Figure Lengend Snippet: (a) Diagram of the entire system showing the prosthetic eye (A), the servo-motor (F) and associated micro-controller (E) to control the direction of the eye, the eyewear (D) that contains the main antenna, the beam splitter (B) that channels the VCSEL beam (represented as a red solid line) towards the IR camera (C) (located above the eyewear). (b) A prototype image. (c) Eye tracking lens electronic circuit and componentry, (d) the vertical cavity surface emitting laser spot captured by the IR camera at five different orientations: −20°, −10°, 0°, 10°, and 20°, and (e) the graph depicts the coordinates of the vertical cavity surface emitting laser spot corresponding to these five orientations (Reproduced by permission of ref .).

Article Snippet: Khaldi et al. developed a prototype eye-tracking lens, which involved encapsulating the integrated electronics and components, such as the primary and secondary antenna and optoelectronic circuitry, within the CL using Loctite glue ( and ).
