537 7 Titel Projicerat virtuellt inmatningssystem fOr fordon Uppfinningens omrAde Foreliggande uppfinning avser ett inmatningssystem, och en metod i samband med ett sadant inmatningssystem, enligt ingressema fOr de oberoende patentkraven. FIELD OF THE INVENTION The present invention relates to an input system, and a method in connection with such an input system, according to the preambles of the independent claims.

Speciellt avser uppfinningen ett inmatningssystem och en metod for ett fordon som underldttar kontrollen av system och funktioner pa fordonet. In particular, the invention relates to an input system and a method for a vehicle which facilitates the control of systems and functions on the vehicle.

Bakgrund till uppfinningen I en modern lastbil finns det flera system eller funktioner som fOraren, eller en passagerare, viii kunna anvdnda fran fOrarplatsen, fran passagerarplatsen eller fran andra stallen i, och i anslutning till, fordonet, exempelvis fran sangen eller utanfOr fordonet. Exempel pA sadana system eller funktioner är belysning, uppvarmningssystem, radio, tv, multimedia, men dven t.ex. installning av luftfjadringen fOr lastbilen, exempelvis i samband med att ett sldp kopplas pa. Background of the Invention In a modern truck, there are several systems or functions that the driver, or a passenger, can use from the driver's seat, from the passenger seat or from other stables in, and adjacent to, the vehicle, for example from the song or outside the vehicle. Examples of such systems or functions are lighting, heating systems, radio, television, multimedia, but also e.g. installation of the air suspension for the truck, for example in connection with a sldp being switched on.

Detta onskemal har idag uppfyllts genom att anordna knappar och reglage pa ett antal stallen i, och i anslutning till, fordonet som medger att systemen och funktionerna kan anvandas dven om anvandaren inte sitter pa fOrarplatsen. Exempelvis kan innerbelysningen styras fran en panel i anslutning till sangen. Ett annat exempel ãr att en fjarrkontroll fOr att stalla in luftfjadringen finns tillgänglig vid passagerarplatsen sa att den kan tas ut dA en kontroll sker. En sadan fjdrrkontroll är ofta ansluten via en kabel. This wish form has today been fulfilled by arranging buttons and controls in a number of stalls in, and in connection with, the vehicle which allows the systems and functions to be used even if the user is not in the driver 's seat. For example, the interior lighting can be controlled from a panel adjacent to the song. Another example is that a remote control for adjusting the air suspension is available at the passenger seat so that it can be removed when a control takes place. Such a remote control is often connected via a cable.

Det finns en rad exempel pa inmatningsgrdnssnitt fOr anvdndning i fordon och i det fiiljande kommer ett antal olika system att kortfattat diskuteras. There are a number of examples of input interfaces for use in vehicles and in the following a number of different systems will be briefly discussed.

US-7,248,151 avser ett virtuellt tangentbord fOr ett fordon som anvdnds i samband med att styra olika funktioner fOr fordonet, exempelvis fOr att lasa upp fordonet. Ett tangentbord projicieras exempelvis pa en sidoruta av fordonet. En detektor och en processor finns anordnade far att detektera gester och identifiera de gester som utfOrs pa tangentbordet. US-7,248,151 relates to a virtual keyboard for a vehicle which is used in connection with controlling various functions for the vehicle, for example for unlocking the vehicle. For example, a keyboard is projected on a side window of the vehicle. A detector and a processor are provided to detect gestures and identify the gestures performed on the keyboard.

Detektom kan exempelvis utgoras av en kamera eller en infraroddetektor. 1 537 7 US-7,050,606 avser ett system fcir att detektera och identifiera handgester som i syrmerhet är lampade fir att styra olika funktioner for ett fordon. Dessa funktioner avser exempelvis uppvarmning, luftkonditionering, belysning, CD/radioinstallningar, etc. The detector can, for example, be a camera or an infrared detector. US-7,050,606 relates to a system for detecting and identifying hand gestures which in particular are lit to control various functions of a vehicle. These functions relate to, for example, heating, air conditioning, lighting, CD / radio installations, etc.

I US-2011/0286676 beskrivs system och relaterade metoder avsedda for fordon fir att detektera och identifiera gester i tre dimensioner. Enligt en av metoderna ingar stegen att mottaga en eller flera obehandlade ramar med bilddata fran en sensor, att bearbeta och sla samman flera ramar for att identifiera kroppsdelar for anvandaren i fordonet, att berakna positionen for anden av handen fir anvandaren, att bestamma om handen har genomfort en dynamisk eller en statisk gest, att mottaga ett kommando som motsvarar en av ett antal lagrade gester, och att genomfora kommandot. US-2011/0286676 describes systems and related methods intended for vehicles for detecting and identifying gestures in three dimensions. According to one of the methods, the steps include receiving one or more raw frames with image data from a sensor, processing and merging several frames to identify body parts for the user in the vehicle, calculating the position of the spirit of the hand for the user, determining whether the hand has performed a dynamic or static gesture, to receive a command corresponding to one of a number of stored gestures, and to execute the command.

Har hanvisas aven till artikeln "Natural and Intuitive Hand Gestures: A Substitute for Traditional Vehicle Control", av A. Riener och M. Rossbory, publiserad i AutomotiveUI '11, November 29-December 2, 2011, Salzburg, Osterrike, Adjunct Proceedings. I artikeln beskrivs ett fors& ddr en forare via gester ger instruktioner for att styra ett antal funktioner. Vid forsoket har mycket av teknologin som anvands vid dataspel utnyttjats och da i synnerhet Microsoft Kinect som anvands for spelkonsolen Xbox. I forsoket har gester av handen utforda dá handen halls i narheten av vaxelspaken identifierats. En detektor i form av en kamera var monterad i taket och installd fir att infanga handrorelser i omradet runt vaxelspaken. He has also been referred to the article "Natural and Intuitive Hand Gestures: A Substitute for Traditional Vehicle Control", by A. Riener and M. Rossbory, published in AutomotiveUI '11, November 29-December 2, 2011, Salzburg, Austria, Adjunct Proceedings. The article describes a fors & ddr a driver via gestures gives instructions to control a number of functions. In the experiment, much of the technology used in computer games has been used, especially Microsoft Kinect, which is used for the Xbox game console. In the experiment, gestures of the hand were challenged when the hand held near the gear lever was identified. A detector in the form of a camera was mounted on the ceiling and installed to capture hand movements in the area around the gear lever.

Microsoft Kinect är saledes ett system som i forsta hand är anpassat for spelindustrin och som innebar att sensorer är anordnade i anslutning till en display ddr sensorerna omfattar en kamera och en 3D-sensor som kan, med stod av speciell mjukvara, detektera rorelser hos en anvandare i tre dimensioner och bland annat identifiera ansikten. Kinect-systemet anvands alltsa bland annat i spelkonsolen Xbox. Sensorn fOr tre dimensioner bestar av en infrarodlaserprojektor kombinerad med en monokrom CMOS-sensor, som kan detektera videodata i tre dimensioner i dagsljusferhallanden. Avkanningsavstandet kan stallas in for 3D-sensorn, och mjukvaran kan automatiskt kalibrera sensorn i beroende av vilket spel som spelas och spelarens fysiska omgivning, ddr hansyn kan tas till mobler och andra hinder. Systemet mojliggor avancerad rorelseigenkanning och kan samtidigt fOlja 2 537 7 rorelserna hos tva aktiva spelare dar rorelseanalysen kan ske genom att bedoma rorelsemoment fran upp till tjugo leder per spelare. Microsoft Kinect is thus a system that is primarily adapted for the gaming industry and which means that sensors are arranged in connection with a display where the sensors comprise a camera and a 3D sensor that can, with the help of special software, detect the movements of a user in three dimensions and, among other things, identify faces. The Kinect system is thus used in the Xbox game console, among other things. The three-dimensional sensor consists of an infrared laser projector combined with a monochrome CMOS sensor, which can detect video data in three dimensions in daylight conditions. The scanning distance can be set for the 3D sensor, and the software can automatically calibrate the sensor depending on the game being played and the player's physical environment, where he can take into account furniture and other obstacles. The system enables advanced motion recognition and can simultaneously follow the movements of two active players where the motion analysis can take place by assessing motion moments from up to twenty joints per player.

Kinect-systemets sensor matar ut videosignalen med en ramhastighet av 30 Hz. VideostrOmmen med RGB-signalen anvander en 8-bitars VGA-upplosning (640 x 480 pixlar) med ett fargfilter, medan den monokroma videostrommen for 3D-effekter har en VGA-upplosning (640 x 480 pixlar) pa 11 bitar, som ger en kanslighet i 2048 niva.er. Kinect-sensom fungerar pa avstand Mom omradet 1,2-3,5 meter da den anvands i samband med mjukvaran till Xbox, men kan ra ett utokat omrade som ligger inom 0,7-6,0 meter. Sensom har en horisontell detektionsvinkel ph 570 och en vertikal som är 43°. Sensom kan sedan vridas 27° i horisontell led. The Kinect system sensor outputs the video signal at a frame rate of 30 Hz. The video stream with the RGB signal uses an 8-bit VGA resolution (640 x 480 pixels) with a color filter, while the monochrome video stream for 3D effects has a VGA resolution (640 x 480 pixels) of 11 bits, which gives a possibility i 2048 niva.er. The Kinect sensor works at a distance of Mom in the range of 1.2-3.5 meters as it is used in connection with the software for the Xbox, but can be an extended range that is within 0.7-6.0 meters. The sensor has a horizontal detection angle ph 570 and a vertical that is 43 °. The sensor can then be rotated 27 ° horizontally.

For att ge foraren av ett fordon mojlighet att utnyttja de manga olika system och funktioner som idag finns i en modern lastbil finns ett flertal knappar och reglage anordnade i fordonet, inte bara i anslutning till fOrarplatsen utan exempelvis vid sangen och i form av fjarrkontroller. Dessa knappar och reglage haver ofta separata kabeldragningar vilket gör monteringen komplicerad och innebar hoga kostnader. Dessutom kan det ibland vara svart for fordonsforaren att veta var knappama sitter for en specifik funktion. To give the driver of a vehicle the opportunity to use the many different systems and functions that are present in a modern truck, there are several buttons and controls arranged in the vehicle, not only in connection with the driver's seat but for example at the song and in the form of remote controls. These buttons and controls often have separate wiring, which makes installation complicated and entails high costs. In addition, it can sometimes be difficult for the driver to know where the buttons are for a specific function.

Syftet med foreliggande uppfinning ãr att astadkomma ett forbattrat inmatningsgranssnitt som bade är mera anvandarvanligt och som innebar en kostnadsbesparing fOr fordonstillverkaren. The object of the present invention is to provide an improved input interface which is both more user-friendly and which entailed a cost saving for the vehicle manufacturer.

Sammanfattning av uppfinningen Ovan namnda syften astadkommes med uppfinningen definierad av de oberoende patentkraven. SUMMARY OF THE INVENTION The above objects are achieved by the invention defined by the independent claims.

Preferred embodiments are defined by the dependent claims. The input system of the present invention combines a projector system and a detector system adapted to detect a person's body motion.

Vid implementeringen av inmatningssystemet enligt uppfinningen anvands miniatyrprojektorer och kamerasystem som bland annat awn anvdnds i samband med datorspel, exempelvis Microsoft Kinect som anvands i spelkonsolen Xbox (som beskrivits ovan). In the implementation of the input system according to the invention, miniature projectors and camera systems are used which, among other things, are used in connection with computer games, for example Microsoft Kinect which is used in the Xbox game console (as described above).

Enligt uppfinningen projiceras en virtuell pekskdrm pa en onskad yta i eller utanfor 10 lastbilen och anvands vid inmatning av styrinstruktioner till system och fimktioner i fordonet. Systemet anordnas exempelvis i innertaket av lastbilen sa att den virtuella skarmen kan projiceras pa varje tankbar position. According to the invention, a virtual touch screen is projected on a desired surface inside or outside the truck and is used in inputting control instructions to systems and functions in the vehicle. The system is arranged, for example, in the roof of the truck so that the virtual screen can be projected at any conceivable position.

Pekskdrmen kan exempelvis projiceras pa vaggen vid sidan av sdngen, pa madrassen, pa sdngen, pa golvet eller pa vaggar. Star man utanfor fordonet kan man projicera den virtuella pekskdrmen pa en platta man hailer i handen eller exempelvis pa dorrens insida eller pa insteget. The touch screen can, for example, be projected on the cradle next to the bed, on the mattress, on the bed, on the floor or on the cradles. If you stand outside the vehicle, you can project the virtual touch screen on a plate you hold in your hand or, for example, on the inside of the door or on the entrance.

Ddrigenom kan man ersatta flera knappar i lastbilen, till exempel fjarrkontrollen for luftfjddringen, belysningsknappar och kontrollenheten for uppvarmningssystemet. Vidare 20 finns mojligheten att sjdlv kunna definiera vilka system och funktioner som skall kunna kontrolleras via den virtuella pekskarmen. This allows you to replace several buttons in the truck, such as the remote control for the air suspension, lighting buttons and the control unit for the heating system. Furthermore, there is the possibility of being able to define which systems and functions can be controlled via the virtual touch screen.

Vid tillampning av foreliggande uppfinning erhalls ett system som dels är mera anvandarvanligt genom att tillgangligheten for styrning av fordonets olika system akar. 25 DeIs innebar det en kostnadsbesparing for tillverkaren av fordon eftersom exempelvis mindre kabeldragning kravs och farre knappar och styrenheter behovs. In the application of the present invention, a system is obtained which is partly more user-friendly in that the accessibility for controlling the various systems of the vehicle increases. 25 DeIs meant a cost saving for the manufacturer of vehicles because, for example, less cabling is required and fewer buttons and control units are needed.
