In rare cases, one-way, lecture-style delivery may be acceptable when delivering facts and you may not need the flexibility to adapt messaging to the needs of viewers. For the most part, however, even informational speeches can benefit from dynamic selection of content. Remember that audience members probably are thinking, "How does this relate to me?" Anytime those kinds of questions are possible, visual interactivity is advisable. Plus, circumstances can intervene to reduce the amount of speaking time available or otherwise necessitate a change in timing or focus. Having the ability to adjust to such circumstances can mean the difference between a marginal and a superior performance.

People like to feel a sense of connection to the speaker. They need to relate their current knowledge and perspectives with the new concepts being revealed. A speaker's willingness to answer questions and change focus on-the-fly helps them do so.
