Brain-Computer Interface (BCI) is a direct communication medium between a brain and an external device. The thoughts of a person could directly be converted to actions without a slightest muscle movement. It could be invasive or non-invasive type. The first one uses direct implantation of electrode in brain while the second one uses electrodes mounted on the scalp. The electrodes measures the electrical or magnetic field or blood flow changes due to activity of neurons. Electroencephalography or Magnetoencephalography or functional magnetic resonance imaging could be used for this purpose.
It is most beneficial to persons with locked-in syndrome or total paralyses for communicating the thoughts with their environment.
The complication exist to in capturing the activities of millions of neurons in brain and also the pattern of data varies not only from person to person but also from day to day and even event to event.
An interesting game developed using this BCI technology is 'Mind Ball' preceded by an earlier version known as 'Brain Ball'.

INTIMATE GAME CONTROLLERS
Link: http://itp.nyu.edu/sigs/wearables/intimate-game-controllers, http://www.jennylc.com/intimate_controllers/
Video: http://www.youtube.com/watch?v=f2ocGIQL55s
It’s a game that you’re playing in couple. Like an erotic game, where you have to touch your partner’s body (in precise area) to win. The man is wearing a boxer, and the girl is wearing a bra.
Technology:
The technology used here is has to be wearable. The sensors are FSRs - force sensing resistors, they detect where you touched your partner. The Atmel chips is the microcontroller used to interface the sensors with the computer.
And off course there are clothes: a bra, a boxer.
Motivation and strengths:
It raises the question of how game can change our interactions, how it can bring husband game players to their wives.
Innovative controversial, pushing the limits in game controllers.
“Excuse” for intimacy and way to relax.
Weaknesses
The position of the sensors enables only one game position, and it is not so equal because the men is behind the girl.
The game is a little bit basic, so it can be boring so fast.
How would we improve it
Put different kind of sensors for different kinds of sensual experiences: more sensitive – gentle touch, less sensitive for harder touch. Type of sensors directs the interaction and the experience.
Use the game for cooperative rather competitive game. Weird intimacy should go with collaboration.
It can be fun to put a Multiplayer mode. Moreover this game is not designed for gay people.
Kickbee
Original design by Corey Lane Menscher
Kickbee is a wearable device that can sense the baby kicking in the mother’s womb and share that information with others. Each time the baby kicks, the kicks is being sensed and recorded through a belt that future mother wears, and then information about that is being sent to a twitter. In this way father and other people that are not physically close could still share the information about baby’s activity during the pregnancy and in this way try to share the experience of pregnancy.
Check out the video at http://kickbee.net/.
Technology
Kickbee uses the advantages of a wearable technology. Piezoo sensors that can sense small movements underneath it are placed inside an elastic fabric. Every time the movement is detected, after a baby kick, the info is being sent wirelessly through a Bluetooth to a Java application on computer near buy and then being posted to twitter through Twitter API.
Motivation & Strengths
We liked this device because it aims to enable parents to share the time of pregnancy and experience and exciting of expecting a child. We also liked that it is family oriented which is an area where we don’t see so many products. We find Kickbee to be a smart way of using a technology to assist and enrich everyday live, and bridge the limitations of physical separation.
Weaknesess
The weakness that comes from the technology used is that the pregnant woman that uses the belt has to be still. Otherwise her regular movements would be interpreted as baby kicks. Also in the current implementation, the message about baby kick could be sent too often and thus bore the user, with the same kind of repetitive information.
Furthermore the computer has to be in the close proximity to the Kickbee belt which limits the situations and the environment in which it could be used.
How would we improve it
Primarily, if the information is being shown on a computer or through a message, we would like to see a visualization of data, throughout the period. This would solve the problem of data sometimes being sent to often. Instead we could see how active the baby was that day: for example “Your baby was super active today” or “Your baby is a bit sleepy today.”
But more importantly we would like to have the feedback shown in another type of way: through a physical experience, rather than text message. The father could be waring similar belt, with sensors, which would trigger vibrations in places and with intensity in which the original kick was noticed. This would require a bit of change of technology in the original belt, because it would need to record the position as well. But we believe that in this way the experience of the pregnancy and baby kicks would be transferred and shared in the more appropriate way. For example, this approach of recording physical activity and recreating was used in Funambrella http://www.youtube.com/watch?v=XlFmwxYisP8.
- Visualization of the data received
- The feedback is expressed in the same manner as it was received – as vibration or touch, in the look like belt that daddy would be wearing. In that way they would be really sharing the physical experience.

Exploring Information Spaces by Using Tangible Magic Lenses in a Tabletop Environment
Upplagd av Patrik BIt is just like a special eye to look at the data world!
Technical setup:
- Camera: detect the paper
- Projector: project both on the table and the paper
The device is easy to use. By moving a tracked sheet of paper, the user can explore more information on the tabletop display. Users don’t even have to use fingers to touch the paper. They can control the paper by their natural movement.
It provides a new method of exploring the inside world. Traditionally, we use pictures, models, computer models to let people know what it looks like inside the things. This design makes it possible to see any cut-plane slice of the thing conveniently.
It can be apply to explosion or education. It is a promising device!
Motivation: To solve the challenge of exploring large information spaces on interactive surfaces.
RayMatic – Emetional aspect in hci
In the RayMatic project they build an thermostat display that looks like a frame with a human face that’s react emotional on temperatures in the room with facial expressions and gestures instead of the classic numeric displays. If it´s warm he will fanning himself, if you touch the person on the shoulder you get the setting mode.
It´s interesting to use the emotional feelings in human computer interaction.
