Motivations

  • 35% of people in developed countries will be
  • ver 60 by 2050
  • Falls cause many deaths and disabilities in
  • lder adults
  • 35 to 40% of older adults over 65 fall at least
  • nce a year
  • 10% of fallers get seriously injured
  • Psychological consequences are often

neglected in care practices

Post-fall Syndrome (PFS)

  • Psychological and psychomotor consequences
  • f falls:
  • Fear of falling
  • Psychomotor disadaptation syndrome
  • PFS resembles post-traumatic stress disorder

(PTSD)

  • Virtual reality has proved useful in treating

PTSD and phobias

  • Can virtual reality help treat PFS?

Living-lab participatory design

  • Iterative design cycle
  • Basic principles:
  • Openness
  • Influence
  • Reality
  • Value creation
  • Sustainability
  • Fast prototyping

System description (1/2)

  • System features:
  • Repurposed chair with moving seat by Backwell (Israël)
  • Virtual strolling game
  • Game development in Unity using ready-for-use

graphical assets for fast iterations

Preliminary study

  • Goal: Assess feasibility and check for

safety and acceptance

  • Participants:
  • 4 males, 4 females
  • 81 < age < 94 (mean = 87.4)
  • Mean MMSE score = 25.8
  • Moderate or severe gait disorder
  • 5 with fear of falling
  • Tried moving chair and virtual reality

separately

  • Results: no pain; no nausea; positive

feedback; no obstacles to deployment

Serious game participatory design

  • Start with one environment, one avatar and one

controller

  • Participants: 8 women over 80 (1 with PFS)
  • Evolutions through testing:

2016-05-13 9

Issue Response City environment is unwelcoming Added forest and park environments Players did not identify with the avatar Added 7 extra character models Flight simulator joystick is too stiff Added support for other game controllers Older adults need time to familiarize with the controls Added tutorials explaining how to play and give players time to adapt Players keep moving their avatar when they are supposed to read instructions Freeze the avatar when instruction text is on

Game contents after iterations

  • Tutorial level explaining how to control the

avatar and the game mechanics of path following through cube collection

  • Free strolling in the forest environment
  • Cube collection task in the park environment
  • City level still available with cube collection

task

Conclusions

  • Novel method to tackle PFS through virtual

reality exposure

  • Well-tolerated and deployable in hospital

environment

  • Players enjoyed the experience
  • Virtual environments’ aesthetics are

important to older adults

  • No perfect fit for the game controller

Latest evolutions

  • Spotting other design issues:
  • Playtesting session with 9 older adults
  • Focus group with physiotherapists
  • Focus group with psychomotricians
  • Physicians’ requirements
  • Testing with 6 hospitalized older adults with cognitive

impairment and PFS

  • Changes made:
  • Added a level with single directional axis control
  • Flattened path in forest environment
  • Split tutorial in three parts (one before each level)
  • Added “easy” mode for people with cognitive impairment

Future work

  • Prototype validation study (ongoing)
  • Randomized controlled study to assess PFS

treatment efficacy and long-term benefit

  • Explore other interaction modalities
  • Enrich game mechanics with other activities,

NPCs (pedestrians) and moving objects (cars)

  • Include a virtual coach/therapist?
