A system comprising:

• a hardware platform comprising a computer processor, said hardware platform being a wrist-mountable wearable device;
• a touchscreen comprising a display having a display perimeter and a touch surface input mechanism having a touch surface perimeter, said touch surface perimeter defining a touch surface;
• a gesture input mechanism separate from and located proximate to said touch surface perimeter;
• said gesture input mechanism having a first sensor surface being mounted at a non-zero degree angle to said touch surface;
• said computer processor adapted to:
• receive a first gesture from said gesture input mechanism, said first gesture being one of a group composed of:
• a sliding gesture;
• and
• a tapping gesture;
• receive a first input comprising a first portion of a gesture from said touch surface input mechanism and a second input comprising a second portion of said gesture input mechanism;
• and
• determine a single gesture input from said first portion of said gesture and said second portion of said gesture.
