Week 13: AT Flashcards
Models for AT assessment and intervention
- Human Activity Assistive Technology (HAAT)
- Student Environment Task Tool (SETT)
- Matching Person and Technology
- Child and Family-Centered Approach
HAAT
- Human Component: Cognitive, Perception, Attention, Memory, Orientation
- Activity: Activities AND participation
- AT
- Context
Student Environment Task Tool (SETT)
- Student: what do they need to do?
- Environment: physical arrangements, attitudes of others, expectations
- Task: what task will occur, what might need to be modified
- Tool: no-tech, low-tech, high-tech
Matching Person and Technology
- Milieu: characteristics of environment, psychosocial factors
- Personality: temperament (frustration tolerance), personal disposition
- Technology: functions, features
Child and Family-Centered Approach
- Culture/attitudes/values: stigma, beliefs, life roles
- Disability: social stigma, physical abilities, cognitive abilities
Role of OT in AT Evaluation and Intervention…
- Functional needs
- Environmental needs
- Task analysis
- Adapts and positions adaptive equipment
- Trains client in the use of equipment
Human-technology interfaces
- Input or control interface: The hardware used to operate or control a device
- Selection set: Items from which choices are made
- Selection methods: Direct - the individual is able to use the control interface to randomly choose any of the items in the selection set; Indirect - intermediate steps are involved in making a selection
Interfaces can be used for…
- Communication Devices: Augmentative communication, Alternative communication
- Computers
- Power Wheelchairs
- EADL (Electronic Aids for Daily Living) also know as ECU (Environmental Control Units)
Input or control interface
Alternative or Modifications to the Control Interface:
- Alternative keyboards
- Adaptations to keyboards (Key guards and shields)
- Software modifications
- Alternative mice
Direct selection method
- Fastest and preferred mode
- Physically, requires fine, controlled movement, most difficult
- Cognitively: Immediate and direct result of the selection
Indirect selection method
- Scanning and coding
- Cognitively difficult: Attention, sequencing, planning
- Requires use of switch
Use of Switches for Indirect Method:
- Activate switch?
- Wait for appropriate selection?
- Activate switch at the right time?
- Maintain switch activation (hold)?
- Release on command?
- Repeatedly carry out the steps necessary?
Adapted play
- Adapted toys
- Switches
- Simple ECU
- Positioning equipment
- Adapted light/low tech for play and leisure
Switch Interfaces: Battery interrupter/adapter
This can transform any battery operated toy or electronic device for switch activation. The copper wafer is placed against the end of the battery. A switch is connected to the jack end and operation of the switch will result in turning on the toy.
Switch Interfaces: Environmental control unit (ECU)
An interface for any electrical (plug in) appliance with an on/off switch. Any appliance needing to be tuned on or off can be controlled by a single switch.
