    If Dropbox were to give users more insight into how they are utilizing their accounts and give them an estimate of when they will run out of space, users would be more likely to use their accounts more when they buy more space or engage in other space-gaining activities like referring friends.
    Action:

    the estimate. With even just 0.5% of Dropbox's users, that would be 1.5M users as of this writing.

    Whether predictions correctly predict usage patterns for both those who are told the estimate and those who are not told (because simply seeing the estimate can cause users to change their usage pattern). If we show users these messages, then they should be roughly accurate.

    deleting files.
    Which messaging had the greatest positive affect on users: graph, estimation, or both? (Positive affect being started earlier getting more space when needed and more fully utilizing their Dropbox space.)

    This visually tells the user what percentage of space they have used and what is remaining, helping them predict when they need to get more space. It is said that this bar, which was an intern's project, paid for Dropbox's entire internship program up to that point and then some.

    Metrics:
    There are several key things to measure about the results of this experiment:
    Percentage of usersUsers actions before and after seeing the graph and/or estimate.
    Users actions
    who reachnever see the graph and/or estimate
    Time users begin engaging in space-gaining activities before
    their limitaccount is full (with and buy more space
    Percentage
    without the messages).
    Average level of engagement
    of users who reach their limitwith and simply delete files to make room
    Percentage
    without messages. (Number of usersfiles uploaded/shared and other activity)
    Whether predictions correctly predict usage patterns for both those
    who seeare told the messageestimate and those who are not told (because simply seeing the estimate can cause users to change their regular usage patterns at all (<explain how to measure regular usage patterns>)
    Percentage of predictions that correctly predict
    pattern). If we show users these messages, then they should be roughly accurate.
    Evaluation:
    See howwhether users respond tochange their usage patterns after seeing the messagemessages - do

    or both? Also see when users respond most toAre they more active and use more of the message being present - when the message says "within the week" vs "within the month" vs "within the next 3 months".space they own or do they become more frugal, decreasing usage or even deleting files.

    Measure
    As it is a website, we can employ the typical measures of website success with Google Analytics and surveys, such as:
    How many active users / unique page views per day
    Survey to users for feelings before and after on an issue. Did this website change your view point? Do you now understand the different viewpoints from which you can see this problem? Does this make your research life easier?

    Evaluation and Challenges
    At a larger scale, the goal of this project is to try to foster understanding between opposite corners of the world. As such, there is no quantitative measure for the success of this solution other than finally seeing world peace. At a smaller scale, this product aims to be of tremendous use to scholars to understand the complexities in our increasingly interconnected world. As an evaluation of this project overall, if this project provides utility to some subset of people, then it is considered a success.

    Video censor (facing the driver). This will detect how often the driver is distracted from looking at the road, and how quickly they return to paying attention after distractions.
    GPS: where does the driver and how risky are those areas
    Metrics:
    Insurance companies can create a formula to calculate the overall driving performance, and by using the data they collect by those sensors they can evaluate each individual drivers by computing their total safety scores.
    Then we compare the safety scores with the number of accidents of individual users in a period (can be a year), and so on we can figure out the exact insurance discount with different safety scores
    Evaluation
    see if the predicted number of accidents in a year matches the real number of accidents a driver occurs (if the formula is correct)
    Compute the extra discount for safety drivers and the extra fine collected from reckless drivers. (compare the gains from this policy and it loss, it in general we lose money, we can adjust discount rate and fine rate )
    Do a survey to see if all the users love this policy or not.

    LIMITATIONS
    Privacy: many individuals highly value their privacy, and would not be willing to install these devices in their cars. We will address this concern by letting clients decide to use the black box feature or to decline it. This way, only those who do not feel that the black box is intrusive would be affected by the data change.

    As with any experiment, there are challenges. In particular, the data processing and sentiment analysis to generate succinct 200 character summary blurbs is one of the largest perceived challenges, especially with the added factor of language differences, and even within the same language, regional differences in phrase usage. Disregarding the complexities of linguistic analysis, how will the visualization tool handle discordant opinions within the same geographical region? Currently, the idea is to provide a different summary for each different opinion. But what if, within a region, there are many different opinions such that it becomes psychologically distasteful and/or impossible to go through them all? This is especially applicable at the first search result, with the map of simply continents. One cannot expect the whole of Europe to only contain 5 different opinions about ISIS, for example. And further, what is considered an opinion? In a world of so much information, how do you generalize meaning from some assembly of words, and then report the subjective opinions of each article accurately in a relatively quick run time?

    Regarding the issue of too many discordant opinions, we can employ UI tricks (such as hiding some search results within a "next" button) to make the result more visually accessible.
