1. An experience machine is used to stimulate one's brain and provide different life's experience for one while one just need to lie in a tank with electrodes attaching to one's brain. With the experience machine, one could encounter different matters and events which match to one's own interest and preference. Experience Machine is just a stimulation for people to believe that you are living in the reality.
2. Nozick tried to point out that rather than just to do what we want to do, how we develop ourselves and what are we in the process are more important. There's a line in the passage: 'Why should we be concerned only with how our time is filled, but not with what we are?'. It showed that what experience we had is not the matter instead what we have gained from the experience and how they contribute to our self-being.
3. In our point of view, the subjective experience completely determines the level of happiness of one. As we live based on the experience we obtained from everyday life, who we are was constructed by what we have gone through in our lives as well as how we dealt with the events. However, what we have to encounter may not be controlled by ourselves and they may bring various impacts to our lives. So whether the matter is positive or negative to us is determined by our own attitude. When one actively overcomes some difficulties, that may result in a positive, happy experience for him/her. Therefore, I believe the subjective experience determines the level of happiness of one

In order to facilitate the evaluation process, I recommend that you should clearly state which question you answer.

It seems that your discussions on question 2 don't catch the intention of Nozick's thought experiment. Nozick intend to reject that happiness is the only intrinsic consideration of human life. By the example of  Experience Machine, he may conclude that the subjective feeling of happiness, or felicity per se, cannot be determined  factor of meaning life or well-being of human life.
Further, it could argue that utilitarian reductionism, which reduces every other values to utility or certain kinds of subjective experience , is problematic.

i don't totally agree Pak Yee Verne Ser that the machine lead people to escape from the reality and search for the fake happiness. It is because experience machine is just a motivation for people to look for their happiness and consequence. Also, people can adjust their attitude even they can't get what they want finally. For me, experience machine is just a motivation to try to make people's preference to be possible.

I am so delighted that we have the same opinion on the question 1.
For the question 2, I agree with what Pak Tee Verne Ser said. Nozick wants to tell us that the happiness created by illusion is different with the real
happiness because as a human being, finding the truth is our nature.
For the question 3, I think we need to find the different level of happiness and we need to purse the high level of happiness and that is what my thought different with what I Mau Tsang said. It is necessary for me to find the different level of happiness.

I agree PAK YEE VERNE SER that the machine is only providing an illusion to people of what life is like, instead of what life is really is. Happiness and self-being needed to be searched and built by our own life experience. And one more key point is that I think people live to search for truth. But with the experience machine, everything is just a lie. Just like in the movie 'The Truman Show', the main character is living in a fake world and at the end he finally realized the lie and he could eventually finds out who he is.

Experience machine is used to simulate people's fantasy. The lives or experience can be created vividly to fulfill people's desire. If one's fantasized being a wizard or even characters from book, the machine could illustrate the experience as if it were real. The users are allowed to choose another experience when they are outside of the tank for 10 minutes or more. However, they would not acknowledge the tank (reality) when they were plugged in.

Nozick suggests one's happiness and well being should be created and experienced in real life instead of using the machine to escape from reality. He illustrates the machine gives a delusion of happiness. It prevents individual from being themselves and shaping their lives through real life experience.

Philosophers have been debated the nature of happiness for thousands of years, but scientists have discovered that happiness is mainly attributed by high life satisfaction, frequent positive feelings, and infrequent negative feeling. Above mentioned aspects are highly related with subjective experiences but still somehow objective factors like health condition, money, fame etc. affect one's level of happiness. So subjective experience is only one of the many factors.

Nozick offers a thought experiment to disprove the claim that the pursuit of pleasure and the avoidance of pain are the only factors that contribute to a person's well-being.

Experience machine is when people are plugged into the machine, they can experience anything they want, and are blissfully unaware that the experiences are not genuine. Such a machine could flawlessly simulate the experience of eating a delicious meal, writing a great novel, and falling in love. It could perfectly simulate every possible human experience, and the person plugged into the machine would believe their experiences to be genuine. However, in reality, the person's body would be floating in a tank with electrodes attached to their brain.
