Introduction of propaganda:
According to the Jowett in the Propaganda & persuasion, there are three types of propaganda based on the content, that is white propaganda, black propaganda, and gray propaganda[1].

1. White propaganda
   
   1. The information is correct but would have the focal point on specific aspects.
      
   2. To build credibility and positive impression with the audience for the future usefulness at some time in the future.
      
   3. Example: VOA (Voice of America) and Radio Moscow during peacetime.
      
   
   
2. Black propaganda
   
   1. The content of dissemination is lies, fabrications, and deceptions, which are often described as disinformation.
      
   2. The source is concealed or credited to a false authority
      
   3. Example: the political propaganda of Nazi government which twisted some of the facts of the Jews nation.
      
   
   
3. Gray propaganda
   
   1. It is a between state of white and black propaganda.
      
   2. The information is slightly distorted for a certain purpose.
      
   3. The source of gray propaganda may not be correctly identified and the accuracy is uncertain.
      
   4. Example: Companies would distort the statistics advertising the results that a product could not achieve.
      

In the age before industry age, the media and the effect of propaganda were limited. The effectiveness of propaganda during this period was mainly achieved by interpersonal dissemination.

In the age before the information age, the media of propaganda include radio, television, film, posters, and etc. The effectiveness of propaganda during this period was achieved through mass media distribution.

In the information age, propaganda increasingly relies on digital media and online platform, which allows information broader and more efficiently. The effectiveness of propaganda during this period is achieved by the speed of information dissemination and the accurate delivery of information. Technologies enable propaganda to be sent to target audience instantly and respectively.

In this era, our online behaviors are being surveilled and we are being analyzed through the networks. With the profiling software, our every click, shopping history or even eyes movements could be tracked. With Neurotechnologies and psychological analysis, our minds are being read and our online profile are being set up. With big datas, our datas are compared with datas from other users and our behaviors are being predicted. Network data acquirers know us better than we think. They want us to see what they think we would be eager to see and to hear what they think we would be eager to hear. According to the agenda setting theory put forward by Paul Lazarsfeld, although the information we perceived would not directly change our minds, it would have a great potential influence on them. Perception affects minds. Can it be considered as the invasion of individual will from general will and artificial intelligence?

Also, the development of the Internet has evolved a new business model. Most of the Internet service are free for consumers because of the massive scale of online advertising that partly result in the birth of pop-ups and spam, which are annoying forms of propaganda.

Definition of Blue propaganda
Blue represents futuristic technologies. I put forward a terminology of a new type of propaganda -- Blue Propaganda, that is a form of propaganda which is mandatory and relies on advanced media technologies.

The Speculative Scene Description:
It is a duty-free society (as like the free internet world in the last era) in which mandatory propaganda substitutes the role that duty once played. To some extent it is a free society that citizens would not have to pay for, as like the Internet system. From the perspective of propagandists, individuals, mules that create value and recreate value through consumptions, are considered to be able to do more contribution to the society by being leaded to behave and consume under the influence of propaganda than paying taxes.

Blue propaganda, a new type of propaganda referring to the mandatory propaganda based on highly advanced media technologies, has seeped into every corner of our lives.

• Visual blue propaganda: With the development of projection technology, our ambient air become the display. By tracking the position of target audiences' eyes, the pop-ups are projected in the front of eyes.
• Aural blue propaganda: The advanced directional speakers are able to send different sound propaganda to different target audiences' ears. Directional speakers are hidden everywhere, sending out sound propaganda like what mobile phone signal bases do now. Human ears are more vulnerable than human eyes because the hearing works 24/7 and it receives all sound information within the human hearing unconditionally.

New terminologies, information violence and thought invasion, are invented to protest the aggravating blue propaganda. From the perspective of the protestors, the blue propaganda go against the humanity and natural liberty. The freedom of perception is even more important than the freedom of speech. The blue propaganda would not change human minds directly but it would have a long term deep and profound influence on them, resulting in the loss of personal will to some extent. Protestors tried to eliminate the blue propaganda. They had three strategies: eliminating the source of the propaganda, cutting off the dissemination of the propaganda, and reframing the human sensory organs to block the propaganda.

1. Eliminating the source of the blue propaganda: The strategy failed. Propaganda is for the sake of the commercial or political profit of the propagandists. In a society valued interests and profits, it is impossible for them to give up such a powerful tool.
   


2. Cutting off the dissemination of the blue propaganda: The strategy failed. Freedom of expression remains to be one of the basic right of the modern society. Nobody has the right to prevent others from using the public space media to express their notions.
   


3. Reframing the human sensory organs to block the blue propaganda: though it was a reluctant choice, it was the only feasible strategy. The solution was to lock the sensory organs in a room, the door of which only open to the information that we want to get, which is similar to the spam blocker of the internet browser in the last era. From their perspective, freedom of perception can only exist in cages. A perception protection gear was designed.
   
   

Device design:

Concept 1: A helmet-like head isolation design
It is a overall isolation device for head, with huge sound collected on sides for collecting and then processing sound in the environment.

Self-questioning: the blue propaganda exists in daily life, so it is better for the anti-blue propaganda to be a milder design which should exists in daily life scenes rather than dramas.

Concept 2:
The inspiration of this iteration are glasses, which are essential things for many people and can be integrated into daily life scenes unobtrusively. The design is consisted of two aural propaganda filters on sides and a anti-eyes-positions-trackers on the front.

Each aural propaganda filter consists of a microphone, a speaker, a microprocessor, and a sound insulation layer. The sound insulation layer isolate human ears from the environment, making them can not perceive the sound in the outer environment. The microphone collects the sounds in the outer environment. The microprocessor transfers the sounds to electric signal, analyzes the signal using the fast Fourier transform (FFT), eliminate the part considered as “aural propaganda” using a trained machine learning model, and reproduce a sound without aural propaganda. The speaker plays the sound by the ear.

The anti-eyes-positions-tracker is a porous cover, which allows the users to see but prevented their eyes bu be seen by camera from a distance. The perception gear adopt the design language of electronic product design style of 1960s, which is the time before information era, when people were so fascinating with imagining the scenes of the technologies highly developed future.
