Joshua Brown

Haptics Research Associate | Imperial College London

joshua.jpg

Chelsea and Westminster Hospital

369 Fulham Road,

London, United Kingdom

I’m a Research Associate (postdoc) at Imperial College London where I work at the intersection of robotics, human-computer interaction and surgery. I am based in the Simulation and Modelling in Medicine and Surgery (SiMMS) group in the Department of Surgery and Cancer. My primary research interest is in haptics though my past research has covered topics including digital manufacturing, personalised medical devices, robotics for muscular rehabilitation and information visualisation. I am currently working on haptic simulations of physical medical examinations which will be deployed to support Imperial’s MBBS in Medicine curriculum.

I first joined Imperial as an undergraduate student in the Department of Electrical and Electronic Engineering in 2014, before returning as a researcher in Bioengineering in 2020. I am currently with the Department of Surgery and Cancer as part of the Centre for Engagement and Simulation Science and SiMMS research group. I completed my PhD in Haptics at Queen Mary University of London and have been a visiting researcher at York University in Canada and Seoul National University in South Korea. I am also a co-founder of Human Robotix Ltd.

AI Coffee Machine

One interesting HMI project I was able to take part in during my undergraduate degree was the creation of an internet connected, mechatronic exoskeleton for an office coffee machine. The project was set and sponsored by IBM, who at the time were interested in ways of retrofitting smart functionality to traditional household applicances.

Project Aims

  • To better understand the visual impact of two strong visual perspective cues: magnification and environmental artefacs.

  • To investigate (in a specific and limited way) the hypothesis that humans have an evolutionary preference for 3D environments.

  • To investigate the possibility of a previously unidentified visual cue, rotation, via the Deep-Flat optical illusion.

Non-Invasive Modification

The obvious approach to adding smart functionality to ‘dumb’ appliances is to add a small microcontroller to simulate the inputs from the various manually operated switches and knobs. One of the aims of this project, however, was to create a system that could be fitted by an end user, meaning that it became necessary to develop mechanical solutions to the problems of how to press a button or how to turn a dial. Reading status outputs externally was also a challenge, as bi-colour and flashing LEDs all report vital information which needed to be transmitted to the smart system. The resulting product was therefore effectively an exoskeleton around the machine, which used voice commands, a GUI and web interface for user input.

COVID-PPE

Community engagement and impact

In March 2020, at the start of the global COVID-19 pandemic, the UK’s supply chain for medical grade PPE collapsed under unprecedented demand and a workforce that could be sent into quarantine at a moment’s notice. As a result frontline clinical staff in some of the UK’s busiest hospitals were left to care for patients without adequate protective equipment. To respond to this, a coalition of experts in medicine and surgery, medical devices, product design and digital manufacturing was formed between Queen Mary University of London and the Royal London Dental Hospital to design safe, effective and reusable PPE (Personal Protective Equipment) that could be manufactured quickly to meet the urgent demands of London’s hospitals and medical and dental surgeries.

You can also have artistically styled 2/3 + 1/3 images, like these.

Outcomes

This project resulted in the manufacture of over 3,000 3D printed face visors, and a further 20,000 injection moulded visors which were distributed to hospitals, schools and community medical practices within days of the nationwide PPE shortage. These were also the second 3D printed face visors to gain regulatory apporoval (CE mark) in the UK, and the first to be specifically designed for high-risk aerosol generating dental procedures. The accompanying paper, “Innovation in the time of SARS-CoV-2: A collaborative journey between NHS clinicians, engineers, academics and industry” was published in the Journal of the Royal College of Surgeons of Edinburgh and goes into more detail about the manufacturing and logistical steps required to design and distribute a product, from scratch, within a matter of days.

To respond to this, a coalition of experts in medicine and surgery, medical devices, product design and digital manufacturing was formed between Queen Mary University of London and the Royal London Dental Hospital to design safe, effective and reusable PPE (Personal Protective Equipment) that could be manufactured quickly to meet the urgent demands of London’s hospitals and medical and dental surgeries.

Outcomes

This project resulted in the manufacture of over 3,000 3D printed face visors, and a further 20,000 injection moulded visors which were distributed to hospitals, schools and community medical practices within days of the nationwide PPE shortage. These were also the second 3D printed face visors to gain regulatory apporoval (CE mark) in the UK, and the first to be specifically designed for high-risk aerosol generating dental procedures. The accompanying paper, “Innovation in the time of SARS-CoV-2: A collaborative journey between NHS clinicians, engineers, academics and industry” was published in the Journal of the Royal College of Surgeons of Edinburgh and goes into more detail about the manufacturing and logistical steps required to design and distribute a product, from scratch, within a matter of days.

Surgical Stents

Creating clinical impact through design and manufacturing engineering

Odontogenic cysts are fluid-filled voids in the jaw that can cause severe and painful swelling of the face. Treatment often involves drainage and promoting new bone growth in the empty space. Traditionally, surgeons might utilize an open surgical approach to drain the cyst and pack the cavity with bone graft material from the arm or leg. As well as being a long and expensive procedure, this can leave a significant opening in the jaw requiring facial stitches and a long recovery. An alternative, minimally invasive approach drains the cyst through the mouth and, rather than performing a bone graft, allows the bone is allowed to regrow naturally. To allow the cyst to be kept clean whilst healing, a nasopharyngeal tube is inserted down into the cyst via the gingiva. While preferable, this method can be uncomfortable for patients due to the tube’s irritating presence in the mouth, and there is an ongoing risk of food or other foreign bodies entering the cyst. This project investigtaed soft mateiral 3D printing as a way of producing personalised stents [1].

Research Aims

  • Investigate whether 3D printing is a viable method of producing personalised surgical implants

  • Identify safe, soft 3D printable materials to use for manufacturing decompression stents

Stent design

The stents are customised for each patient, but feature: a semi closed end with a one-way valve to exclude food debris from the cyst and several slots to aid in suturing to the gingiva; a bell shaped end to aid in the positioning of the stent inside the gingiva and opening into the cyst; an optional angled profile to allow the stent to be more easily located around the patient’s remaining teeth. The dimensions of the stent are determined for each patient and usually based on a 3D printed model of the patient’s skull, reconstructed from CT scans performed whilst investigating and diagonsing the cyst.

Material selection

The stents are manufactured from silicone on a Formlabs 3D printer. Silicone is non-irritating and has low water absoption which is essential inside the mouth - generally considered a hostile environment for many materials. Additionally, silicone is soft, making the stent more comfortable for the patient to accommodate in the mouth for an extended period of time (generally 6 months or longer).

Clinical impact and use

The stents are now being used with patients in several London hospitals. Odontogenic cysts are uncommon in the UK, however are extremely common in South Asia and Africa, where the project team also has strong clinical links. Early patients have been monitored and show good bone regrowth after around 6 months.

Wrist Manipulation Robot

Startup Company

In 2011, the Human Robotics Group at Imperial College London designed and built Hi5 - a high performance torque feedback interface for the wrist which has been used in studies ranging from human motor control to haptic sensations and even physical treatments for neurodegenerative disorders like Parkinson’s disease. In 2020, I returned to Imperial College tasked with taking the full sized robot and producing a portable, commercialisable version.

The HRX-1 wrist manipulation robot.

The result - the HRX-1 - is a fully portable reimagining of the original robot. At less than 10KG fully packaged, it can be easily transported between research labs, clinics and researchers’ or patients’ homes. It’s 600W brushless DC motor can generate up to 4Nm of torque and the handle can measure up to 11Nm of input torque. Software is provided for control and data logging through MATLAB, which also offers integration with a variety of other devices, sensors and software packages.

The robot is now being sold through a start-up - Human Robotix Ltd. Based out of my garage in South-East London, each robot is proudly built in Britain. The robots are already being used in universities in Europe and North America with hopefully more to come.

Robo-Chick

Investigating haptics in Animal-Robot Interaction

I spent 2019 working with a team of animal psychologists to study the effects of multi-modal stimulation on infant chicks (0-5 days old). This has involved designing and building relatively compact robots to vibrate and play sounds when pecked by a chick. It is hoped that the results from this study will inform ongoing effors to automate chicken farming using robotic and electronic devices, as well as ever fascinating strides toward creating realistic, helpful, robotic pets.

Research Aims

  • To investigate the effect of physical (vibrotactile) stimulation on infant chicks.
  • To propose a machine learning approach to classifying chick calls.
  • To inform future developments in the field of agri-robotics with ah emphasis on improving animal welfare.

Social Robots

Social robots are robots whose key purpose is to elicit some form of attachment in another agent, rather tham providing a more conventional service. Unlike many conventional social robotics projects, this exercise aims to develop social robots for animals. To this end, we take a multimodal approach to interaction design, with experiments ongoing to study the use of visual, auditory and tactile stimuli, as well as the automated classification and understanding of auditory calls from infant chicks.

3D Printed Surgical Models

Real-feel surgical simulators

Complex surgical procedures are difficult to train with computer generated simulations due to the dexterity required by surgeons. In some cases, physical models cannot be matched, however commercially avaialble models are expensive and often oversimplified to be easily mass producable. This project investigates 3D printing and silicone casting as a means of producing highly accurate surgical models with realistic anatomy and tactile feel.

Research Aims

  • To investigate ways of using 3D printing to produce highly realistic surgical models
  • To assess which surgical specialisms can benefit from physical anatomical models for simulation training
  • To evaluate the benefit of physical models for training surgeons in complex procedures
  • To identify affordable and easily workable materials that can realistically simulate the properties of soft tissues

Orthopaedic Hand Surgery

The first model I was involed in creating was a simulation of a carpal tunnel patient. In carpal tunnel syndrome, the transverse carpal ligament traps and exerts pressure on the median nerve, so it must be cut open to release pressure on the nerve. To do this, an incision is made in the palm of the hand and the ligament cut from below. A CT scan of a real hand was used to create a skeleton and skin model, which were composited together to make a mould that could accommodate 3D printed plastic bones. A section of the palm of the hand was then cut away and redesigned to feature the major tissue layers that a surgeon would expect to encounter whilst making their incision: skin; superficial fat; fascia; deep fat; ligament; and muscle. A nerve was pre-cast and inserted under the ligament before casting. The model is currently undergoing being validated with hand surgeons at several London hospitals.

Underwater Robot Teleoperation

Applied haptics

Towards the end of my PhD, I was able to visit York University in Canada to conduct a study investigating the usefulness of haptic feedback when presenting environmental information from a teleoperated underwater robot. This consisted of an experiment in which my interactive soft haptic touchpad was connected to a Blue Robotics BlueROV2. The touchpad was used to control speed and direction whilst the robot passed through a cross-current to reach and inspect a floating target.

Research Aims

  • To understand the usefulness of multimodal haptic feedback in interpreting the movements of a remote robot.

  • To understand how different aspects of the robot’s motion and environment can be represented by different haptic effects.

  • To assess the benefit of haptic feedback in a difficult real world task.

Particle Jamming

Particle jamming refers to an active area of research in condensed matter physics. The jamming of particles in a fluid has been proposed as a physical phase transition and refers to a state where the particles that make up that fluid are packed in such a way that they are physically connected to any adjacent particles. Jammed fluids are, by definition, denser than the same material in an unjammed state, and this leads to many changes in their properties, such as increased viscosity and stiffness.

Prorotype Haptic Device

A prototype for a novel haptic device based on the particle jamming effect described above was completed in early 2019 (photo at the top of the page) and very kindly funded by the IEEE Technical Committee on Haptics. The initial prototype consists of a rigid case filled with small particles, covered by a silicone touch pad. This mechanical device can be connected to an electronic vacuum regulator to control the strength of the jamming effect. This device uses a simple vacuum pump to generate an area of low pressure inside the case, forcing the soft cover into the device and causing the particles to jam. An ERM type vibrating motor is loosly suspended in the fluid to provide vibrations which are then restricted by the jamming of the particles.

User Studies

Once the phsyical characterization of this device is completed, I plan to undertake some simple user studies to determine the psychophysical effect of using particle jamming to control the ‘intensity’ of the vibrations. I will then use the device, either on its own or integrated into a joystick or other computer input device, to perform a number of application based experiments such as material identification from a recorded vibrotactile texture and telerobot control in difficult environments, for example underwater in the presence of a strong cross-current.

Walking Aid - Limitless Living for the Elderly

During the final year of my degree, I was part of a team of students working on a robotic walking aid to improve mobility and activity levels among the elderly and disabled. This consisted of a number of ‘passive’ features to make moving around without a wheelchair easier. Unfortunately, course constraints prevented us from undertaking any extended user studies with our system, but the project was still a fun and interesting effort to produce a robot for a demographic that can sometimes have a fraught relationship with technology.

Research Aims

  • To improve activity levels among elderly and disabled people.
  • To investigate technological approaches to early diagnosis of lower-limb affecting skeletal and neurological disorders.

Obstacle Avoidance and Differential Braking

One of the key aims of the project was to improve activity among elderly people through the use of technology. One factor we identified as an inhibitor to activity is lack of confidence in being able to navigate what can be quite busy, constrained indoor environments. The smart walking aid attempts to combat this with an array of distance sensors to detect static obstacles and steer the user away from them. For safety reasons, and so as not to remove the user’s sense of autonomy, we decided not to outfit the walking aid with a powered propulsion system, so I devised a system of differential braking that would steer the user away from objects in their path without actually powering the walking aid’s wheels.

Fall Detection

An important aspect of activity and wellbeing for elderly and disabled people is independence. We therefore wanted to develop systems that would make it easier for users to walk in the walking aid without needing carers to escort them. A solution to one part of this problem was the development of a fall detection system that would register if the user had fallen over and alert emergency services and/or relatives to the user’s situation and location. This was done using a combination of an IMU fitted to the user’s belt and a body tracking camera.

Gait analysis

As an extension of the initial project, aimed at mobile healthcare technologies, we were challenged to develop a system that could use machine learning to warn of possible abnormalities in the user’s gait that might indicate a sleletal or neurological disorder. A more advanced visual lower limb tracking system was developed for this, as well as grip force sensors in the walking aid’s handles. This was used to record medical students mimicing several recognised abnormal gaits, with machine learning software then matching the symmetry and step periodicity against the user’s gait. Recordings of abnormal gaits are then saved on a smartphone app for review by medical professinals, who can make a proper assessment and give an offical diagnosis if they deem it necessary.

A solution to one part of this problem was the development of a fall detection system that would register if the user had fallen over and alert emergency services and/or relatives to the user’s situation and location. This was done using a combination of an IMU fitted to the user’s belt and a body tracking camera.

Gait analysis

As an extension of the initial project, aimed at mobile healthcare technologies, we were challenged to develop a system that could use machine learning to warn of possible abnormalities in the user’s gait that might indicate a sleletal or neurological disorder. A more advanced visual lower limb tracking system was developed for this, as well as grip force sensors in the walking aid’s handles. This was used to record medical students mimicing several recognised abnormal gaits, with machine learning software then matching the symmetry and step periodicity against the user’s gait. Recordings of abnormal gaits are then saved on a smartphone app for review by medical professinals, who can make a proper assessment and give an offical diagnosis if they deem it necessary.

Haptics in Medical Training

Haptics and XR for Medical Education

Medicine is an inherently hands-on field of study, with students needing to learn important dexterous clinical skills used in physical examination and surgery. Whilst students are often given opportunities to practice these during placements and residencies, these opportunities are inherently ad-hoc and there is never any guarantee that a medical student will encounter a full range of examinations and conditions during their time in hospital. Student experience in some supernumary specialisms such as dermatology is particularly inconsistent. This project aims to combine haptics and extended reality to create realistic, instructive simulations of the physical examinations taught in the undergraduate medical curriculum to allow students to learn and practice these skills in a consistent and low-risk environment before being asked to perform them on a patient.

Research Aims

  • Investigate the challenges in teaching manual skills to medical students
  • Investigate approaches to simulating soft tissues using haptic devices
  • Explore the benefits of haptic extended reality simulations on student engagement, information retention and confindence

Physical Exmaination

Undergraduate medical students need to learn a wide range of physical examinations, from intimate examinations of the rectum and breast to complex and highly procedural examinations of the neurological end vascular systems. These are examined during medical school throigh practical examinations known as OSCEs which students must pass to continue their studies. Whilst some of these examinations are taught using benchtop models, students usually practice examinations on healthy peers or simulated patients, recieving limited feedback and no exposure to pathology. This project focusses on four physical exmainations for which there is not currently any educational simulation: dermatology, lumps, vascular, and the peripheral neurological examination.

Virtual reality simulations of an abdominal exmaination (L) and neurological examination (R)

The Role of Haptics

The advantages of including haptic feedback in simulations of physical exmainations is obvious. When examining a lump, a doctor must take note if it’s hardness, texture, mobility, any indications of fluid build up or plusation. Similarly, an examination of the vascular system may reveal high or low skin temperature (indicaitng abnormal blood flow) and a variety of pulse characters. Using haptics to simulate these physical symptoms teaches students to recognise potentially subtle or unintuitive indications, and has the potential to coach dexterous skills that are often missed in conventional teaching.

Deployment and Impact

The project is a collaboration with the Imprial College School of Medicine. Medical students will participant in pilots of the simulations during their clinical skills and methods classes, and work is underway to organize the long-term inclusion of these simulations in the undergraduate medical curriculum.
