Teleassistance in Accessible Shopping for the BlindVladimir Kulyukin
In this paper, we present TeleShop, the teleassistance
module of ShopMobile 2, our mobile accessible shopping system for visually impaired (VI) and blind individuals
that we have been developing for the past several
years. TeleShop enables its users to obtain help from remote
sighted guides by transmitting images and voice from their
smartphones to the guides’ computers or phones. We have
successfully tested TeleShop in a laboratory study in which
a married couple (a blind husband and a sighted wife) used
it to retrieve grocery products and read nutrition facts from
product packages.
The Blind Leading the Blind: Toward Collaborative Online Route Information Ma...Vladimir Kulyukin
The long-term objective of our project is to discover the fundamental
principles underlying the collaborative production,
sharing, and management of route information by travelers
with visual impairments. The specific research hypothesis is
two-fold: 1) people with varied levels of vision loss and orientation
and mobility (O&M) skills will be able to form online
social networks that collaboratively manage large route
information collections for different geographic areas, and 2)
members of such networks will be able to successfully travel
through a variety of previously unknown indoor and outdoor
environments of varied complexity when provided with online
verbal route directions referencing landmarks and path
integration information salient to their particular vision and
skill level. In this paper, we report on the initial stage of our
project: an online survey whose objectives are to collect samples
of route descriptions from travelers with visual impairments
and to do the initial profiling of the target population.
The data collected so far provide valuable insights into what
travelers with visual impairments need to know about their
environments in order to travel independently and how they
may communicate that information to their fellow travelers in
the future.

This is a brief comparison of PermaMatrix vs. topsoil, mulch and compost. By hydraulically applying this organic biotic soil amendment containing Biochar, you will not only cut costs, but also cut pollution and create a sustainable environment for plants to thrive.
Robot-Assisted Shopping for the Blind: Issues in Spatial Cognition and Produc...Vladimir Kulyukin
Research on spatial cognition and blind
navigation suggests that a device aimed at helping blind people
to shop independently should provide the shopper with
effective interfaces to the locomotor and haptic spaces of the
supermarket. In this article, we argue that robots can act as
effective interfaces to haptic and locomotor spaces in modern
supermarkets.We also present the design and evaluation
of three product selection modalities—browsing, typing and
speech, which allow the blind shopper to select the desired
product from a repository of thousands of products.
RFID in Robot-Assisted Indoor Navigation for the Visually ImpairedVladimir Kulyukin
We describe how Radio Frequency Identification
(RFID) can be used in robot-assisted indoor navigation for
the visually impaired. We present a robotic guide for the
visually impaired that was deployed and tested both with
and without visually impaired participants in two indoor
environments. We describe how we modified the standard
potential fields algorithms to achieve navigation at moderate
walking speeds and to avoid oscillation in narrow spaces.
The experiments illustrate that passive RFID tags deployed
in the environment can act as reliable stimuli that trigger local
navigation behaviors to achieve global navigation objectives.
ShopTalk: Independent Blind Shopping Through Verbal Route Directions and Barc...Vladimir Kulyukin
Independent shopping in modern grocery stores that carry thousands of products is a great challenge for people
with visual impairments. ShopTalk is a proof-of-concept wearable system designed to assist visually impaired shoppers
with finding shelved products in grocery stores. Using synthetic verbal route directions and descriptions of the store layout,
ShopTalk leverages the everyday orientation and mobility skills of independent visually impaired travelers to direct
them to aisles with target products. Inside aisles, an off-the-shelf barcode scanner is used in conjunction with a software
data structure, called a barcode connectivity matrix, to locate target product on shelves. Two experiments were performed
at a real world supermarket. A successful earlier single-subject experiment is summarized and a new experiment involving
ten visually impaired participants is presented. In both experiments, ShopTalk was successfully used to guide visually impaired
shoppers to multiple products located in aisles on shelves. ShopTalk is a feasible system for guiding visually impaired
shoppers who are skilled, independent travelers. Its design does not require any hardware instrumentation of the
store and leads to low installation and maintenance costs.
Independent blind supermarket shopping is difficult at best. This paper presents
ShopTalk, a wearable small-scale system that enables a visually impaired shopper to
successfully retrieve specific products. ShopTalk uses exclusively commercial-off-theshelf
components and requires no instrumentation of the store. The system relies on the
navigation abilities of independent blind navigators and on the inherent supermarket
structure.
Surface-Embedded Passive RF Exteroception: Kepler, Greed, and Buffon’s NeedleVladimir Kulyukin
Surface-embedded passive radio frequency (PRF) exteroception is a
method whereby an action to be executed by a mobile unit is selected through a
signal received from a surface-embedded external passive RFID transponder. This
paper describes how Kepler’s hexagonal packing pattern is used to embed passive
RFID transponders into a carpet to create PRF surfaces. Proof-of-concepts
experiments are presented that show how such surfaces enable mobile robots to
reliably accomplish point-to-point navigation indoors and outdoors. Two greedy
algorithms are presented for automated design of PRF surfaces. A theoretical extension
of the classic Buffon’s Needle problem from computational geometry is
presented as a possible way to optimize the packing of RF transponders on a
surface.
A Software Tool for Rapid Acquisition of Streetwise Geo-Referenced MapsVladimir Kulyukin
RapGeoRef, a software tool for rapid acquistion of streetwise geo-referenced maps, is
presented. A evaluation study of RapGeoRef was performed on the USU campus with four students.
The participants were told about the purpose of the tool and shown a demo. They were
then asked to construct a geo-referenced database for an area of the USU campus. Upon
completion, they were given the NASA TLX questionnaire to assess the subjective
workload.All participants were able
to complete the task in one day. The analysis of the NASA TLX questionnaire revealed
that the temporal demand was much more prominent to the participants than either
mental or physical effort.
Ergonomics-for-One in a Robotic Shopping Cart for the BlindVladimir Kulyukin
Assessment and design frameworks for human-robot teams
attempt to maximize generality by covering a broad range of
potential applications. In this paper, we argue that, in assistive
robotics, the other side of generality is limited applicability: it is
oftentimes more feasible to custom-design and evolve an
application that alleviates a specific disability than to spend
resources on figuring out how to customize an existing generic
framework. We present a case study that shows how we used a
pure bottom-up learn-through-deployment approach inspired by
the principles of ergonomics-for-one to design, deploy and
iteratively re-design a proof-of-concept robotic shopping cart for
the blind.
