- 2. What is a Smart Projector? • A Smart projector is a small hardware device designed to project content from a smartphone, camera, tablet, notebook or memory device onto a wall or other flat surface. • Smart projectors use either an LED or laser light source which effectively eliminates the need for lamp replacement over the useful life of a projector. • Smart projectors are tiny battery powered projectors-as small as a mobile phone-or even smaller : these projectors can even embed inside phones or digital cameras.

- 4. Tech. Classification into 4 Buckets Emerging Technology Virtual Reality in a projector- enables setup; a French start-up Catopsys are doing R&D to provide a panoramic, virtual reality image throughout a room for gaming. Key Technology Voice-assistance command (Alexa), App-Based controlling systems are providing a competitive-edge over traditional projectors with only base technology. Base Technology Liquid Crystal Display, controls how much light each pixel gets and forms the base technology of projectors. Pacing Technology There has been discussions on applying Raspberry Pi (IoT) – Single computer board, as 98% of phones are driven through this tech. Would help in ease of sending files directly to the projector.
- 5. It is a technology that basically involves using tiny mirrors on a chip that directs light from a white light source. Each tiny mirror controls a pixel on the target picture, and depending on how long it’s on, the target pixel gets brighter or dimmer, since it has only on and off states. Between the light source and the mirrors, is a color wheel that splits light into the three primary colors(red, green & blue) & each mirror controls all three light beams for its designated pixel. DLP (Digital Light Processing) An LCoS projector uses a small liquid-crystal display (LCD) to control how much light each pixel gets. The light source is white light based - either LED or diffused laser. LCoS (Liquid Crystal on Silicon) LBS projectors are different, creating the image one pixel at a time using a directed laser beam. If we scan the image fast enough(usually over 60hz) , we don’t notice this pixel-by-pixel design. Advantages to LBS over DLP and LCoS:- Focus free, Low power consumption and Small size LBS (Laser beam steering) Smart Projector Technologies (1/2)

- 7. Principles employed in Smart projectors (1/2) Bluetooth: Radio wave communication. It has a card-like attachment called Bluetooth adapter which sends and receives data. Flash Memory Cards: An electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. Wi-Fi: The radio signals are transmitted from antennas and routers that signals are picked up by Wi-Fi receivers, such has computers and cell phones that are ready with Wi-Fi cards.
- 8. Principles employed in Smart projectors (2/2) Combinational Optical System: Cannon implemented an LCOS (Liquid Crystal On Silicon) reflective liquid crystal panel in the image display device. It achieves high luminance, high image quality, and compactness. Images projected using LCOS do not have the black grid-like shadows which means the images are smooth and beautiful. High Precision Aspherical Lenses: It is developed using high-precision grinding technologies. It was needed because multiple multimedia projectors are often set up and used in combination, it is important that images are projected without distortion from corner to corner. Voice Assistance: These are virtual assistants which uses natural language processing (NLP) to match user text or voice input to executable commands. Hand-Gesture Controlled: Gesture control devices recognize and interpret human body movements, allowing the user to interact with a computer system.

Applications (1/2) • Cicret Smart Bracelet • A bracelet wearable that can project a touch-controlled screen onto our arm. • Cicret uses a Smart projector to throw your mobile’s screen into your arm. • It features eight proximity sensors which the bracelet uses to detect your finger position to feedback controls.
- 10. Applications (2/2) • Smart watches with Smart projector • It allows project an image with high quality graphics and brightness. • The watch doesn’t have any button, except of one touch sensitive button, with which you can manipulate the projection.
- 11. Challenges Faced • Budget can be stretched at businesses who invest in the latest software updates, but additional ongoing costs for IT assets can be hard to justify. • Usually wires run over the ceiling and into the wall to enable device c, making it hard to amend the basic of problems. Standing on a table in the middle of a meeting to resolve these issues aren’t the answer. • It’s a frequent occurrence that both obscures the view of the presentation and blinds the speaker at the same time. • Image quality gets lost from afar. Distorted colours, lines & dots on the images and faint projection create problem. Image Quality Speaker Shadows Maintenanc e Cost Installation & Logistics
- 12. Solutions • It is a collaborative workspace for teachers and students, groups of students, or the whole class to create and work on projects with multimedia content. • It allows the teacher to create a set of questions in under five minutes that students can answer on Chromebooks, desktop computers, smartphones or tablets. • Teachers can use gamification in classrooms to see greater retention of lesson as it’s fun way to deliver content to students who are already receptive to the action-reward system from playing video games. • it is used for hands-on learning and allows teachers to create engaging content. Teachers can install program on their home computer and send lessons directly to classroom. Smart Notebook Smart Lab Smart amp Smart Response

Which all companies have adopted it and what further research is going on into it. (Raspberry Pi, IOT) • What could be the life of our base technology (LCD) and which other technology has the potential to outplace it? (OLED-organic light emitting diodes) • What are various companies manufacturing smart projectors and what are the differences in their key/base/emerging technology? How every other brand is different from each other. • How companies are trying to create more value for the consumer and reduce the cost? Can you quote any architectural or modular innovation in projectors space to support your answer. • What solutions you would like to propose to solve your challenges presented here in your challenges slide.
