Characteristics of Human receptors and effectors
Problems of Current Human machine interactions
Take advantages of human organs
Receptors: 10**9 bit/sec of information (Sight: 10**6 .. 10**8 bit/sec)
Effectors: 10**7 bit/sec of information
Humans World
Human has receptors (5 senses) and effectors with 100 billion neurons in total.
Eyes for seeing
Ears for hearing
Haptic
Tongue for tasting
Nasal for smelling
Audio organs for speaking
Hand/finger/body muscle motor systems
Commanding
(click, tap)
Text Input
(keyboard)
Pointing
(mouse, tap)
Voice become noises to
the others.
Voice doesn’t
keep privacy.
Seeing is 3D Current HMI
is 2D
Commanding
(click, tap)
Text Input

Pointing
(mouse, tap)
Those are very simple operations. Finger dexterity is far beyond current HMI.
Finger is slower than
seeing.
Finger is slower than
speaking.
Real interaction is multi-modal.
• E.g., you look ahead while driving a car by hand/foot, and you can speak while driving.
Current HMI is uni-modal.
• Seeing for machine output
• Finger manipulation for machine input
Multi-modal, parallel process
Wearable monitor system
Gaze tracking (3D) as a pointing
method
Silent speech
Muscle or gesture
language +Finger-ware
Haptic, BMI, …?
