hello everyone i'm bowen and i'm glad to introduce our work
new mod a modular haptic device with
localized pressure and thermal feedback
this work was done with professor
miesha's raw at perceptional engineering
lab at uc santa barbara
touch is a fundamental aspect of our ability to perceive and navigate in the
real world it is also a vital method for
communicating emotions
communicating emotions we have recently seen an increase in the
need for social interaction over video
conferencing or virtual reality
habitat feedback device can enhance
immersiveness in vr and support tactile
communication in different form or
digital interactions
digital interactions pure pressure haptics often use
pneumatic system with flexible ear bags
to bring pressure information to the
body
body
body thermal haptics are developed based on
perito devices fence hydraulic systems
to bring different temperatures
third module attached the peritectic
blocks to watch bands and the thermal
gloves use pelleted strips on the
fingers
fingers
fingers four fans are worn on the wrist to cool
down the skin in watchback tecto display
multi-model haptic feedback provides
both pressure and thermal sensations
patch is a hydraulic system that brings
compression and thermal feedback based
on the water temperature in a sleeve one
device
device
device thermal cares use pneumatic system
to produce pressure and hydraulic system
to produce thermal feedback both of the
system has limitations on providing
independent control on pressure and
thermal feedback simultaneously over
each pouch or airbag
thus we propose new mod a wearable modular haptic device that can be
simultaneously and independently present
pressure and thermal cues warm and cold
for different shapes shapes locations
and patterns
and patterns new mod can be easily configured into
sleeves armbands gloves leg wraps
headbands and other form factors enables
users to feel the temperature of touch
or other gestures over distance or
immersive haptic feedbacks in multiple
vr applications
vr applications here is a table of related research and
differences from new mod
feel free to check the full table in our
paper
paper
paper our system includes three main parts
one pneumatic hardware including air
source and solenoid valve manifolds to
provide fast inflation and deflation
two thermo-pneumatic
two thermo-pneumatic actuators that can be attached to
multiple form factors like a fabric base
three feedback control system including
a design control board an arduino
sensors
sensors
sensors firmware and a user interface
here's the detailed design of a thermal
pneumatic actuator from top to bottom
there is a thermistor to measure the
temperature
temperature of peltier device to provide thermal
feedback a silicon top cover and silicon
bottom cover for the air chamber a full
sensor to measure the
pressure applied on the skin and the
velcro tape to secure the actuator and
provide modularity
provide modularity here are the fabrication process
and fabric fabric sleeves
the figure on the left
shows the fabrication process
in a the silicon ear compartment is
fabricated by pouring mixed silicon
liquid into 3d printing modes then the
two parts and a tube are bonded using
silicone glue
silicone glue these shows the top view of the actuator
with a thermistor and a force sensor and
the c represents actuator without any
sensors
sensors
sensors this video shows different activations
from the actuator array
single activation
pattern activation
feel effects
here is an overview of the system and the user study setup
putting a new mod device on the forearm
so
we also designed different form factors all actuators can be attached to a
single sleeve showed in the previous
slides
slides
slides with the advantage of the compact
actuator design it is effortless to
attach one or more of them to multiple
parts of the body
for location like wrist arm chest
forehead
forehead
forehead calf or ankle actuators can be attached
to bands and worn on the body like
demonstrate in the right figure
there are two actuators on the chest
band and can be used to mimic being hit
on the chest
there's one actuator on each wristband
and one actuator on the forehead
we also did a user study on how users
recognize single bubble activations
patterns of activations and rating for
different level
different level of field effects using the sleeve form
factor we hope to present more details
about the study in the near future
we have used three applications to demonstrate how new mods can be worn and
used in vr remote touch and gaming
thank you so much for watching and please feel free to ask any questions
