Creativity, dreams and mobile robots

by

Dennis Hong (RoMeLa, Virginia Tech) in his TedxNASA talk in September 2009 talked about biologically inspired tripedal robots, smart wall climber robots, cheap hydraulic arms, anthropomorphic football player humanoids, and even an unmemorably named artificial amoeba that is capable of chemically induced locomotion. His imagination of designing such autonomous mobile robots is not limited by the fact that very few of these exact motions exist in nature (i.e., take his 3-legged STriDER for example).

However for a cognitive psychologist, the really cool stuff is not these futuristic technological solutions, but Hong’s self-explanation about the source of his creative thinking when around 11:55 he asks himself a question: “Where do we come up with these ideas?”

He identified 5 sources of creativity:

  1. Dreams

Inspiration from one’s own dreams is what he calls out first. Every social scientist should be relieved that finally a real computer scientist dares to talk about the necessity of such soft human processes as dreams in the process of creative thinking. At nights when Hong goes to bed and about to fall asleep, he jots down on a paper notepad his wildest ideas (“..I scribble everything down and draw things before I go to bed”, 12:53). The next morning, he deciphers the ideas. Most days, there’s nothing on the page or nothing interesting, but occasionally he has something that he call a “Eureka moment”. When it happens, he logs these ideas carefully on his computer. What happens to these Eureka-ideas? Hong uses them to write RFPs (Request for Proposals) for his future research projects. In other words, he already has some answers for upcoming research questions and doesn’t have to wait for the inspirations to come.

2. Collaborations

Dreams on a group level could be called brainstorming sessions. Since individual ideas are not enough, Hong and his group have group brainstorming sessions. To facilitate discussion and make sure that students don’t feel intimidated, the golden rule is that nobody can criticize the other person’s ideas. All sorts of wacky ideas fly around, just like in one’s dreams. Once these ideas are recorded, people can decide which idea to pursue.

3. Education

Does school education really kill creativity? The fact is that to challenge the grand questions of science, you need tools. These tools are maths, physics, linear algebra, biology, etc. (neuroscience and philosophy are my additions to this list). While schools may not promote creativity per se, they provide the essential basis for students.

4. Work hard

The really good indicator of a creative and productive researcher labs – according to Hong – is that students and researchers are working on their ideas 3am in the morning. Not because they have to, but because they enjoy it.

5. Play hard

Finally, he admits that having lots of fun is the key. No need to explain this to anyone who has ever felt the joyous moment of a research Eureka-moment in their life before…

More people in a museum with Web 2.0

What makes a museum space good? For Nina Simon, the author of Museum 2.0 blog, the answer is simple: the more people use the exhibit spaces to interact with each other the better. Nina was giving an excellent talk recently at the BayCHI March meeting in the Palo Alto Research Center (PARC). She discussed issues of museum space design that engage visitors more by applying concepts from Web 2.0.

Museums are more and more looking for ways to break up with the image of being traditional and authoritative. In fact, most modern institutions shift towards a more participatory approach, where visitors are active part of the exhibits. Nina takes her examples from the social web (i.e., Facebook, Twitter, etc.) where the 3 core challenges are (1) participation inequality, (2) amateur content, and (3) limited tool for social interaction.

Social participation in a museum context refers to the use of the exhibited objects to facilitate interaction between the visitors. One simple example was The Art of Participation exhibition in the SFMOMA that opened in Winter 2008. What it did was to provide a social proxy (i.e., the use of different random objects) that allowed interaction. The key concept here is ‘scaffolding‘ or making the visitors feel safe about whatever they’re planning to do. Nina met a stranger at this exhibit, George, who went so far with participatory interaction that he took off his shirts for a photo (see half naked guy on her lecture slides with oranges in his hat).

Visitor feedback is another issue in museum spaces. A simple notebook where people can write their amateur thoughts is often turned into meaningless. The way to look at this problem for Nina is to take the Web 2.0 approach and allow the concept (i.e., notebook) to evolve into something better. In Worcester City Gallery and Museum, UK the weekly order of painting exhibits were determined by the votes of the visitors. It became so popular that people of the town queued every Saturday evening to see what the new order was. This is a great example of how to change ‘feedback 1.0′ into ‘feedback 2.0′

Asking a good question is another key to interaction. At the Ontario Science Centre, the turnstile was a voting mechanism to answer the simple question: “Would you go to Mars?” Needless to say, at the entrance, 2/3 of the visitors answer yes. It’s a personal (i.e., you), social (i.e., counting #) and fully participatory spatial design. As people learnt about the harsh physical conditions on Mars, and re-answered the question when exited the exhibition, 2/3 of the visitors didn’t anymore want to go to Mars. This is an objective and interactive way to assess visitors’ knowledge increase.

Exhibited objects themselves are perfect transitional spaces even for complete strangers to meet. Museum design needs to provide a scaffolding space that encourages social engagements. On the web, social profiling is a way to go about this. By giving visitors ‘social objects’ (e.g., a personality character badge — see Athena on Nina’s slide), it becomes acceptable to share experiences even if they don’t know each other. In social psychology, this is explained by the social identity theory (Tajfel & Turner, 1979). The key is giving social scaffolding to people that makes them feel comfortable. Human-Library.org project is another great example of how this can happen in a very simple but powerful way.

An audience question targeted the actionable implications of Nina’s work. She said that when she teams up with architects to design social museum spaces, she talks about how to create an exhibit space where people feel good together. Museums are just not optimal when there’s nobody inside, but they get better when a good deal of visitors are there. She paraphrased a quote by Tim O’Reilly saying that “web 2.0 is a software that gets better the more people use it.”

$60,000 for a life of happiness

by | 1 Comment

Clearly, the scientific community has taken an increasing interest in the research of happiness and well-being. In February 2010, the Nobel prize laureate, behavioural economist Daniel Kahneman gave a TEDTalk in this topic. The main argument of this talk was that happiness and well-being are indeed two very different notions.

Kahneman introduces two types of self in his talk: the experiencing self and the remembering self, and he demonstrates with different examples that these selves need to be analyzed quite differently. To understand the difference between the two, consider the following thought experiment. Think of your next dream vacation spot! Now, what if you were told that you won’t have any pictures or videos afterward and you were injected with an amnesic drug to forget all that happened to you during that vacation. Would you still choose the same vacation spot or would you change your choice? The example demonstrates a conflict between your experiencing self and remembering self.

However, it is unclear for me whether these mechanisms of our consciousness are functionally separate from one another or they are rather two sides of the same coin. It may well be that the experiencing self focuses on the ‘here-and-now’ with the acquisition, filtering and comprehension of the information; whereas the remembering self is concerned with the organization of ‘past’ events. But does this mean that one can exist without the other? Would this be the basis of amnesia? Wouldn’t it be more plausible to assume a single episodic memory that consolidates new information with existing self-knowledge?

Kahneman -the ultimate expert about human cognitive biases- also talks about the ‘happiness bias’. His example, is that people are happier in California not because of the good climate, but because they contrast themselves with living conditions elsewhere, for example in Ohio. Although Californians’ experiencing self might not be happier at all compared to Ohioans, people’s remembering self here in the West coast generally think that we are happier. Sort of a confirmation bias, whereby one interprets information in a way that confirms one’s preconceptions.

Finally, we hear in the lecture about a new Gallup study (couldn’t find the reference…does anyone have it?) that finds that in the US, the average income of $60,000 is a cut-off point for experiencing happiness. Above this income, the experienced levels of happiness is flat, but below this amount, the perception drops linearly. This shows that “money doesn’t buy you happiness, but the lack of money buys you misery”. For the life-evaluating remembering self, it’s a different story and the more money you had in your life the happier you remembered yourself.

POMI2020 retreat from a non-techsavvy perspective

by

Programmable Open Mobile Internet (POMI2020) is an interdisciplinary research program at Stanford University. It is part of a larger initiative called CleanSlate and funded by the NSF. The key players in POMI2020 are Stanford professors largely from the computer sciences, such as Guru Parulkar and from other auxiliary departments, such as the School of Education.

In today’s POMI retreat meeting in Palo Alto, CA the presentations were promising more interconnected and highly decentralized technological frameworks by 2020. Interestingly, however, the issues that advisors such as Bob Iannucci (formerly Nokia), Rick Rashid (founder of Microsoft Research) and Bill Raduchel (formerly AOL) brought up were fundamentally human-related questions, not so techsavvy ones.

In the first set of presentations, Monica Lam (Stanford Computer Science Dept.) and her team of graduate students presented an open-access database platform (SocialLite) that is being developed in order to collect and formalize social and personal information such as friendships, emails, and photos. This is an effort to overcome the limitations in FaceBook-type social networks that only provide “shallow friendships on a centralized datapark and does all this for profit”. Monica’s suggestion is to build more ad-hoc, mobile, multi-player apps that sit on decentralized personal cloud butlers (as opposed to a single public cloud) and communicates with each other via formalized data queries (e.g., FriedOfAFriend-queries; FOAF). The advisors, however, raised the issue that this effort comes down to the ages-old question of how to standardize representations digitally? Or as Bob Ianucci asked which one wins, the algorithm or the human eye? Until the researchers focus merely on computer-to-computer and not as much on computer-to-human communications, there is little hope for a revolution.

Our group from the School of Education, led by Paul Kim (CTO at Stanford) led the second set of presentations. The starting point was an analysis of the mobile industy (based on the evolution model by Fine, 1evolution of mobile market998). A recent survey of industry leaders and developers suggest that the currently expensive and integral mobile technologies will move into a cheaper and more modular market phase, inviting more mobile users (well exceeding the currently already 4 billion!) and trigger even greater interest in content development communities. This cheap and modular market will make mobile technologies increasingly available, especially in underdeveloped countries of the World, like Africa or parts of India. A project paper about this model-based prediction is on its way to publication soon.

Current in-progress educational applications were presented accordingly by Aiditi Goyal and Theresa Johnson (two grad students in our PomiED group): WeClick – an open-source, platform independent clicker app to be used in classrooms; Environmental Sensing Network (ESN) is a sensor-based science project utilizing design-based teaching methods. Questions from the audience were focusing on the costs and wireless communication issues. I was glad -but slightly disappointed at the same time- that the usability and educational aspects (two that I had some impact) did not gain any criticism.

After the first coffee break, Gabriel Takacs’ (Stanford) from the lab of Bernd Girod (Stanford Electrical Engineering; on the picture) presentation was about an automated image tracking & recognition algorithm that performed locally on a mobile phone. His algorithm is quicker and less data heavy than existing solutions which usually send full images over the network. Graduate students of the team demonstrated mobile applications that recognized foreign DVDs or labeled parts of a building. After identification, the system also linked the information with how much others in the person’s social network liked it. Neat! Check out their cool YouTube demo here. My association about this project was that they are doing what the human eye does — preprocess the information before it arrives to the visual cortex and makes it quick and easy for higher level cognition to match features.

The final presentation block of the morning session was by John Mitchel (Stanford Computer Science). He talked about http://courseware.stanford.edu, a work-in-progress collaborative and decentralized CMS. The idea is to work between institutions (e.g., Stanford & USD) and have open-access materials. What I’m not sure was how different this approach is to other systems, say Moodle. Bill Raduchel raised another issue about copyrights, which could be a real issue for open-access. Eric Conner presented a Mobile Courseware application that is an iPhone equivalent of our team’s weClick approach. Three major features: vote, Q&A and course-notes. I’m really looking forward to see this in action and potentially collaborate with John & Eric!

I wish I could have stayed for the afternoon session, as I really enjoyed interacting with these amazing professors and grad students, but I had to get back to San Francisco before the Sun went down.

‘Brown bag’ talk @Exploratorium

I will give a short talk at 1pm Oct/13/2009 (changed date&time!) in the Exploratorium, San Francisco, CA

Spatial Strategies: Routes of Exploration in Novel Environments

Why do some people like to follow the same routes over and over again while others are more curious about exploring their environment? When we enter an unfamiliar space, our cognitive system interacts with the surroundings by either acquiring new information or using existing representations. This interaction is influenced by heuristic spatial strategies, such as finding shortest distances or increasing our knowledge of the space. The behavioural outcome is the route that we take, however, it also determines the efficiency of later navigations. Frequent exploration patterns indicate a functional trade-off between spatial learning and the distance travelled. In this brown bag lunchtime presentation, I will demonstrate this trade-off and further investigate the effect of the spatial environment.
