Pros and consAUGMENTED REALITY

Three conditions: 1. Face to face

2. Projection display 3. Augmented reality

Pointing/picking gesture behaviors same in AR as FtF

Interface Aesthetics 04/02/07

[Billinghurst

AR slower than FtF

but ease of use similar to FtF

Effects of a wearable display on face-to-face communication

AUGMENTED REALITY

[McAtamney

& Parker, 2006]

Interface Aesthetics 04/02/07

Three conditions: 1. No wearable

2. Wearable present but inactive 3. Wearable present and active

AUGMENTED REALITY

[McAtamney

& Parker, 2006]

Interface Aesthetics 04/02/07

Presence of the HMD had no effect on the interaction, but the information displayed to the wearer did.

AUGMENTED REALITY

[McAtamney

& Parker, 2006]

Interface Aesthetics 04/02/07

The wearer was distracted by the information being presented to them on the head-set and was less able to give their attention to the conversation.

AUGMENTED REALITY

[McAtamney

& Parker, 2006]

Interface Aesthetics 04/02/07

The non-wearer appeared to notice the loss of attention to a lesser extent but felt that the wearer was not concentrating as much when the wearable display was switched on.

The more similar the patterns, the greater the visual interference.[Laramee

Course exhibitionINTERFACE AESTHETICS

Apply it to a topic of your research interest (e.g., tools for communication, learning/education, information visualization, etc.). Create a “mockup”

with paper, clay,

styrofoam

(or any other material) that embodies your original idea, concept, or design. Do not worry about the technical implementation, but be prepared to discuss “to whom, for what, how, and why”

your

design matters.

Homework for week 5INTERFACE AESTHETICS

Find examples of type in your environment.-

Successful type: text with a feeling or

tone that fits its purpose.-

Unsuccessful type: text with a feeling

or tone that does not fit its purpose.Take a clear, straight photo of each found type example and post the photos to the course blog.
