Introduction

Problem Statement

We live in an ageing society, the number of elderly people is ever increasing (OECD, 2007) [1]. As a consequence, pressure on caregivers is also rising. Researching possibilities to alleviate this pressure by means of a robotic platform is what we are going to do in the following eight weeks. However this platform cannot be any platform since the emotional comfort is vital in medical environments (ANR, 2005) [2]. As a result our research will have as main focus the emotional response of elderly people in the presence of such a robotic agent. Except for the emotional response the dignity of this robotic platform will be assessed as well. Since our group is a multidisciplinary team this problem will be approached from both a technical perspective and a user centered perspective.

Initial ideas

Objectives

To get a better overview of what needs to be done to complete the project, we set ourselves a couple objectives:

System objectives:

  • The system should be able to express emotions in a manner that is natural, non-ambiguous and clear.
  • The system should behave like a human, without entering the uncanny valley.


Research objectives:

  • We want to understand how elderly react to different facial emotions/designs expressed by a robot.
  • We want to optimize the way that robots show emotions to elderly-users.

State of the Art

Different themes related to our project can be identified. They are listed here, together with the relevant papers that provide the stated information.

Robot emotion expression

Different papers provide an insight into the existing technology in the field of recognizing human emotion in HCI research.[3] Article 1 provides a discussion of existing literature on social robots paired with care for elderly suffering from dementia. It also discusses what contributions and cautions are bound to the use of these assistive robotic agents, and provied literature related to care of elderly with dementia.[4] Article 2 places its focus on the more general user, and contains a study about the effect of a robot's expressions and physical appearance on the perception of said robot, by the user.[5] Article 3 and Article 4 present a description of the development, testing and evaluation of a robotic system, and a framework for emotion interaction for service robots, respectively. Article 3 focuses on the development of EDDIE, a flexible low-cost emotion-display with 23 degrees of freedom for expressing realistic emotions through a humanoid face, while Article 4 presents a framework for recoginition, analysing and generation of emotion based on touch, voice and dialogue.[6][7] The results of a different project, KOBIAN, are described in Article 5. Here, different ways of expressing emotions through the entire body of the robot are tested and evaluated.[8]


Emotion recognition

In Article 6, titled "Affective computing for HCI", multiple broad areas related to HCI are adressed, discussing recent and ongoing work at the MIT Media Lab. Affective computing aims to reduce user frustration during interaction. It enables machines to recognize meaningful patterns of such expression, and explains different types of communication (parallel vs. non-parallel).[9] Article 7 consists of a large elaboration on emotion, mood, effects of affect which yields performance and memory, along with its causes and measurements. There is an interaction of affective design and HCI.[10] A study on emotion-specific autonomic nervous system activity in elderly people was done in Article 8. The elderly taking part followed muscle-by-muscle instructions for constructing facial proto-types of emotional expressions and re-lived past emotional experiences.[11] Reporting on two studies, Article 9 shows how elderly have difficulty differentiating anger and sadness, when shown faces. The two studies provide methods for measuring the ability of emotion recognition in humans.[12] Lastly, a definition of several emotions and their relation to physical responses is needed (breathing, facial expressions, body language, etc.). Article 10 describes how a computer can track and analyse a face to compute the emotion the subject is showing. Useful as an insight in how input data can be gathered, analysed and used for the purpose of mimicking or mirroring by a robot.[13]


Assistive technology for elderly

This category focusses mostly on robotic care for elderly living at home. Articles such as article 15 [14] and article 11 [15] explore the effect of robots to the social, psychological and physiological levels, providing a base for knowing what types of results certain actions yield. Article 14 [16] explores six ethical issues related to deploying robots for elderly care, article 13 [17] provides more knowledge when it compares children, elderly and robots and their roles in relationships with humans. Article 12 [18] looks at the available technologies for tracking elderly at home, keeping them safe and alerting others when needed.


Dementia and Alzheimer's

Closely related to elderly are the diseases Dementia and Alzheimer’s. These diseases affect the brain of a patient, making them forgetful or unable to complete tasks in their day-to-day life without help. Article 16 [19] elaborates on this and explains the impacts and a possible framework to counter these diseases is proposed. Article 17 [20] discusses whether an entertainment robot is useful to be deployed in care for elderly with dementia.


Measuring tools

Here, papers are collected that provide aid for designing a robotic system, article 18 [21] discusses some of the difficulties in measuring affection in Human Computer Interaction (HCI). For designing a system that is capable of expressing emotion, article 19[22] and article 20 [23] show recent developments when designing a ‘face’ or whole body to express emotion to a user.


Miscellaneous

In the study of emotions, models are often useful. Article 21 elaborates on social aspects of emotions, together with the implementation in human-computer interaction. A model is tested and accordingly a system is designed with the goal of providing a means of affective input (for example: emoticons). [24]

Article 22 describes emotional comfort was researched in patients that found themselves in a therapeutic state. It provides an understanding of the role of personal control in recovery and aspects of the hospital environment that impact hospitalized patients’ feelings of personal control.[25]

A more medical approach is taken in Article 23: evidence is provided for altered functional responses in brain regions subserving emotional behaviour in elderly subjects, during the perceptual processing of angry and fearful facial expressions, compared to youngsters.[26]

Statistics about the greying of global population provide insight in challenges paired with this greying. Article 24 is a collection of evidence for the greying of the wordl's population, with causes and consequences. It states three challenges.[27] Article 25 indicates the importance of a healthy community to the efficiency and economic growth of said community. It points out the goals of improving the healthcare system and how these improvements can be made.[28]

Interview Guide

INLEIDING - vragen bedoeld om de mensen vast in het thema te laten denken.

  • Zou u een robot kunnen vertrouwen? Wat heeft u nodig om een robot te kunnen vertrouwen?
  • Wat verwacht u van een robot?
  • Welke positieve/ negatieve ervaringen heeft u al met robots? Wat zou u graag anders zien aan robots?
  • Zou u gebruik willen maken van een robot? Waarom wel/niet?
  • Hoe zou je willen dat het gezicht van een robot eruit ziet?
  • Wat voor materiaal zou je willen hebben bij een robot?

ROBOT IN DE ZORG- VRAGEN

  • Wat is, voor u, het belangrijkste aan het ontvangen van zorg?
  • Wat zou u er van vinden, deze zorg van robots te ontvangen?
  • Welke taken denkt u dat een robot kan uitvoeren in de context van (thuis)zorg?
  • Hoe belangrijk vindt u het, dat contact met uw verzorger emotioneel is?
  • Welke eigenschappen moet een robot hebben om betrouwbaar te zijn/over te komen?* Wil je liever dat een robot zijn emotie prettig/comfortabel of duidelijk is?

TESTPLAN

Test 1

  • Select various shapes (squares, triangles, circles), and variations of these shapes (tall, broad, small, large, etc.)
  • Show these to people and ask them to rate them on likert scale of emotions
  • Use 6 basic emotions: happiness, anger, sadness, surprise, disgust, fear
  • Sidenote: movement/dynamic shapes not included in this test, while the transitions between shapes may affect the implied emotion.
  • Sidenote: no knowledge is gained about the expected, context-dependent reaction of an emotional interface (i.e. nuance in mirroring emotion; laughing when expected to be angry; etc.)
  • Alle vragen doornemen met de ouderen, aan het einde van de vragenlijst, de vragen doornemen om meer inzichten te kunnen krijgen.
     * Welke van de vormen zou u het liefst in een gezicht zien?
     * Welke van de vormen zou u het liefst zien als ogen voor een robot?
     * Welke van de vormen zou u het liefst zien als neus voor een robot?
     * Welke van de vormen zou u het liefst zien als mond voor een robot?

Doel van deze test is erachter komen welke vormen het meest toepasselijk zijn voor het gebruiken als communicatiemiddel voor emoties.

Test 2

  • Select various robots displaying emotions from visual media.
  • Rank robots on the amount of humanity displayed
  • Ask questions about the various pictures:
  • Which is preferred for tasks inside their personal space?
  • What emotion expresses the emotion angry/happy/etc. the best/the most clear?
  • Welke robot vond u het vrolijkste (met alle emoties)?
  • For various tasks, which robot would you pick to do this task?
    - Stofzuigen
    - Koffie zetten
    - Medicijnen geven  
    - Eten geven/koken 
    - Hulp met douchen
    - Activiteiten: schilderen, etc.

Side note: we are aware of the fact that there may be some bias met de characters van de robots.

Doel van deze test is een richtlijn vinden om te zien welke trekken van een robot, daarbij ook welke mate van menselijkheid gewenst is voor een robot die ouderen zouden gebruiken in hun eigen omgeving.
