Vibrotactile Modulation in DentiXR
Back

DentiXR Haptic System

Vibrotactile Modulation

DentiXR changes both the frequency and amplitude of vibration according to the tooth layer being drilled, creating a distinct sensory cue for each change in resistance.

Layer-responsive cues Frequency modulation Amplitude modulation
Vibration Profile Layer detection active
Enamel Higher resistance
High frequency High amplitude
Dentin Softer tissue
Medium frequency High amplitude
Cavity Removal Lower resistance
Low frequency Low amplitude

Modulation Logic

How the vibration changes

DentiXR combines signal rate and strength to distinguish each drilling stage.

Signal rate

Frequency

Controls how rapidly the vibration repeats. Higher frequency feels faster; lower frequency feels slower.

Signal strength

Amplitude

Controls the strength of the vibration. Higher amplitude feels stronger; lower amplitude feels lighter.

Training Value

Clear tactile cues during practice

01

Distinct Layer Cues

Different signals mark changes between drilling stages.

02

Consistent Feedback

The same vibration mapping is used in every session.

03

Multisensory Practice

Tactile cues support the visual and auditory experience.
