A lectern is an essential piece of equipment for almost all speeches and presentations. They come in many forms and range in degree of professionalism depending on the occasion. Lecterns not only hold a presenter’s notes, a microphone, or other presentation aids, they provide a structure for a presenter that can bolster their confidence during a presentation. As such, it is important that all presenters have a lectern available to them. Unfortunately this is not always the case due to lectern accessibility limitations. This problem inspired the Cal Poly Disability Resource Center to request a lectern that satisfies the Least Restrictive Environment criterion by creating a system that can accommodate the needs of all people, with and without disabilities. It should make the individual as independent as possible with as few adaptations possible, while maintaining a high level of functionality and grandeur. The purpose of this project is to design, build, and test a lectern that can be used at Cal Poly San Luis Obispo for presentation at various location around campus. This report details the entire design process that was used to develop the final concept: design, build, and test. The main function of the final lectern design that allows it to accommodate the widest range of users is its height adjustability. It can adjust to heights ranging from approximately 26 to 52 in. Additional features designed to accommodate the needs of the user include an adjustable worksurface and a roll-on pressure pad actuation system.
