D2.1 Requirements and Specification - CORBYS

Recommendations

Info

D2.1 Requirements and Specification deliverable will have to formally set out all the relevant epistemology (the structure of knowledge) and teleology (the theories of sense-ful action and purpose) essentially at two levels of abstraction: i) Generic CORBYS Framework Architecture Requirements, ii) Domain-Specific Requirements for each Proof-of- Concept Demonstrator Domain; i.e. for the Gait Therapist Assistant, and, the Hazardous Area Examining Assistant applications. Thus the aim of this deliverable is to focus on a formal explication of the knowledge needed to help specify the requirements to be fulfilled by the CORBYS Architecture during the various modes of its operational life i.e. during: i. configuration ii. usage iii. goals (re)setting iv. maintenance, v. validation and vi. refinement Phases of the CORBYS system operation It is also important to clarify that we recognise at least two CORBYS user groups: i) the CORBYS Professional User or CORBYS Expert User who would prescribe the manner in which the CORBYS system should be (re)configured, and have its goals (re)set so as to provide a sense-ful and useful service with maximum benefit to the end-user, and, ii) the CORBYS End-User who would be the human engaged in some activity that is intended to be directly supported through timely and gracefully cooperative initiatives taken by the CORBYS system to help the human in achieving his goals. Thus the CORBYS Consortium Partners should make contributions for this deliverable, each according to their expertise-related responsibilities and the level of planned effort; to respond to the questions re: What the design, development and validation of a CORBYS system needs to know about: process-flows, states, spaces, observability, controllability, degrees of freedom, resources constraints, optimal timing, interfaces etc relevant to the intervention steps by a cognitive system architecture to support man-machine interactive-cooperativity for the integrated man-machine system as a whole to achieve a given target state (goal state) as may be set by the domain experts e.g. i) by a gait therapist, or, ii) by a hazardous area examination officer – who are the typical practitioner users in the two CORBYS Project Demonstrator domains. Accordingly the design of the CORBYS framework architecture has to be informed by the epistemology i.e. the structure of knowledge relevant to both the general principles of man-machine mixed initiative-taking system design, and, the ontology of the two application arenas chosen as the Demonstrator proving grounds. Such application domain ontology includes the semantic parametrics of the entities, states and processes, goals as well as the spatio-temporal and resource constraints appertaining to each of the two demonstrator domains From the above observations follows our action plan which is to formalise the relevant knowledge structured within 9 facets of the domain with a focus of our analysis base as outlined in the indicative contents to be agreed under each of the relevant 10 sections set out below. For each of the facets, by reference to a uniform 4
D2.1 Requirements and Specification analysis set (of entities, states, processes, constraints and requirements) we seek to examine and identify all the requirements relevant to the design and validation of CORBYS as a framework Cognitive Systems architecture and for its demonstrator domains. The 9 facets of our requirements analysis and elicitation are as follows: i) The Human System ii) The CORBYS Mechatronic System iii) The CORBYS Cognitive System iv) The CORBYS Learning (on/offline) Component v) The CORBYS Testability, Validation and Usability Evaluation Framework vi) The Operational Environment Parametrics vii) The Demonstrator Application I: Robot-assisted Gait Rehabilitation viii) The Demonstrator Application II: Robotic examination of hazardous/contaminated areas ix) Socio-technically acceptable CORBYS Solution System and its Business Model Sustainability 4 Requirements Engineering Analysis Base 4.1 Knowledge elicitation from clinical experts for Demonstrator I This section sets out the requirements of the first CORBYS demonstrator resulting from discussions among relevant partners of the Consortium including NRZ, IRSZR, OB, OBMS, VUB, UB, and UR. 4.1.1 EndUser Demographics End-users of the CORBYS demonstrator I, gait rehabilitation system, are patients, who could have the following diseases and handicaps: � Lesions or diseases of the central nervous system such as traumatic brain injury (incidence of severe TBI in Germany 30.000), stroke (of 250.000 patients suffering from stroke yearly in Germany approx. 30.000 could benefit from a walking aid system), encephalitis, hypoxic brain injury before or during birth Preterm birth (= infantile cerebral palsy, incidence in Germany 3000), or during later life (= due to cardiac disease or suffocation), degenerative brain diseases such as Parkinson´s disease (36.000), inflammatory brain diseases such as multiple sclerosis (56.000), or brain tumors. Lesions of the central nervous system lead to spastic paresis (=increased muscle tone) and the need for re-modelling by exerting repeated exercises and active-corrective. � Diseases and trauma of the spinal cord (5000). Lesions of the spinal cord also lead to a spastic paresis, but there is little chance for re-modelling � Diseases of the peripheral nervous system such as Guillain Barré syndrome, polyneuropathies, or neuromuscular diseases (disabling approx. 10.000). Lesions of the peripheral nervous system lead to a flaccid paresis (= reduced muscle tone) and the need for support and gaining strength � Orthopedic problems such as endoprothesis of knee (in Germany 160.000) or hip (in Germany 210.000). Patients would benefit from a gait training system during the first 1-2 weeks after operation Depending on the site and size of the lesion, patients suffer from pareses of one to four limbs: hemi- (arm and leg of one side), para- (both legs), tetra- (all four limbs) or monoparesis (one limb). Additionally, other movement disorders can occur alone or in combination with paresis: ataxia (uncoordinated movements) or 5
