BuddyClock: Sharing sleeping behavior within Social Network 
MOTIVATION & GOAL
Knowledge of remote activity, such as the sleeping status of a trusted friend or relative, can support socially-appropriate interaction.
Sleeping status information, naturally integrated as a peripheral augmentation of an alarm clock, can allow people to feel more connected with someone living remotely. Also it cam give subtle cues that friends can use to enhance their relationships
This study investigates how a simple augmentation of an alarm clock supports this sort of peripheral awareness in a small social network.
Through this study, I aimed to determine how shared, real-time sleeping status influences a small social network.
I predicted sharing sleeping status will:
- Impact everyday bedtime activities
- Give a better sense of connectedness among people in remote social networks
IMPLEMENTATION
The prototype is implemented using Python on a Nokia 770 Internet Tablet, using an 802.11b/g wireless connection to our remote buddy server. The BuddyClock screen shows status information for up to three other connected clocks. When the user changes the status, an icon on the display of others is changed to the corresponding status icon. Changes in remote user status are also signaled by a quiet tone to notify changes.
- Network-enabled
- Transmit current status and receive others
- On a Nokia 770 Internet Tablet, using an 802.11b/g wireless connection
USER INTERACTION
- Basic alarm clock functions such as alarm on/off and snooze
- Different icon on a BuddyClock display when status changes
- Beeping sound is played when icon is changed
EVALUATION & RESULTS
We structured a two-phase, within subjects evaluation.
- Phase 1: one-week control period
- Phase 2: a two-week experiment period
- Participants: two groups of three in the same social network
Results
1. Connectedness
All participants agreed that they felt more connected after having knowledge of others' sleeping patterns, saying that such information gave themselves more chances to think about others. In cases, it became a baseline for inter-personal activities later on.
2. Influence on Behavior
No statistically significant difference. We, then, noticed that there was a much wider variation in the sleeping and waking times after sharing sleeping status.
3. Privacy
Participants did not show much concern about privacy issues in sharing their sleeping behaviors with others
Sharing experience in cemetery visitors

PROBLEM SPACE
Cultural heritage space keeps a great amount of information about our
culture, art, history and its figures. To maximize experiencing in
visiting cultural heritage spaces, technology has been put for the
cultural heritage visitors. Electronic guidebook is a useful device to
provide visitors with auditory and visual information. However, the
current electronic guidebook has drawbacks; it is normally designed for
single-user usage, and thus using the device easily results in
hindering interaction between visitors and their companions. This
project aims to overcome the three drawbacks above, and give cultural
heritage visitors better experience along with their companions using
one"s own mobile phone.

Flora Electronica
PROJECT DESCRIPTION
Flora Electronica is an electronic/computational garden that acts as a real-time media performance space that manifests itself in both the physical and virtual worlds. The playful artificial garden provides a stage for spontaneous performances to unfold, which can create engaging experiences for both local and remote audiences.
The inhabitants of the artificial garden are reactive plants equipped with sensors and actuators, allowing them to respond to the visitors who pass through the space. The plants are clustered into three groups with different personalities: sociable plants, shy plants and bored plants. The garden invites interaction on the part of the visitors, who can entice the plants into enacting captivating robo-media performances. The plant clusters respond to visitors through light, sound and movement, which influences the overall emotional tone of the space.
DESIGN
The physical part of Flora Electronica is a robotic garden consisting of three large circular mounds, each containing three clusters of three plants. Each mound has a different personality type that determines how the plants react to visitors: sociable, shy or bored. Motion tracking sensors and microphones are integrated into the mound in front of each plant cluster. The plants grow, turn and glow in response to the movements and voices of the visitors who approach them, and also in response to remote events from visitors in the networked spaces (web applets and Second Life).
Each mound is 4 feet in diameter, with a central pole that supports a scrim overhead. The scrim is made from a translucent white fabric that allows colored light to shine through from an RGB LED lamp placed at the top of the pole. The lighting for each mound is designed to reflect its personality type, and changes with the level of plant activity.
INTERACTION DESIGN
Three Plant Personalities
- Shy
- Sociable
- Bored
- Interactor's Movement (photo sensors)
- Interactor's Voice (acoustic sensors)
- Remote changes to plant cluster's personality (Second Life interface)
- Plant Movement (leaning, stretching up, shiftingdown, gyrating)
- Plant LEDs (two colors, one indicates response to local stimulation, the other indicates remote changes to plant clusters personality)
- Overhead scrim lights (respond to local stimulation, indicate plant cluster's personality type, increase in intensity as plants enter gyrating mode)
- Sound (ambient low-key sound without stimulation, increases in intensity as plants enter gyrating mode)
- Static (no interactor in close proximity, no plant movements, low-level sound and lighting)
- Interaction (interactors engage with plants, moderate increases in sound and lighting)
- Gyrate (all plant clusters are stimulated, requires a group of interactors to activate all plant clusters; plants gyrate, sound and lighting most intense)
SOFTWARE DESIGN
A server-side application acts as a networked "brain" for the garden, and manages data communication between the three spaces. In the physical space, the garden consists of three mounds of plants that act/react via physical sensors and actuators, as well as sound and lights. A client program written in Java runs on a PC inside each mound, and communicates sensor data back and forth to the server in XML form. Data is also transmitted back and forth from the two virtual gardens, which are realized as Java-based web applets and in the Second Life virtual world. Video captured from the real-world garden is reflected in these remote spaces. The following diagram illustrates the architecture of the system.

PROBLEM SPACE
The nature of autism: a life-long developmental disability characterized by deficits of communication and social interaction
. Children with autism rarely share everyday things which are crucial to their development with their parents.
. Parents lean on information about children's activity performance from teachers or caregivers only.
. Difficulty keeping track of children's everyday activities
. Parents of children with ASD have tons of things to take care of.
PROJECT GOAL
1. To help parents track children's everyday school activities
- Parents can get information about children's activities regardless of time and place
2. To help parents prompt conversation with children
- Information of everyday activities children do at school can help parents to prompt conversation
- Both children and teachers do not have to learn a new method
3. Utilizing a schedule as an information transmitter

Street CATS
PROBLEM SPACE
Atlanta's populations is increasing rapidly and the increase in the number of automobiles is also proportional. Therefore, here in this project, we aim to make public transit in Atlanta more attractive, accessible and amusing, thereby increasing the usage of the public transportation.
FIELD RESEARCH
From our field interviews substantiated with survey data obtained from MARTA, we found three major reasons why people do not use MARTA; Inconvenience (32% & 6 participants), inaccessibility to transit (16%, 6), time inefficient (11%, 3). (Percentage in parentheses is from MARTA survey results and the number indicates the no. of our interview participants who felt the same). In another survey, MARTA found that 57% of the current users are using MARTA just because they do not own a car now.
