203：Projector controller recognizes the voice messaging, and matches phonetic order, provides specified according to special sound instruction
Project content；
204：According to volume, projector controller identification user position provides projecting direction；
205：Synchronous motor receives the projecting direction that projector controller is provided, and drives speculum and projecting apparatus synchronous axial system to arrive
To should projecting direction position；
206：Projecting apparatus receives the project content that projector controller is provided, and is projected according to project content；
207：The projected picture of projector projects is projected on the projection screen by speculum.
Next, illustrating a specific example of above-mentioned phonetic order matching by Fig. 5 and Fig. 6 is combined.It is desirable to advise
Determine the specific format of phonetic order, can just be identified.Specifically, the form of regulation phonetic order is in systems in advance
" time ", " weather ", " calendar " etc..When user provides corresponding phonetic order according to these predetermined forms, system ability
Recognize that these are instructed, and the corresponding projection display contents provided.For example, as shown in Figure 5, when user sends phonetic order
When " Time ", the induction module being arranged on projection screen gathers the voice messaging, and the voice messaging is sent into projection control
Device.The latter is analyzed the instruction, and it is the phonetic order with time correlation to find it, then correspondingly provides the current time
Information (i.e. projection display contents).Meanwhile, according to the phonetic order (being specifically its volume), projector controller can also be sentenced
Break and sound source position (i.e. user position), the sound source position based on the judgement determines corresponding projecting direction, and controls same
Projecting apparatus and speculum are turned to position corresponding with the projecting direction of the determination by step motor.Finally, such as institute in Fig. 5 and Fig. 6
Show, this follows the project content that projection arrangement is provided according to projector controller, projected in the projection screen region in face of user aobvious
Show current temporal information " 23 days 17 May in 2017:54 points ".
