Concepts created within the team.

Concept "Floor Pedal"

A sort of a pedal/mat would be placed on a floor. The user would step on it with his foot to change the slides back or forth.

CONS: The user would have to return to the same place to move the slides. Possible false triggers.

Concept "Finger Rings"

One or two rings on finger would act as triggers/buttons/switches.

CONS: Possibly false triggers.

Concept "Accelerometers"

The fingers or the hands would have accelerometers attached to them that would feed data into a piece of software. The software would monitor the movement, looking for a key motion that would signify that the user wants to move to the next/previous slide.

CONS: Accelerometers being bulky, interfering with signing.

Concept "Gloves"

A glove would have a switch on it that when pressed would move the slides forward.

CONS: False triggers. Sweaty hands.

Concept "Bands/Bracelet"

A bracelet with a forward and back button would be worn around the wrist. The bracelet would wirelessly communicate with a PowerPoint remote.

Concept "Lanyard"

A device would be worn around the neck.

CON: Could obstruct moving of hands during ASL signing. Remote must be located and oriented for actuation.

Concept "Dorothy Boots"

A trigger of some kind would be attached to the heels of the users shoes and when clicked three times together, would switch the slides forwards.

Concept "Elbow Trigger"

A trigger/switch/button would be attached to the users elbows/sides. When the user does the signs for "next" or "previous" his elbows are really close to the sides. He or she would tap the elbow against his or her side to trigger the slide change.

CONS: Variability in clothing.

Concept "Pager"

A belt with a wireless device would be attached to the user's waist. The device itself would have two buttons for "forward" and "back." The user upon his wish, would press the corresponding button to move the slides.

CONS: User has to stop signing.

Concept "Visual Recognition"

A camera watches the presenter and can recognize when the ASL sign for "Next Slide" or "Previous Slide" has been performed, and changes the powerpoint slide respectively.

CONS: Requires complex programming algorithms, has potential for many false triggers.
