HOW CAN THE SAW INTERACT FURTHER WITH THE USER

INTUITION THE SAWS FORM LANGUAGE CURRENTLY LACKS A COMMUNICATION WITH USER, ON WHERE TO PLACE

THE HAND AND THE DRAWBACK MOVEMENT

We were asked to define the Gardena value and form language by investigation the different products the compa-ny has to offer. We found the three definitions : innovative, playful and reliable.

USER TESTING

1. BLIND TEST

2. HARRIS PROFILE THE USERS WERE ASKED TO EVALUATE THE DIFFERENT VALUES OF>

WINNING MODEL: A+ grip

+ two hand grip+ stopper

+ fish belly

ANGLE OF BLADE

TESTED ANGLE 160 DEGREES

- Too big diameter- Too square in its shape (fish belly needs to be rounded)- Upper part is to square in its volume- Not intuitive in where to place the finger - Too flat of a volume in point A- Want more of a down angled blade

Changing the handle to a steep angle / so that wrist align to elbowRound the shapeWork carefully with volumes for gripDecrease diameter to 37 mmChange angle of blade
