem, a lyric, an impromptu performance by the band, an impromptu change in the mood and dance posture of the lead dancer, and a cadence of recitation will immediately generate a matching
command figure, which will be immediately realized in a vast venue.
For impromptu conversations between guests and hosts, verbal battles between actors, and lengthy declarations of love, the formation is changed continuously.
the same system can also be used for the cluster formation performance of unmanned aerial vehicles in the air.
This is a milestone in the revolution of the performing arts. These effects have been explained in more detail in the "guided fireworks" and "guided fireworks" that have been published on the Internet (both my humble works).
The author of this paper put forward the design of music conductor in 198, and it was only in 1995 that Japan implemented it. The author of this paper started the work of "force feedback keyboard" before the reform and opening up, and the above contents are closely related.
The neatness of formation is relative, and the irregularity of formation is absolute.
In today's era, AR, VR, MR glasses and helmets will also be used in drills and square dances. This is black technology.
The public has seen many trajectory parameters displayed on the screen of remote control of unmanned aerial vehicles and in the screen of space launch control hall. For the above group performances, each performer has his own independent set of motion trajectory parameters, and another set of motion parameters related to the overall movement < P >, which shows that this system is not "pediatrics".
The motion trajectory should be represented by a variety of data. In addition to the absolute geographical coordinates of the current moment, there must be previous coordinate parameters, which are related to each other, so as to represent the "motion trajectory". Therefore, the "trajectory" includes the direction and speed of movement.
For this kind of open-air and large-area place, it is impossible to lay sensors on the ground to detect the actor's motion trajectory; Ultrasonic attenuation in air is fast and its propagation distance is short. The resolution of microwave radar is low here, and the terahertz radar with high precision is under development, < P > at present, it can't meet the requirements of large-scale field detection; Radio tag, differential GPS and radio frequency ranging system are not practical; The scanning speed of lidar is low; Portable inertial instrument system with high acceleration sensitivity (high precision) and low drift has not been made in China. The image taken by satellite < P > is limited by resolution, transmission delay and long time for data analysis and arrangement. Shooting in the air by unmanned aerial vehicle requires accurate measurement of the trajectory of the unmanned aerial vehicle first, and then the spatial attitude of the camera carried by the unmanned aerial vehicle is measured. < P > The whole data processing process is very huge. Of course, if you have a good knowledge of mathematics, you can directly calculate the absolute geographical coordinates of all the targets of the entire phalanx and motorcade under review by fixing the object signs on both sides of the image; Only the visible camera is suitable, effective, useful and practical.
of course, in the environment of rain, snow and smog, the ability of visible light shooting system also drops sharply.
in the military field of enemy-enemy confrontation, it is more difficult to collect space targets on the battlefield.
It is expected that in hostile and concealed battlefields, the measurement of battlefield environment, such as battlefield topography, enemy's position, military layout of both sides, etc., can be completed at high speed and in real time, and the terrain can be surveyed effectively and quickly, which can be quickly deployed on the battlefield with other on-site situation measurement systems to provide tactical support and individual command support for
combat troops. Take the initiative to advance the decision-making time of fighting the enemy and shorten the passive decision-making time of the opponent.
A new function of this system is that performers can immediately see the overall performance effect and appreciate their artistic achievements from the wearable display device. Of course, in order to improve the level of performance, it is usually to choose to show the local scene where the individual is.
This set of equipment can also be used to direct the "cheerleading" performances interspersed during the break of the ball game; You can also coordinate the "flash" display; You can also schedule courtship, confession, marriage proposal and other publicity activities under the student dormitory. Lighting candles and setting off fireworks are bound to be a devastating attack on the property and security. It is necessary to show the huge lineup unexpectedly, suddenly, lightning-fast, and instantly to have an unforgettable shock. It can also help commercial promotion performances on public occasions, invite the audience to participate in interaction and experience passionately < P >; You can also temporarily pull people from the street to piece together the stage play of the Caotai team (if you invite them, you will go away and call them), and the effect can be called the professional performance team trained in the traditional way for a long time; It can also be used for inspirational group activities; It can also be used to train employees' cohesion
; It can also promote students' unity, cooperation and coordination; Science popularization and national defense military education can also be carried out; It can also be used for military training of students who have just entered the school (entertaining themselves, organizing themselves, not hiring instructors, and avoiding love between instructors and trainees) < P >; It can also be used for flirting and fun between lovers; Can be used for hide-and-seek games between parents and children; Can be used to guess, do you know where I am? It can also be used for TV programs and mass art, sports and entertainment activities to compete for competition programs; You can also use
in "field" confrontation activities; It can also be used for search training; Can also be used for jigsaw puzzle entertainment activities; It can also direct exploration activities in unknown areas; You can also help
