  • the bicycle 12 is fitted with a cycle computer wheel pickup 22 which senses the passage of a wheel magnet 24.
  • the wheel pickup 22 is typically a reed switch which is connected to the cycle computer via leads 26. Leads 26 terminate at contacts (not shown) in a handlebar mount 28 fastened to the handlebar 30 of the bicycle 14.
  • the cycle computer (not shown) is simply removed from the handlebar mount 28 and replaced with an interface unit 32 which clips into the handlebar mount 28.
  • the interface unit 32 has contacts which mate with the contacts connected to the leads 26 from the wheel pickup 22 mounted on one of the rear fork arms of the bicycle 14.
  • the interface unit includes a heart rate receiver circuit therein that receives a radio frequency signal from a heart rate sensor/transmitter band 34.
  • the user 12 fastens the band 34 around his/her chest.
  • a heart rate or pulse signal is sent normally from the band 34 to the user's receiver which may be a cycle computer such as a Vetta VHR-25 cyclocomputer.
  • the cyclocomputer is usually mounted on the bicycle handlebar.
  • the transmitter band is close enough (within about three feet) to the receiver in the cyclocomputer to receive the weak signals transmitted.
  • the heart rate receiver circuit in the interface unit 32 is located in the same place and is functionally the same as in the conventional cyclocomputer except that it generates a signal which is in turn fed to the CPU in the player 20 rather than a signal that is displayed on the handlebar mounted cyclocomputer.
  • the game CD player 20 is also connected to a remote game joystick controller or keypad 36 which is removably fastened to the interface unit 32.
  • the interface unit 32 is electrically connected to the standard accessory input port on the keypad 36 by a cable 38.
  • the keypad is connected to the game CD player 20 by game cable 40.
  • the game CD player 20 normally accepts several player keypads for additional users to play interactive games together by connecting one keypad to another keypad.
  • the interface unit 32 utilizes this feature to connect the interface unit 32 into the player central processing unit or CPU.
  • the exercise device in this example, a stationary bicycle exercise stand 16, includes a resistance means such as a variable friction resistance roller or wheel 42.
  • This friction roller may be set by the user manually, or optionally may include a servomotor connected to the interface unit 32 via leads 46. In this latter instance, the user may control the resistance setting via the keypad 36 and/or the resistance may be controlled automatically through the player 20 by the program in accordance with another aspect of the invention as will be subsequently described.

Therefore as the exercise rate increases, the frame rate of display increases, and the user sees the scenery flashing by faster. As the exercise rate decreases, the user sees the scenery pass by slower and slower, until the user stops and the scene displayed stops also. Thus the user gets the sensation of actually traveling through the scenery shown in the video.

However, if the Stop Video Flag is set, as when the user stops pedaling to rest for a period of time, control passes to a wait operation 106. Wait operation 106 is typically a process delay of on the order of 10 milliseconds, after which the query in operation 104 is performed again. If the Stop Video Stream flag is not set, control passes to operation 108.

Control then passes to operation 118.

In this case, operation 232 transfers control back to operation 228 and the current audio data chunk is replayed.

  • Operation 402 initializes several flags and registers to zero. Specifically, a load pulse flag, a heart beat flag, a heart tic flag, a wheel rotation flag and a wheel tic flag are set to zero. Also, a heart count register, a heart store register, a wheel count register, and a wheel store register are set to zero. The heart count registers and wheel count registers are used to accumulate time tics between input pulses from the heart rate receiver and the wheel rotation reed switch as will become more apparent below.

If a beat has been received, control passes to operation 418 where the heart count register contents are transferred to the heart store register. Then, in operation 420, the heart count register is reset to zero and the heart beat flag is reset in order to sense another heartbeat. Control then proceeds from operation 420 to operation 422. If no heartbeat has been received in the heart rate receiver, and thus the heart beat flag is not set, operation 416 transfers directly to operation 422.
  • operation 422 the query is made whether the wheel rotate flag has been set by passage of the wheel magnet 24 past the reed switch 22. If not, control passes to operation 424. If the wheel rotate flag is set, control passes to operation 426 where the contents of the wheel count register are moved to the wheel store register. Control then transfers to operation 428, where the wheel count register is set to zero and the wheel rotate flag is reset in order to sense receipt of another wheel rotation.
  • Operation 424 queries whether the heart tic flag is set. If so, control transfers to operation 432 where the heart count register is incremented and the heart tic flag is reset. Control then transfers to operation 430. If the heart tic flag is not set, operation 424 transfers control directly to operation 430.
  • Operation 430 queries whether the wheel tic flag is set. If so, control transfers to operation 434 where the wheel count register is incremented and the wheel tic flag is reset. Control then passes back to operation 406. If the wheel tic flag is not set, operation 430 passes directly back to operation 406.
  • the sequence of operations described in Fig. 7 is continuous. The net effect of the sequence is to constantly update the heart count, wheel count, heart store, and wheel store registers as wheel rotations and heart beats are received. This information is passed into the output registers for transmission to the 3 DO control system whenever the 3DO control program requests input which is about 60 times per second. It is to be understood that the above description is exemplary of one embodiment only.

Abstract

L'invention concerne un système, un appareil et une méthode de commande interactive de lecture vidéo en temps réel et de lecture de pistes audio. Dans un mode de réalisation préféré, l'appareil représente un système de vidéo interactif destiné à l'entraînement dans lequel on utilise un vélo, un détecteur de la vitesse d'une roue de vélo, une unité d'interface connectée au détecteur de la vitesse d'une roue de vélo et un contrôleur de jeu traditionnel, connecté à un lecteur traditionnel de jeux vidéo sur CD qui est connecté, à son tour, à un poste de télévision. Le lecteur lit un CD vidéo préenregistré, la vitesse d'affichage des images vidéo étant modifiée par un logiciel intégré au CD de sorte que la vitesse de la vidéo varie en fonction du niveau d'activité sur le dispositif d'entraînement. On modifie les variations de la fréquence d'images complètes en changeant l'horodateur de durée de chaque image vidéo complète utilisée par le programme de commande du lecteur, de manière à modifier le moment séquentiel auquel le lecteur vidéo appelle pour affichage chaque image complète. Les variations du taux d'affichage vidéo ne dépendent pas du taux de lecture audio. Pour maintenir la synchronisation de l'audio et du vidéo sans modifier le taux de lecture audio, des parties de l'enregistrement audio sont mises en boucle, c'est-à-dire relues.
