在用户在三个不同级别参与工作的过程中，将调查有特殊需求的人对钥匙尺寸和钥匙间距的要求。PT16V的报告将这些项目作为标准化问题优先考虑。丹麦技术援助中心在评估有特殊需要的人的电话时也认识到了这一需要。该工作项将作为心脏项目a线工作包a.3用户参与标准化和测试要求案例研究的一部分进行。

In a process where users participate in the work on three different levels the requirements for key size and key spacing for people with special needs will be investigated. These items are prioritised as standardisation issues in the report from PT16V. Also the need has been recognised by the Danish Centre for Technical aids when assessing telephones in respect to people with special needs. The work item will be carried out as a part of the Heart project, line A, workpackage A.3 Case study in user participation on standardisation & testing requirements.
