This paper describes the methodology and procedure of usability trials undertaken as part of the ACTS Teleshoppe project; it also details and analyses the results of the trials. The aim of the trials was to assess user attitudes to a collaborative shared-space shopping service. Usability data were obtained using a series of Likert-style questionnaires and through a `focus group' discussion performed with a representative subset of the trial participants. The paper presents this data and draws conclusions relevant to the future direction of research and implementation for such shopping services. In particular, the results of the trials indicate a generally positive attitude towards the collaborative shopping service used. Furthermore, those aspects of the service viewed negatively by the users are for the most part aspects which can be easily rectified and not due to technological limitations.
