• An Exploratory research project• IPO Model Input: user characteristics, message/task

characteristics… Process ： two interacting use subprocesses of

exploration and experimentation, assessment Output ： outcome of the use process, the

actual adoption decision/behaviors

Inputs: Factors influencing use

• Individual Characteristics -Age -Technology self-efficacy -Cultural origin

• Technology Characteristics -Interface -network capabilities

• Communication/Task Characteristics -Number of interacting participants -Immediacy of response desired -Volume of response desired -communication objectives

• Modalities of Mobility -Traveling, wandering, and visiting

Inputs: Factors influencing use

• Context -Economics factors and technological infrastructure -Social factors -Critical mass

Inputs: Factors influencing use

The Use Process

First Step– Choice of appropriate medium of communication

and the level of synchronicity– Choice of extent mode, and exclusiveness of use– Adjustment of cognitive frame regarding

technology

The Use Process

Second step– Functional Impact on functional effectiveness and efficiency

and on interpersonal relationships– Psychosocial

Psychosocial outcomes– Relational Changing relationships among individuals

Output—adoption outcome

• continuity of use over time • resource commitment

A positive experience with the use process, reflected in favorable assessment in terms of functional, psychosocial, and relational, outcomes, influenced adoption decisions and behavior.

Conclusion

The areas of m-communication and m-commerce are promising, yet confusion is abundant. While we do not claim the findings presented here are exhaustive, we are hopeful the holistic framework presented will be valuable in advancing knowledge in the emerging area of m-communication and m-commerce.

• 感知的有用性 (perceived usefulness) 反映一个人认为使用一个具体的系统对他工作业绩提

高的程度• 感知的易用性 (perceived ease of use)

反映一个人认为容易使用一个具体的系统的程度

• 外部变量包括系统设计特征、用户特征 ( 包括感知形式和其他个性特征 ) 、任务特征、开发或执行过程的本质、政策影响、组织结构等等

Task-Technology Fit

任务－技术适配

技术特性 应用

影响绩效任务特性

• 没有满足组织任务的需求会减低组织对该服务的有用性认知，同样会降低该服务的易用性认知

• 只有当信息技术的功能很好的支持组织的任务需求时，技术才会被采纳

• 考虑到技术特点如何影响技术的使用
