This paper discusses the prospect of human-computer interaction. The paper proposes that the current prospect of human-computer interaction is controversial. Some people believe that people should focus on developing new metaphors and tools that enhance users ’abilities to directly manipulate objects. Others believe that directing effort toward developing interface agents that provide automation is much more important. So this paper later proposed a new system-outlook. This system is an email system, which creates a new interaction mode based on combining two ideas. The paper specifically describes the factors of the system, the realization ideas of each factor, and the realization principle and mathematical model of these factors are described in the second half of the paper. And these factors include: Value-added automation, Considering user’s goals, Considering user’s attention in the timing of services, Inferring ideal action, using dialog to resolve key uncertainties, Allowing invocation and termination, Minimizing the cost of poor guesses, Scoping precision of service to match uncertainty, variation in goals, Providing mechanisms for efficient agent−user collaboration to refine results, Employment socially appropriate behaviors for agent−user interaction, Maintaining working memory, Continuing to learn by observing.

Aiming at these factors and methods mentioned in this article, I would like to put forward my views on several of them.

  1. Continuing to learn by observing. I think this will be the inevitable development direction of human-computer interaction, and even the development direction of other computer science fields. Because people have different habits and education backgrounds, a universal interaction system, Not enough good for everyone. In a interaction, people are required to adapt to the system, but at the same time, the system should also learn human habits to serve people more conveniently.
  2. Maintaining working memory. I think this is came from the idea of computer caching. The introduction of the concept of caching in the system will undoubtedly serve people better. At the same time, I think there are two other benefits. 1. Recording the previous operations can become a training set for machine learning. Since we want the system to become more intelligent, and we hope the system can adapt to different people, so it is necessary to record the operations of each person. 2. This idea also inspired us to bring other successful functions that have been practiced and applied to other fields, it might bring some great impact.
  3. Most of the remaining factors are designed for human uncertainty. In my opinion, in the development of human-computer interaction, these factors can be merged into one factor, that is, human uncertainty. However, it can be seen from these factors that the difficulty of human-computer interaction is focused on human diversity and uncertainty, so overcoming this problem will directly affect the interaction experience.

questions:

1.For the two directions mentioned in the paper, which one do you think is more important, or the combination of the two?

2.Do you think it is urgent to add the concept of machine learning in human-computer interaction to better serve human beings.

3.Besides the factors of OutLook system mentioned in the paper, which factor do you think can be extended.
