Lesson 11 - 10/01/2012

Intermediate Submission
Exercise 4: A Ball-inspired Interaction

Design Lab | Interactive Design | HIT

We began this exercise with at least five outlines per group for a ball-based interaction. We reduced the five interaction ideas to three, from which we will choose one to develop by the fast-approaching end of the semester.

This Saturday visitors to the Museum will have the opportunity to indicate their favorite interactions with a sticker to help us choose. So come along to vote and have your say.

Here come the balls...

Dina Rubanovitch Even-Paz, Omer Ben-Naim, David Kantor

The Kramer

Design Lab | Interactive Design | HIT

A board covered in white fabric positioned on an easel. A film is projected onto the board. The interaction is a game in which the player throws a ball onto the board, and the colors of the video change where the ball strikes.

Development of this project will focus on finding a more interesting projected object and response to the strike.

The critique focuses on the board being positioned on an easel, which is not connected to the interaction's gaming element.

Ripple Table

Design Lab | Interactive Design | HIT

A screen placed over a table, and balls falling onto it create colorful ripples that spread, as they do with stones thrown into a pool. The table not only registers the first strike, but also the ball's secondary bounces, and the effect obtained is beautiful.

Development of the project will include introducing an additional dimension, either graphic or sonic, and will address the colors of the balls themselves.

Spinning Head

The user sits in front of a ball onto which a live video image of his face is projected. Turning the ball makes the face turn together with the ball, creating a sense that the user is turning his own head.

Development of the interaction will include positioning the ball in a more accessible and intuitive way, and introducing an additional dimension, such as an additional rotation axis or addressing the rotation speed.

Converging Balls

Design Lab | Interactive Design | HIT

Lots of small balls projected onto a glass surface from below. On another surface the user places his hand, which is registered by a camera, and the balls converge in the equivalent location on the glass surface. The balls follow the user's hand movements on the screen and react to them.

Further development will enable incorporation of the projection and sensory surfaces, and will also address the shape of the user's hand rather than only the center of the mass.

Playing Ripples

Design Lab | Interactive Design | HIT

A ball rolling on a surface creates sounds on a two-dimensional scale according to its position. The interaction provides a new way of playing and attaches sonic validation to the ball's rolling.

Development of this interaction will create an environment in which use of the ball is more typical, such as a slope or the possibility of moving the surface, and will address bouncing the ball rather than only rolling it.

Pet Ball

Design Lab | Interactive Design | HIT

The ball contains a motor that makes it move slowly within an enclosed area. In reaction to picking it up from the surface the motor speeds up so that ball communicates virtual distress and its desire to return to the surface.

Development of the interaction will include accuracy of the details that are supposed to turn an inanimate ball into an ostensibly living creature in terms of both body and behavior.

Roni Rosen, Shahar Yaacoby, Shmulik Mauda

Musical Bouncing Surface

Design Lab | Interactive Design | HIT

A fabric surface designed for bouncing a basketball. Changes in the speed and strength of bouncing play different musical segments that combine with one another. There is also a possibility of recording and playing what's been bounced and played.

Development of the interaction will add variety to the notes played and make it easier for the bouncer-user to use.

Virtual Ball

A soccer player's shin guard connects the user's leg to the computer. Movements simulating a weak kick, a strong kick, and dribbling the ball trigger comic sound effects such as a windowpane shattering or a bomb exploding.

To develop the ball the group will increase the variety of movements and sounds and bring the sounds closer to the associative world of soccer.

Virtual Audience

Design Lab | Interactive Design | HIT

A ball placed on a stand that stabilizes it at floor height. An audience of almost life-size people is projected in front of the ball. Picking the ball up from the stand triggers a reaction in the people. When the ball is lifted slightly, the audience flinches slightly, but when the ball is kicked, they duck in alarm.

In the development of the interaction the details need to be more accurate: the people have to be life-size, and the reactions more varied.

Jenny Bahar, Osher Shukrun, Itay Kurgan, Shay Merci

Hot Air Balloon

Design Lab | Interactive Design | HIT

An aerial photograph is projected onto the floor, creating a sense of hovering in the air. Transferring a sandbag from the surface simulates adding weight to the balloon, and we draw closer to the ground. At each height the sideways movements change, just as the wind changes in a real balloon.

The group can now let go of the frame story and more accurately address the aspect of feelings. The more enveloping the experience becomes, the more enjoyable it will be.

Timid Balloons

Four balloons attached to a surface hover in the air. In reaction to a noise the balloons "get a fright" and are drawn toward the surface. Each balloon has a different sensitivity and they can get a fright together or separately.

In the development of the interaction the differences between the balloons need to be refined, and the composition of the whole system needs to be addressed.

Vox Populi

Taking into consideration the opinions of the instructors, the other students, the guests present during the submission, and the visitors to the Museum on Saturday, each group will choose one of the interactions it presented and develop it into the group's end-of-course project.

Come on Saturday and help us decide.

Until next time...
