Mixed Reality

Mixture of virtual environment and real environment

To get augmented information which cannot be got in only one environment

Augmented Reality Real space is augmented by virtual infor.

Augmented Virtuality Virtual space is augmented by real infor.

What is brought by miniaturization of computer ?

Ability of computer 100 times – 1000 times in 10 years The same spec. in a smaller computer

“Miniaturization” = “quantitative transition” “Mobile” = “qualitative transition” Computer is spread over the space

Information occurs anywhere Information is processed at its position. The process is “natural”. It can be realized.

Information – oriented real space


Computer is spread over the space. Release of “zoning” of time and space What is “spatiotemporal zoning” ?

To keep “specialized space” and “scheduled time” for a purpose.

Phone call at “telephone box” Go to a factory and work


What is realized by “release of spatiotemporal zoning” ? If a space is connected to another space, Either of spaces should be a space which

has special information Classroom – field, laboratory, etc.

Keyword = mobile, wearable


Essence of miniaturization = integration of computer and human body

Computer, as a device which augments physical ability

“institutional” -> “personal” -> “intimate” by A.Kay


What is “intimate computer” ? A computer has a deep relationship with

individual information. The computer doesn’t work, even if other

person wants to use it. The computer is unified with an individual.


“Intimate” and “human interface” Man – machine interface 1st interface

Human body – artificial object (machine) 2nd interface

Surface between computer and network Surface between OS and application

“Intimate” means “interface is shifted to machine side” 1st interface is integrated into human body

network OS ・ device driver

application

1st interface2nd interface

Physical interfaceSystem - user More conceptual level interface

“Intimate” means interface is shifted to machine.1st interface is internalized into human body.


Conventional human interface

Organized by average valueTask management

Efficiency

・ human action is decomposed into basic action component・ standard working schedule is assigned.・ work and schedule simulation is possible.

Subdivision of work and shceduleMixture of semantics

Standardization is difficult.


Next generation human interface（ for intimate device ）

・ adaptation to diversity of individual・ no standardization on 1st interface・ standardization on 2nd interface

・ intimate device is a new uniform・ the uniform can be operated by “wearing it”・ there is network protocol outside the uniform


Institutional Personal Intimate Implant

Wearable computer

The famous professor, Dr. Masahiko Tsukamoto

・ Its metaphor is “cloth”・ When a man wears computer, he / she can join network society　（ When a man wears clothes, he / she can go out public society ）


Qualitative transition by wearable computer

Always ON Because of subdivision of period of use.

“Task unit” becomes very small. An interface which can be used with another work is

needed. Hands free interface

Sound interface One-hand operation keyboard (for example, mobile

phone) Unconscious interface

Unconscious input by GPS, RFID, etc.

Meaning of GPS interface

QuestionFrom here to Tokai U., how long does it take ?

If No “from here”

Wide retrieve area

10min Hon-atsugi

9hours Bangkok ?

1hour 10min shinjuku

4 hours Fuku

oka

4hours half Hokkaido

Unconscious input ofPosition by GPS

From here 30 min.

Despite no perceived inputNarrow retrieve area

From Here


The meaning of GPS interface Huge capacity information compression is realized For example, the difference between mobile phone

mail and conventional mail Mobile phone mail is usually shorter than

conventional mail. A new media develops a new culture, its

original style as time passes.


Wearable computer and AR

Use with GPS, gyro, ubiquitous computing, or environment-embedded computer. Information of an object in front of eyes is displayed

in real space Information of a building or encyclopedia

information such as view or flower Superimpose work manual on work area Life log Position information with GPS and RFID, for not

only outside but inside building

Information-oriented real space

Application of AR with GPS and Gyro

Measurement of position and direction of viewpoint

Computer has a database of the town

When use looks up at a building, the information of the building is displayed

Micro Display

GPS ForestField Science Education

User has PDA with GPS and Wi-Fi

User can know a position of user-own position (navigation). User can walk though no

road in woods User can get information

related to user’s position (contents). For example, user can learn

what tree it is.

New service of Rakuten travel （ 2009.12.2 ）・ User can see hotel information by iPhone, Air Tag ・ User can book a room directly from the Air Tag


Application of AR with GPS and RFID

Outside Use of GPS information

Inside Use of RFID and pedometer

Life Log : record of experience

User who wears wearable computer with camera, microphone and various sensors can record use-own experience unconsciously.

If 8 hours a day, the resolution is not so high, required capacity is 10Tbytes in 70 years.

What do you want to use it for ? A sense of experience can be analyzed

quantitatively The subjective experience is analyzed quantitatively. Multiple person can have the experience in common.

Body temperature, beat rate, air temperature, humidity are measured and recorded and the correlation among these experience.

Life Log : record of experience


experiment space for barrier free in Univ. of Tokyo

1300 active RFID Tags are embedded in floor of 1700 m2, in pitch of 1.2m

Each tag has own ID and sends information every 0.2 second

User with wearable computer and antenna for RFID tag can be detected in real time. The resolution is less than 1m. Hot spot is set every 5m Some hot spots have network camera and record

and analyze spatiotemporal information in real time

Navigation for deaf-blindness person Active studded paving block to aid

the blind Not only user information but

environment information is also obtained in real time.

Leading path is decided every 100ms.

The decided path is transmitted to user by the special device.

a plan of area-exhibition in the 2005 World Exposition

A plan of exhibition system which doesn’t use “building”

The real space (natural space) is used for exhibition space for ecology

User can access information by using wearable computer and HMD.

It couldn’t be realized due to the cost of devices, quality of information and the sense of incompatibility about “wearing anything”
