to turn on/off in a
single press
Touch operations gives
user more premium feel

User Activity
Analysis
> the buttons were waterproof, but the tactile feeling was not preferred
> there was a small LED indication over each button, it was helpful but
not distinctly visible
> the positioning of the buttons were preferred as it was always in the
site of vision, and easy to operate while blending
> the touch operation was most preferred, as it felt premium and unique
> 30 sec timer was helpful as user did not have to think of when to
turn off the blender
> As light was within the button, not visible when touched
> Knob was very easy to use mode of operation
> Multiple speeds helped for better quality blending
> Press and rotate was found to be very difficult, while locking as
well as unlocking of the jar
> As soon as the jar was pressed the blender started, even before
it was locked, which was a risky task and was highlighted by all
the users

//User feedbacks+Problem solving
Uneven light distribution
Flexible pcb allowed itself to mount along the curvature, leading to even light distribution in each segment
Tactile Button failure
Due to space constraint tactile button feedback was not upto the mark as well as not a waterproof solution. hence capacitive touch was adapted which solved both the problems
Accidental touch led to
start of the blender
Delay of 150-200m secs was proposed
